It's galaxy time! Which means it's going to be cloudy. Figures. Since the vast expanse of galaxies and clusters of galaxies become visible in the shoulder seasons of Spring and Autumn, the weather in these parts can turn mighty cloudy and cloudy for some time...If you suffer from SAD, you have my sympathies...the only thing I don't like about my scope or the Mallincam is that they still can't see through clouds. <br />

But I have had some modest success this Autumn as I began my journey into video astronomy with the Mallincam DS2.3+, although before that I was having some success with the AGc as well earlier on. In my previous two posts I alluded to the far reaching implications of the Mallincam to explore into some truly remote objects, something I refer to as the abyss, which is really my arbitrary "beyond the 12th magnitude wall".<br />
<br />
Lets have a look at some early results. Remember, when it comes to processing these images, I am a total noob. My primary objective at this time is to search, find and explore. Processing will come later as I sharpen my skills.<br />

Acquired under Bortle Scale 7 skies, a waxing gibbous moon, questionable transparency and a novice understanding of such and object...and well...there it is anyway! The Abell Challenge is on and this just the beginning. This is the abyss I have been talking about. The ability to explore, and I mean really explore the universe. Acquired with the 102mm achro and the DS2.3+, gain at 20 and 45 sec. exposure. <br />
<br />
<b>The best is yet to come</b><br />
<br />
I'll be honest, I haven't felt this excited about astronomy since I was a teen. Really. So I cannot thank Van and Rock enough for providing an experience that has matched what it was like when it all began. There have been highs and lows in this hobby, and this is one incredible ride. Lets see where it goes. <br />

<div style="margin: 0px 0px 11px;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">The following is a speculative piece that is the result of
the so-called personal revolution that the Mallincam AG-c and DS2.3+ has
triggered in the last couple of months.<span style="margin: 0px;">
</span>I could be wrong or right, or I will touch a nerve.<span style="margin: 0px;"> </span>Either way, I hope it generates discussion. The
prime argument for the revolution was the ability to actually do observing in
heavily light polluted skies.<span style="margin: 0px;"> </span>A <a href="https://apnews.com/5de588e62104434fb66e73973ff0c22e/Good-night,-night:-Light-pollution-increasing-around-globe">recent article</a> suggests that, despite our technology, best intentions and
awareness, light pollution has actually gotten worse.<span style="margin: 0px;"> </span>This is bad news.<span style="margin: 0px;"> </span>Bad news indeed.<span style="margin: 0px;"> </span>But this isn’t primarily what I’m on about
here.</span></div>
<br />
<div style="margin: 0px 0px 11px;">
<b><span style="font-family: "arial" , "helvetica" , sans-serif;">The Issue</span></b></div>
<br />
<div style="margin: 0px 0px 11px;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">Pick up any beginners guide to or a book about
astronomy.<span style="margin: 0px;"> </span>You’ll notice a particular
pattern.<span style="margin: 0px;"> </span>The reader is enticed by
beautiful pictures of the night sky and lavish ads (if a periodical) and images
of equipment.<span style="margin: 0px;"> </span>The text goes on extolling
the virtues of backyard astronomy in lavish terms like “this is the greatest
hobby out there”.<span style="margin: 0px;"> </span>THIS is who you want
to be in astronomy.<span style="margin: 0px;"> </span>Then as predicted,
comes the big let-down, the anti-climax, the scary phrase “you won’t see things
like in the photographs”.<span style="margin: 0px;"> </span>Then comes the
deflection of “this is a cerebral journey” and “you have to imagine these
objects like in the pictures”.<span style="margin: 0px;"> </span>The
journey is indeed cerebral, but putting it like this makes it look like a bait
and switch.<span style="margin: 0px;"> </span>Why did we entice them with
pictures in the first place and then dodge the issue with such statements?<span style="margin: 0px;"> </span>I’m not sure this is an honest thing to do.<span style="margin: 0px;"> </span>There is a possible solution to this big let
down…</span></div>
<br />
<div style="margin: 0px 0px 11px;">
<b><span style="font-family: "arial" , "helvetica" , sans-serif;">Let them actually see stuff!</span></b></div>
<br />
<div style="margin: 0px 0px 11px;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">The whole idea is to see something.<span style="margin: 0px;"> </span>If you are content with seeing faint smudges,
and limited to observing very rarely because the drive is too much or you don’t
have time, then so be it.<span style="margin: 0px;"> </span>But this is where
the Mallincam came through for me.<span style="margin: 0px;"> </span>The
ability to see things, in light polluted skies and in colour and with
detail.<span style="margin: 0px;"> </span>The very thing that most
beginner’s guides say CANNOT happen.<span style="margin: 0px;">
</span>Sure, it’s not the same as intense DSLR or CCD imaging, but it’s getting
closer to it and I feel it’s a whole lot easier to do.<span style="margin: 0px;"> </span>And there are those who argue that staring at
a monitor is not aesthetically pleasing.<span style="margin: 0px;">
</span>There could be some truth in that especially for the planets or those
Milky Way vistas in binoculars.<span style="margin: 0px;"> </span>But for
the deep sky, and I mean “deep”, I have moved on.</span></div>
<br />
<div style="margin: 0px 0px 11px;">
<b><span style="font-family: "arial" , "helvetica" , sans-serif;">A Mallincam with every beginner scope?</span></b></div>
<br />
<div style="margin: 0px 0px 11px;">
<span style="font-family: "arial" , "helvetica" , sans-serif;">That’s a bold statement.<span style="margin: 0px;">
</span>Certainly the computer savvy beginner shouldn’t have much of a problem
using the most basic Mallincam.<span style="margin: 0px;"> </span>Some
might argue that the cost is prohibitive for the more advanced Mallincam
cameras, but think about how much a couple of decent wide field eyepieces are.<span style="margin: 0px;"> </span>Currently gas prices are almost a 1.23 per
litre so some might hesitate to travel 60-90 minutes to a dark sky.<span style="margin: 0px;"> </span>Even worse, what could happen is user
frustration and a golden opportunity to explore is lost because the view simply
wasn’t there.<span style="margin: 0px;"> </span>The scope then ends up on
Kijiji and it’s over.<span style="margin: 0px;"> </span>So yes, I could
advocate that a Mallincam is most certainly worth with a beginner
telescope.<span style="margin: 0px;"> </span>Why not?<span style="margin: 0px;"> </span>If it tracks (computerized or not), go for
it!<br />

<br />
<br />
I haven’t blogged for some time about astronomy, more like almost four years now, mainly because the blog interface is nowhere near as good as interacting on Facebook which is where I primarily interact about astronomy in general. But what I am talking about is a major shift in how I “do astronomy” and that is something that needs to be expanded upon. What this isn’t is a technical discussion about the Mallincam video astronomy camera (I am simply not qualified to do that). This is a personal reflection on how video astronomy has changed how I approach conventional visual astronomy.
<br />
<br />
<b>When it started</b><br />
<br />
At an astronomy convention a light bulb went on. The Celestron Evolution was just released to the public and it got me thinking about how we observe and do astronomy. You see, that scope interacts with your smart phone or tablet. If you think about it that sounds a tad silly given one requires night vision to observe. But what if you were doing something different such as video astronomy or imaging where night vision is largely a moot point. I already knew I had neither the time nor patience for astrophotography, so I decided to run this idea by the guys at Mallincam, thinking maybe, just maybe this is the type of scope that would be a great fit for video astronomy. It is at this time I began a friendship with someone named Van…who ultimately would alter my entire trajectory in this hobby.
<br />
<br />
<b>The First Revolution…Mallincam AG-c</b>
<br />
<br />
Van was kind enough to loan me the starter Mallincam, the AG-c. Basically a guider that can act as a stand-alone video camera for astronomy. I wasn’t exactly sure what I was given but to put it to the test, I chose the TV76 and the EQ6 mount (just a tad over mounted) to start. I figured the 480mm focal length was more forgiving than the 102mm’s 1000mm focal length and to be honest, wasn’t sure the 102 would actually work (it did, but it wasn’t the best choice for this camera). So that’s how I got started. It was also the beginning of the end of one thing, and the beginning of something else.
<br />
<br />
<b>You’re supposed to see stuff, right?</b>
<br />
<br />
Conventional wisdom states that in order to actually “do visual astronomy” one must face a drive of one hour or more to actually see something. Living in the GTA due to urban sprawl, that drive is probably more like ninety minutes, assuming rush hour isn’t in full swing. If I don’t make that drive I am stuck in my driveway, with an obstructed view and limited skies due to light pollution. My work schedule makes it even harder to travel to a dark sky. So I am limited to Friday or Saturday evenings and everyone knows those evenings are almost always clear, right? Yeah okay. So the idea of astronomy is to see stuff…but I wasn’t…well not deep sky objects…which is/was depressing…because we ARE supposed to see stuff…

<b>What the Mallincam/TV 76 did</b>
<br />
<br />
I saw stuff! Okay so I saw it on a laptop. But who cares! I SAW STUFF! But put that in perspective. Not only did I see stuff, I saw stuff that by conventional means (through the eyepiece) is basically impossible especially in the city with limited aperture. But suddenly, faint NGC’s became possible…in my driveway…in the city…and that is where things change dramatically. I felt like I was observing, really observing objects without the treacherous (or is that torturous) drive to a dark sky. Now to be fair, it would be much better under a dark sky. So I went to StarFest with this combination and I looked at stuff that no 76mm aperture ever dares to go after. You know, like Stephan’s Quintet and the Perseus galaxy cluster. And yet, I was able to see these things.
<br />
<br />
<b>The Second Revolution…Mallincam DS2.3+</b>
<br />
<br />
Van, being the kind human being he is, loaned me something I’ll never forget. The Mallincam DS2.3+ only this time with reducers which could lead to possibly using the Mallincam with the old refractor. Now, the old refractor, even though it was modernized and rebuilt, was taking a backseat to the TV76. I first tested the DS2.3+ with the TV76 and the results were very promising and I was able to penetrate further into the abyss. But I was curious about linking this to the 102. Remember, this is an old dreadnought of a scope. Built in the era of big hair and shoulder pads. It was never intended for this use. After a false start not getting it to focus, I decided to go straight through the scope so the reducers could be used and of course that actually worked after some daytime fiddling with the focus.<br />
<br />
<b>Get on with it! What did you see?</b>
<br />
<br />
Stephan’s Quintet…set up on my driveway…in skies I cannot see the little dipper in…need I say more? Well yes, I did see A LOT of other stuff too.
<br />
<br />
<b>Remember that atlas you own?</b>
<br />
<br />
I always felt that I faced a wall around 12th mag. You know, that point where everything ends but you know damn well it’s just the beginning. Even a large dob wouldn’t go past the wall in urban skies. If it did it would be too huge to work with. So I would stare at my Uranometria looking at all those inaccessible fuzzies of 13-15th mag. Except maybe they aren’t. Given what I have already tried, it seems almost ridiculous to say that I have been out to 14th mag from my driveway, but with the combination of the 102 and the DS2.3+, this is what has happened. Incidentally, I became recently aware that the TV76 and AG-c combo went over the 12th mag wall too. That was an eye opener. So yes, remember that atlas? Now I am putting it to use. Which leads me to the next thought. <br />
<br />
<b>Access to the abyss</b>
<br />
<br />
That is what I am talking about. The ability to explore without the inherent problems of commuting to a site or not having sufficient time due to scheduling and hauling out huge pieces of equipment that require a set up time. It is true my combination of the DS2.3+ and my two refractors would work A WHOLE LOT BETTER in dark skies but the point is, the abyss is accessible from my driveway in far less perfect conditions. And that is what excites me the most. Exploring is what I do. That is what drives me to observe. The Mallincam has opened the abyss.
<br />
<br />
<b>Did I kill visual astronomy?</b>
<br />
<br />
No. Better yet, I supplemented it. There will be those of the traditional thought that the eyepiece is more aesthetically appealing. I too love looking through the eyepiece and I still love to observe double stars through them not to mention the planets. But for faint stuff, I’ve gone another route and I am not sure I will return…

I’d like to thank Rock Mallin for making great stuff. He has opened the universe up in a way I never really thought possible and to be able to use such legacy equipment like the 102 achromat, makes it even more special. And of course a big thank you to Van, because without his kindness, this would never have happened…and I’d be stuck in a rut looking at the Moon…but there’s nothing wrong with the Moon…it just doesn’t end there…

I have only spent a limited amount of time with the old (newish looking) SP-C102 which was returned to me from <a href="http://www.astroshrink.com/">Astroshrink</a> who did a wonderful job restoring the scope to bring it back to the forefront of the observing experience. Last night I managed to set it up to catch Jupiter rising in the east. It is important to note that the internals of the Refractor have been slightly altered to include flocking (in sections) and spray painted to a deep black. This has resulted in a higher contrast instrument with a better stray light management than in the past. The remounted cell was still in collimation after performing a "Rigel Test" (right, I was really going after the companion! Saw it! :) and the scopes collimation was spot on despite being removed and cleaned during the tube restoration process. M42 was breathtaking, as breathtaking as it can be in a 102mm refractor. However the contrast has been improved as a result of the aforementioned flocking and painting.
I hope to do a more in-depth report but the forecast has turned sour for the week...I guess it's my fault.
Enjoy some pics from the past, during the restoration (courtesy of Astroshrink) and after the restoration

If you restrict yourself to just observing deep sky objects, the Moon will get you down.
But if you like double stars...different story.

The Full Moon blazing away did not present too big a problem (shot with my phone)
<p>
Working with the Antares 105 f/15 and my favourite Struve List (which is so huge I will never finish it) I had some modest success down to about 10th magnitude in the usual washed out view that is the Full Moon. I figure it is best to get some observing in as weather was about to turn on us and limiting one self to the moon phases is self-defeating. Seeing was so-so and I was limited to just about 2.0 arc seconds. No pushing the theoretical limit that night! Some of the best views were Struves of equal brightness down around 9th magnitude with a relatively easy split. Lots of fun!
<p>
Which kind of leads me to the main point of this entry. Assuming your observing criteria is not always "Moon sensitive", it is my opinion that you should take full advantage of clear skies when you get the chance because we all know just how rare they are in humid Southern Ontario. Besides, double stars are fun and it becomes addictive to push the limits of your vision and equipment. Double stars tend to have quite the "cult following". Deep sky objects will be washed out but I still enjoyed pleasing views of the Pleiades cluster which was blown out because of the long focal ratio...but anyway it was still a lot of fun just to get out and explore...

This logic doesn't just apply to the TV76, it applies to any and all small, quality refractors.
Built like a tank. How many times have you heard that phrase about this class of telescope? It harkens from the Tele Vue Pronto days that has been the hallmark of the small Tele Vue refractor lineup. Heavy duty in a small package. Structurally these scopes are truly overbuilt with buttery smooth focusers, sliding dew shield, accessory clamshell and a powder coated white tube. I did not opt for a green tube.
<p>
<b>Optics, build and accessories</b>
<p>
My ’76 is actually a used one, not new and is slightly older than the current crop with a different eyepiece holder and it doesn’t have the satin body, it has the older machined shiny body. If anything, I would like to swap out the eyepiece holder as the newer version is an upgrade with dual screws, not one. But the one I have is still sufficient as it too is a compression ring style. It’s tank-like build is sometimes criticized as it’s Achilles heel because it is generally heavier than it’s birding counterparts, but when compared to larger telescopes, it really isn’t that much of a pain. Still birders will prefer rubber bodied, waterproof, gas charged spotting scope in exchange for the views because, you guessed it, the ’76 is not a waterproof scope and as a conventional refractor in terms of structure, focusers are classic rack and pinion with a 2” eyepiece capability that results in mirror reverse images. Birders may prefer the more traditional upright, left to right view. I however, am not one of them. I prefer to keep the image as pure as possible. To keep the tube relatively thin, the scope is not baffled, it is flocked.
<p>
Optically this scope is great. But so what. Let’s qualify that statement. Obviously it’s light years ahead of its older sibling, but never mind that. Pronto vs TV76 is a fruitless discussion because they are completely different refractors. Structurally similar, but that’s it. Nothing to talk about there and it has been done to death on <a href="http://www.cloudynights.com/category.php?category_id=13&pr=2x6">Cloudy Nights</a>. However, for buyers looking at used Pronto’s, don’t worry, it’s still a great achromat and worth the investment. Just be careful not to overpay on one because, put simply, you can get great optics from other ED Refractors that are much more modern even though you might sacrifice the build. My 76 exhibits what is typical in an SD doublet (it is assumed that it is in fact FPL-53 but I don’t think it has ever been directly stated) where you will find the in-focus image to exhibit next to little false colour on bright objects. Out of focus images do produce some false colour as expected. Concentric rings are nicely visible and the out of focus image does not indicate any correction issues, astigmatism, collimation problems or rough images. A nicely made lens. If anything, it has been on more than one occasions, been the “gold standard” to judge by in it’s class and only in it’s class not beyond it. The lens is held in collimation with no user adjustment. If it goes out of collimation, it has to go back to the factory. A Starbeam Reflex site as well as a Vixen/Synta finder scope base was added to enhance it’s capabilities with an 8X50 finder scope, although one can argue you might not truly need a finder. The clamshell has been adapted to the ADM 7” Vixen Universal Plate so it is compatible with all Vixen and Synta style saddle plates. It will ride on a variety of mounts like the AZ-4, EQ5 and EQ6.

<b>Working with the Tele Vue 76</b>
<p>
Vega Test: Well, I didn’t do one and I don’t really want to do one.
<p>
Venus Test: I haven’t done that either. I might one day…
<p>
Planets: I have truly enjoyed this scope on Jupiter and Saturn despite the smaller aperture. I have at least detected the Great Red Spot Hollow on more than one occasion, enjoyed tracking transits of the Jovian moons and it is no problem spotting the C Ring and Cassini’s Division. Don’t think I have ever spotted the Encke Gap, but I don’t think I went looking for it in the first place. I’ll have to check next year. I have not seriously looked at Mars though with the ’76 and a review of it pointing out that any f/6 ED doublet APO might not be the ideal “Mars Scope” can be found<a href="http://scopeviews.co.uk/TV76.htm"> here at Scopereviews in the UK</a>.
<p>
Deep Sky: With just an aperture of three inches, this is going to be relegated to the brighter deep sky objects but there have been plenty of nice views to be had here. None of them are surprising. What I won’t do is compare this to say, a large Dobsonian. This is nonsensical because they aren’t in the same class of instrument. Besides, to state that “a dob blew away the ’76 on faint object X” is more than enough of a statement of “Captain Obvious”. The grandest thing is the wide field. M31 has that galactic feel to it in a dark sky. With a five degree field at maximum, it has been the preferred view at StarFest over much larger instruments with a narrower field. Open clusters like the Beehive, Coat Hanger and Pleiades look like open clusters that you could only fathom in your 8X50 finder scope on larger instruments. The Double Cluster is bordering on glorious in a five degree field. Truly an experience to behold. There is something to be said while taking the whole view in of Orion’s Sword region where M42 reigns supreme. It’s something you have to experience. Reading about it doesn’t do justice. Any quality f/6 doublet ED/APO can do this.
<p>
This is not a “Herschel Hunter” nor should it be considered as such. It’s a different approach to the traditional deep sky observing. I would treat the ’76 as a nice supplement to your larger telescope.
<p>
Double Stars: This is not my primary telescope for double stars, that is reserved for my larger refractors but views have been rather pleasant in the ’76 especially colour contrasting doubles where the APO optics do help. The focal length of course is short at 480mm so “barlowing up” is required or get some of those high quality, low focal length eyepieces. The scope is capable of operating very well up to 200X. Some of the finer splits have been Porrima, Castor, Rasalgethi (Alpha Herculis) and Rigel (split surprisingly well).
<p>
<b>Crossing over to the other side</b>
<p>
Crossing over as a multi-function scope is where I think this scope really shines. I actually purchased it for the ability to photograph birds and wildlife on top of the astronomical capabilities already stated. It extended my options to 480mm (760mm crop factor) with the camera and I have been more than satisfied with the results and if you saw my post from <a href="http://thebackyardastronomer.blogspot.ca/2013/09/tele-vue-76-invades-rattray-marsh.html">Rattray Marsh</a>, you’ll see why. However, one must remember that dealing with a conventional refractor focus is much trickier than the instant auto-focus mode of my 70-200 L. When you do get the focus right, and it takes work, it’s a nice image as seen from my Rattray Marsh post. I have not used the ’76 as much as I would like visually in this capacity, but what I can say it is breathtakingly bright, crisp and virtually false colour free as expected and keeps up with the big kids on the birding scope scene like Swarovski, Leica, etc.
<p>
I have been working with the ’76 for some concepts as a terrestrial or landscape imaging telephoto. This is really out of the norm for an astronomical telescope as I have not seen many people attempt it. My 70-200 L is truly my go-to landscape lens but I decided to see what the ’76 could muster. It’s a strange, unique world indeed as these photos indicate. As mentioned in my Rattray post, the Orion Field Flattener is a BIG help here to keep images sharp across the focal plane. It may not be the most efficient scope for this purpose, but it’s fun to tinker and go outside normal boundaries. Canon does make 500mm and 600mm lenses…have you seen the prices? Have a look at some of these concepts.

We established the TV76 as a capable Air Show supplement to existing lenses <a href="http://thebackyardastronomer.blogspot.ca/2013/09/an-air-show-of-tele-vues-and-other-stuff.html">here</a>
<p>
Can you hike it? The simple answer is yes with conditions. The weather has to be fairly nice. The ’76 is a fair weather friend. Weighing in at five pounds, it's bulk in contrast to lighter, rubber-armoured spotting scopes could be an issue but short hikes are reasonable. One must keep in mind that the supporting cast is larger than most spotting scopes depending on what it’s intended for. One must take a robust tripod capable of supporting it well, eyepieces, barlows and a diagonal, camera adapters, field flattener( again I find it useful), and camera bodies. Given that list, it’s clear one must be dedicated to this kind of activity. If doing an overnight backpacking trip is in order, chances are, the ’76 is not your scope. Short hikes, possibly day hikes can be done with the above conditions IF you want to do it.
<p>
<b>Some other thoughts</b>
<p>
Despite all that has been written, what place does this little refractor have in the era of the (modestly) inexpensive ED/APO doublets from Asia? Well, given it’s price new, the TV76 is a big investment. But what you do get is a capable telescope/terrestrial scope that’s built to last forever, assuming you treat it right. Now, I do have many friends who have invested in small ED/APO doublets imported through SkyWatcher, Explore Scientific, Astro-Tech, etc, and I can say these scopes can deliver as good as or very close to the TV76, optically. They may have not subjected their refractors to the rigors that I have as stated above but I cannot say anything negative about them only positive things which might lead some to wonder why I even bothered to post this at all. My attempt here was to lay out what you can do with a small refractor in this class. There are many debates about the merits of this or that refractor and it’s been done to death. Some say Tele Vue’s quality will last forever. That may be true, but if you treat your telescope well, chances are it will last just as long. Treat it badly and well, you know what happens. There is no real need to debate this anymore except where quality control may be a factor. Tele Vue’s reputation as a fine optical maker cannot be disputed and every unit that leaves the factory is essentially guaranteed to deliver as promised. That reputation in and of itself might sway owners to it.
<p>
As a result of the influx of imported doublets, the used value of the ’76 is taking a beating. Units can be purchased for under a thousand USD which was unheard of a few years ago. So it’s a buyers’ market in the used department.
<p>
Bottom line is this. The concept of a small, quality ED/APO doublet is indispensable as indicated above as they can go anywhere at a moments notice. Portable and hike-able with some restrictions. If you choose a TV76, the quality, build and endless possibilities...you will be <i>more</i> than happy.
<p>

<p>
It's a conversation that crops up when friends desperately want to observe in dark skies on that rare weekend but don't want to face going alone. So they try and reach out but to no avail. Dark sky sites sit empty on pristine nights. Why?
<p>
My good friend Nicole explains the benefits of actually joining a club <a href="http://www.itelescope.net/doc-astro/2013/9/9/astronomy-clubs-invaluable-resources-for-everyone.html/">here</a> and explains it better than I can. So please do me a favour and read her blog entry.
<p>
The answer or answers most likely do not point to a single cause but many contributing factors. However, it is somewhat alarming to hear this chatter. Organized groups that are floundering because of lack of attendance, interest what have you is common place today. But I have to pause a moment and consider if the statement is true that organized astronomy is dead.
<p>
Visit a Saturday night at the <a href="http://theddo.ca/">David Dunlap Observatory</a> and tell me it's dead...Really...is it "dead", "mostly dead", or "I feel happy"?...
<P>
One of the best things and perhaps the most unique thing about this hobby among others is that you make it what <i>you</i> want. There is no "Gold Standard" to govern your choice. You don't pick "HO Scale" and build from there. You pick whatever tools you need to make <i>your</i> astronomical experience the best for you. So the idea of it being accessible is not in question. Anyone can "do astronomy". It is perhaps one of the most beginner friendly hobbies out there. Get a great book, and go out and look. That's it.
<p>
Except that...astronomy is becoming increasingly inaccessible...
<p>
Light pollution has all but wiped out the traditional 60 minute drive and pushed it into 90 minutes or more to get that great view. There are still pockets of dark near the GTA within 60 minutes but going out on your own finding a spot might prove troublesome. With fuel costs pushing 1.40 per litre in the GTA, a lot of people might not want to do it never mind the actual time invested, the late night drive back, and the lack of sleep the following morning. Light pollution is most likely the number one killer of organized observational astronomy.
<p>
As a result of being squeezed (or hosed) at the pump, a lot of us are relegating our observations within that awful light dome called the Greater Toronto Area where we still can get our lists semi- completed, observe double stars and a handful of deep sky objects that keep us interested. Others who make an investment into video astronomy, are able to view fainter objects via a screen and a nifty camera made by companies like Mallincam. We crave dark skies, but can't find the time, rationalize the fuel consumption or find friends willing to do it. And if we do travel, it's maybe once a month or perhaps a few times a year like StarFest, the Algonquin Adventure, Manitoulin.
<p>
There other points to consider of course:
<br>
-Shyness or prefers to go at it alone (lone wolf observing is not a bad thing, some prefer it)
<br>
-Previous bad experiences
<br>
-Snobbery or "Old Boys Club" (this in fact is in a death spiral of it's own, thank the stars!)
<br>
-Lack of interest or "does not apply"
<br>
-Limited opportunities for growth etc, etc.
<br>
<p>
The list could go on and on....
<p>
Don't get us started about the weather either. This is becoming an embarrassment in Southern Ontario as we gamble against forecasts that seem to tell nothing but lies. Where pristine skies are promised, hopes are dashed, dreams crushed as transparency falls apart around us and we pack up wondering why we even bothered to try in the first place. Yes, all that money spent on fuel, food and time preparing for it seems so wasteful. You can bet this is a major factor too, if not one of the most prominent.
<p>
It might seem to be all doom and gloom, but it really isn't. The DDO Saturday and members nights are flourishing which is a positive sign. Mississauga has adopted a new street light campaign and is phasing out the older and crummy high pressure sodium street lights with fancy, full cut off LED lighting. You can learn about that <a href="http://www.mississauga.ca/portal/residents/ledstreetlighting">here</a>. It will be interesting to see how much that will affect local conditions in my current city given our one site is by the lake which is not a bad site. We have spotted double stars down to magnitude 11.
<p>
Wherever you find yourself in this hobby, enjoy it, indulge in it and share it with the locals and friends. And if you feel the need to include yourself in "like minded groups", do yourself a favour, find a local club....
<p>
Last night we gambled...and sort of won and lost. It was fun knocking off a few Herschel Objects, but also nice to get a pic like this to take back. That dead piece of wood is pointing the way...will you follow too? Image from Tiny Marsh near Elmvale.

If you visit there and block out that usual drone of the city surrounding it, you'd think you would have entered a wilderness zone. Alas, that is not the case, but Rattray Marsh is nicely tucked away between a subdivision on one side and a municipal park, Jack Darling Memorial on the other. I had spent the morning photographing the sunrise at Jack Darling and then moved over to Rattray later in the morning as the sun came up. Once again, I used the Bexhill Road entrance which has easier access to the marsh's observing area although this time, I entered from the lake shore instead of setting up on the boardwalk. That involved a little walk on the beach (and yes I was still looking for fossils at times!). Rattray at times can be inundated with A LOT of people on weekends. If you can slip away during the weekday, DO IT. It's much quieter. You will feel like you have it all to yourself.
<p>
The set up.

I brought in the Tele Vue 76 for it's portability although it is still a chunk to carry around. It fits nicely in a spotting scope back pack with the camera body, a couple of Tele Vue eyepieces and other items that have to be carried out just because...I also employed an Orion Field Flattener to sharpen the edges. This is not typically required for this kind of photography but then again for whatever reason, it helps me focus. So I guess I contradicted myself...I suppose it's required...for me anyway.
<p>
I don't particularly like to make much noise when I do this because it disturbs the birds but my arrival did not seem to flush them out. The '76 went up quickly and I got all the camera gear up and running without a hitch...and basically stood there. Suffice to say, limiting my movements and keeping quiet went a long way. I was visited by a Great Blue Heron, a Green Heron, Northern Harrier (most likely looking for an easy meal no doubt), Killdeer, and a mocking Belted Kingfisher among others, that proved to be harder to photograph. I felt it was laughing at me. I also had our usual friends, the Canada Goose, Mallard Duck and of course a couple of dog walkers breaking the quiet.
<p>
I have yet to do a proper or thorough impression or thoughts on the Tele Vue 76 mainly because it's results will speak for itself. As an awesome grab-and-go astronomical telescope, I have pressed it in to service as a birding/terrestrial (<a href="http://thebackyardastronomer.blogspot.ca/2013/09/an-air-show-of-tele-vues-and-other-stuff.html">and air shows!</a>) telephoto lens, an effective alternative to the Canon L Lens series. But does it deliver? Let the results speak for themselves. It should be noticed that I am using an older Canon 30D to take these pics. Todays DSLR are vastly improved over what I have in terms of noise reduction so take it with a grain of salt. If anything, I have always found focusing the '76 to be the hardest part of this process, but that should not surprise anyone given that it is an <i>astronomical telescope </i> first and foremost. I don't struggle much with the field of view at 480mm plus the crop factor bringing the focal length up to 768mm but one must keep in mind to keep your shutter speeds up. Higher ISO's might be required, but it also doesn't hurt to have a nice, bright morning which I did. And it did help that these birds weren't moving around much. I have to say the '76 subs as a great birding/terrestrial instrument.
<p>
Here are some of the results.

Last year we tried a new spot a little closer to the show at the West Arm of Humber Bay Park. The East Arm would be preferred IF we didn't take quite the production with us. But because we have the means to actually photograph the show closer up, we don't have to go near the crazy-crowds at the CNE or pay a mint for parking as is always the case, never mind actually trying to find a parking spot. Our yearly pilgrimage starts fairly early in the morning as we want to get the best possible view from our location...typically we arrive around 9:30am for a 12:30pm start time...that might sound crazy, but it isn't given that you don't know how the crowds will be, even that far away. Not only that, the weather was gloomy for most of the morning leaving us wondering if the show was actually going to be given the green light.
<p>
To say we bring a "production" is an understatement. We don't pack light.
<p>

Pictured above from right to left, the Tele Vue Pronto and the Tele Vue 76, two Canon 30D's, an older Canon Rebel, two tripods, binculars and lenses, never mind what is not shown, the chairs, a table, food/cooler and the Alinco scanner for listening in.
<p>
We did manage to shoot through the Pronto but we mainly kept that as our visual scope and given it's age and era it was made, it is still delivering a wonderful image. Granted it was
harder to track some of the aircraft at higher speed, but the view was crisp and bright, as expected. False colour? Yeah, but who cares.
<p>
Of course false colour can be a biggy when you photograph so the '76 was called in. Of course that's where the insanity begins.
<p>
Think about it. A 480mm Refractor telescope, with a crop conversion to 768mm with a manual focus trying to capture a fast moving object. Crazy. But it <i>can</i> be done with a lot of practice and patience. Don't expect a high success rate either. I would predict that one out of every two photographs will be a flop. One thing that helped was the Orion Field Flattener to help sharpen the image. For whatever reason, I seem to have an easier time focussing the '76 with it. Perhaps it's my eyes going. I don't know. Of course it will help with the edges, that is for sure. Also it's important to keep the shutter speed up as the '76 is working at f/6.3 and given the weather and haze was having an effect, I will find out how many shots suffered from too slow a shutter, if any actually did.
Overall I found it fun to work with if not quite challenging. A challenge because not only are you trying to do so much at one time including trying to frame it too look nice, the target is moving and at times moving FAST. As aircraft approached our site, I would switch to my 30D and the 70-200 f/2.8 with the 1.4X telenegative to get a different perspective. Both combinations seem to have worked.
<p>
I have a boat load of images to process but check out this first image and I have found what appears to be a smudge on the sensor of my Canon Rebel. Ugh. Anyway, check out this cropped pic, desaturated and a little bit of sepia added of the planes approaching the CN Tower in the background. This was taken with the '76...

<p>
Early results look good.
<p>
I think it is fair to say that both K and I are fortunate indeed with two very good, reasonably portable, multi-functional refractors that again are proving their worth in some very unique circumstances.
<p>
Addendum:
<a href="http://s1198.photobucket.com/user/Tin_Foil_Hat2/library/Air%20Show%202013">The photos are up</a> and are a mixed bag of images where the Canon 70-200mm f/2.8 and 1.4X Telenegative and the Tele Vue 76 were employed. Enjoy!

Well that was me in the early 2000's. I must say that I still really miss that Dob, but I am glad the SP-C6 is back up. Problem that
I had with it was the sled focuser had failed. Basically the pinion gear was completely misaligned with the rack. But after
an adjustment was found on Cloudy Nights (<a href="http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/5566081/Main/5531478">read about that here</a>) I was able
to get the focuser to mesh again. Problem though is that the previous owner might have actually started to strip the small screws I need to tighten. Could
prove to be troublesome in the future.
<P>
Can't find the stock extension tubes though. That's a pain. A Tele Vue 2X Barlow without the lens in it will sub for now...
<P>
And just like the Pronto before it, the weather has turned crummy for the next few nights...figures!

There are quite literally two seasons. StarFest and Christmas never mind construction and hot, humid weather. This year was not quite hot and not quite humid but it wouldn’t be StarFest without a Tornado Warning issued somewhat close to River Place Park. That was Wednesday. Wednesday morning started off with a bang as nasty weather moved through with high winds and rain. Later that afternoon, a funnel cloud was spotted near Arthur, Ontario. Wednesday for whatever cosmic reason, is “Tornado Day”. Arthur, thankfully, is not that close to where we are. Still, it was a tad disconcerting that, once again, a tornado was spotted during StarFest.
<p>
K and I got lucky only because we showed up as it was clearing up. Lots of set up including our trailer, dining tent (Party Central!) and the New Eyes Old Skies vendor tent. So luckily for us the weather cooperated.
<p>
Wednesday night it cleared and we got some observing done. I was working with a 105mm Antares Refractor trying to demonstrate just how faint this particular telescope could see visually by challenging myself to observe some very faint Struve double stars in Aquila. Given the ever encroaching light pollution I did manage to spot a pair down to 12.5 magnitude. Not bad!
<p>
Thursday night really defines StarFest personally for us. Always good times and good fun. Tony and Janet and <a href="http://www.kendrickastro.com/astro/index.html">Jim Kendrick</a> finally showed up along with John and Maggie, Dave, Brent, Drew, K and myself for our annual Thursday night pot luck dinner which is always so much fun. Everyone has become family. I am not sure StarFest would be the same without it. Thankfully, we were all able to get back together, not to mention the usual shenanigans of our music night with Dave, John, Mickey, Victor and someone else I can’t remember. Otherwise it was great fun.
<p>
I cannot honestly remember when we first visited Normand Fullum's monster 36" telescope but it was sure impressive...We didn't get a chance to look through it.
<p>
Friday was the first vendor day and it was lots of fun to see old friends and to make new ones as K and I volunteered to help out Bruce and Susan at the <a href="http://www.neweyesoldskies.com">New Eyes Old Skies</a> tent. Friday was a very nice day till about early afternoon when high altitude clouds began to form. By evening a line of clouds began to form and showers were bearing down on River Place along with some moderate wind. Someone forgot to cover his scope, a wonderful TEC 140 (not to mention any names, right Malcolm?). So we packed everything up, guitars got out again and the “Girls” had their little pow-wow in what we guys have nicknamed “Estrogen Meadows” which is John and Maggie’s tent. Except they kick out John. At midnight it had cleared. I should have gone to bed, but I rolled out the Tele Vue 76 for some deep, wide field observing…
<p>
Saturday was the last of the vendor days as again we volunteered for <a href="http://www.neweyesoldskies.com">New Eyes Old Skies</a> and made a day of it. We believe we generated quite a bit of buzz there and we hope to see all our new friends throughout the years to come. It was also fortunate that Saturday night was THE night at StarFest. Still, I was dead tired but managed to work with my ES127ED to start the Herschel 400 list. This list can be very challenging. However, I stayed mainly in Cassiopeia and some of the wonderful open clusters in that constellation. But by 1am, fatigue was really becoming a factor and K and I crashed for the night.
<p>
Sunday we took everything down and headed out for our annual lunch at “The Spot” restaurant where again our good friends met up to enjoy a good meal, lots of laughs (we were slap happy!) and just to reminisce about StarFests past.
<p>
StarFest can be defined many ways, but I define it as a place to gather, a place of “fellowship under the stars” (not my phrase, that was a StarFest phrase), a place for family. Our “astronomy family”.
<p>
More great memories. And more to come…Check some pics below...

Are you crazy? The short answer to the second question is "yes"...
<p>
Anyway, if the other way of saying "pushing the limits" is "doing something crazy", this might actually apply. Historically and practically the best focal length for bird photography in terms of a small APO refractor or spotting scope is usually about 300-500mm focal length. Same generally goes for lenses. <a href="http://astroshutter.zenfolio.com/">Steve Owen</a>, a great bird photographer, works from a marvelous Canon L lens, the 100-400mm zoom. That makes a lot of sense to me. Any focal length above this is generally reserved for the catadioptric style optical tube. That makes sense too as it is compact to handle such a longer focal length.
<p>
And so goes the thinking until I tried this...

Outdoor Bird Cannon?
<p>
Now, before you start thinking I've lost it (or is it too late for that?) let's take a look at that set up. That's a 127ED Explore Scientific 5" APO with a 952mm focal length on the SkyWatcher AZ4 mount head and a standard tripod. This set up is not too heavy and not too heavy to transport for a <i>short</i> walk. Yes, a SHORT walk. I wouldn't want to hike it. Attached is my Canon 30D DSLR producing a crop factor of 1.6 making the effective focal length 1523mm and you might be surprised about the results. With that sort of focal length getting close to 500 metres or more is possible. But is it practical? Yes and no. I found there were a lot of gremlins working together. First, there was a lot of infrared around as it was bright and sunny and of course that equates to poor seeing at such a distance. Second, I was set up on a wood boardwalk like structure affecting the stability, perhaps that had an effect. Probably the hardest thing was to get focus on moving objects. Birds just don't sit around too long, so that was really tough. The auto-focus 400mm lens has a big advantage over this set up.
<p>
Have a look at some of the results...

One thing that I did learn in the two hours at Rattray Marsh here in Mississauga, is that birds-in-flight is almost next to impossible. It can be done, but there is a lot of blood, sweat and tears to get it. I'd rather leave that to the 400mm crowd.
<p>
In the end, with some more practice, this could be a very nice, stationary set up to work from to compliment my 480mm Tele Vue 76. But there are limits. I would only want to walk a short distance and at the end of this particular session, I had to walk up hill with it. Not fun :)

It feels good to be back in the drivers seat. I have been out of the astronomy-retail world since October and we celebrated a grand opening of New Eyes Old Skies on June 1st 2013.
New Eyes Old Skies offers a unique experience as being the first store in Canada to combine Astronomy and Birding Optics with Eyewear, a complete "Optics Experience". Located in Richmond Hill, it's central location is accessible to just about anyone living in the Greater Toronto Area and not too far a drive for folks in northern York, Durham, Simcoe and Dufferin Counties.

Lake effect clouds (or worse) wreaks all kinds of havoc. I mean lets be honest, Southern Ontario is like one giant penninsula. But when it is clear and you know for sure that the conditions are more than ideal, then maybe the big scope will work...but as you know, when it's clear, it's usually quite chilly to downright freezing (see the first post)<br /><br />M:)Marc Fitkinhttp://www.blogger.com/profile/13759570467599565095noreply@blogger.com4tag:blogger.com,1999:blog-5865036020787364523.post-43049207134007939392010-02-21T20:31:00.002-05:002010-02-21T20:32:16.464-05:00Refractor pic of the day<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgCe2xj0E1ekcyCFLLfrZa5s3lH8w_XKVwZFZHkm9ZrQq6vEoQEKPI4wIVRuqjQS1RPlHNiWzOVA2I7-ULe-YD0tcZVoiUA4m9KBDGh0lCiFjXFI_rj3TI7NDrj1GUr46d2vW4Ot4XY8Ps/s1600-h/21035_477613905354_792160354_11064757_1647339_n.jpg"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;width: 200px; height: 320px;" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgCe2xj0E1ekcyCFLLfrZa5s3lH8w_XKVwZFZHkm9ZrQq6vEoQEKPI4wIVRuqjQS1RPlHNiWzOVA2I7-ULe-YD0tcZVoiUA4m9KBDGh0lCiFjXFI_rj3TI7NDrj1GUr46d2vW4Ot4XY8Ps/s320/21035_477613905354_792160354_11064757_1647339_n.jpg" border="0" alt=""id="BLOGGER_PHOTO_ID_5440874442446303266" /></a><br /><br /><br /><br /><br />I shared this on Cloudy Nights and on Facebook...<br />The old Refractor in Mississauga...just before observing started...Marc Fitkinhttp://www.blogger.com/profile/13759570467599565095noreply@blogger.com2tag:blogger.com,1999:blog-5865036020787364523.post-66143282615644229472010-02-21T20:05:00.009-05:002010-02-22T00:29:40.819-05:00A case for the quick set up...in Winter (or why astronomers should never HIBERNATE!.Just to summarize:<br /><br />I have been looking at double stars...like I normally do. Eta Orionis is fab! Go look at it! Mars has been great. This has been a good opposition. Go look at it! Saturn is back, it's great! Go look at it!<br /><br />So anyway...<br /><br />But what I want to do is talk about the quick set up. I honestly feel today's amateur short changes himself/herself by imposing a moratorium on winter observing because of the usual excuses...it's too cold, the set up takes too long, it's too cold...blah, blah, blah. The question of portability has more involved in it than "can I lift it"...just like picking the right clothing, picking the right telescope is very important.<br /><br />Okay so it might sound more like a "Pronto Brag" (thanks SUG!). But whatever you have, the case for the "quick set up" is this. If it takes too long to set up, takes too long to cool down and quite frankly, is too cold to touch in the dead of winter, chances are you have the wrong "winter scope". This assumes you live in a snowy country (what snow? Toronto has had so little this year). If you are observing in Florida, you might want to skip this blog entry. <br /><br />Any small Refractor, SCT/CAT, 6"-8" Dob or Reflector that can be mounted to a sturdy, portable AZ mount (or EQ if not too big) is desirable. In my case, the Tele Vue Pronto which can be converted to so many different types of observing, it's been a great scope in the quicky set up (assuming I remember to convert it to the right dovetail--side note to that is I merged the universal dovetail to the TV balance plate--that worked!). <br /><br />How fast is the Pronto up? Well, under 10 minutes. I would hazard a guess that I could set up the Pronto in five minutes with heaters and e/p's ready to go. Simple AZ mounting, no motors, no polar alignment, no elaborate GO-TO alignment. Set up fast, to be taken down fast. Oh and the big thing. Short cool down time. Less than 30 minutes on average. You don't know how important that is till you drag out the monster aperture and it cools down after you want to go home.<br /><br />So whatever you do, the quick set up adds to your winter enjoyment. While you don't have the aperture to work with, or perhaps the elaborate, imaging set up, the old argument, "the best telescope is the one you use most often", comes into play. It's far more important that the astronomer is "out looking through equipment" rather than "looking at equipment"....Marc Fitkinhttp://www.blogger.com/profile/13759570467599565095noreply@blogger.com2tag:blogger.com,1999:blog-5865036020787364523.post-60772421000000382032010-01-18T17:09:00.001-05:002010-01-18T17:11:29.714-05:00Mars a (weather) dud?It's happening again...<br /><br />Another opposition full of clouds and well, clouds.

Mars will not be the size of the full Moon! For that stupid email hoax that I get every August since 2003, <a href="http://www.nasa.gov/mission_pages/mars/news/mars-20090609.html">check this out first</a>. <br /><br />What is really happening is Mars is approaching opposition again. Every two years and a bit, Mars will be making it's closest approach to Earth. However, this will not be a close approach like other years, so Mars will be smaller in the telescope. <br /><br />Check this out for lots of information regarding this opposition, <a href="http://seds.org/~spider/spider/Mars/mars2010.html">visit here.</a><br /><br />Last night, among other things, I caught Mars slowly rising in the constellation Cancer after spending a few hours checking out two new double stars and some general observing of M42. Mars was low in the sky when I first spotted it. It's easy to spot because Cancer is a relatively faint constellation. You can't miss it. It will be the brightest "star" in the East after 11pm EST. <br /><br />Visually it was hampered by atmospheric instability so my observations were highly limited but I did make out the polar ice cap quite nicely and some darker features on the surface of the planet. But again, it was very poor seeing. When it gets higher, it will be nicer. <br /><br />One other thing. I don't ever recall looking at Mars through the old Refractor. This is odd because I do remember looking at Mars through other scopes. First time I ever saw it was through my first "real" telescope, a Meade ETX, but after that I cannot recall which scope I was using. I completely missed the 2007 opposition because either the weather stunk, or I was too busy (and the old Refractor was in storage). Oh well, it's all good to go now, so we will just wait for clear skies again.<br /><br />M:)Marc Fitkinhttp://www.blogger.com/profile/13759570467599565095noreply@blogger.com1tag:blogger.com,1999:blog-5865036020787364523.post-61413337392238193122009-11-25T20:08:00.002-05:002009-11-25T20:13:58.312-05:00Cloudy Night Link: Scope Comparison: Celestron C102-HD, FS-102 Takahashi & MK-67 MCTClouded out till further notice.

The original finder is bordering on useless and the stock focuser, while not bad, is badly out of date and very much inflexible. <br /><br />Enter this company: <a href="http://www.focuser.com/">Moonlite Telescope Accessories</a><br /><br />I was fortunate to get a sample to try out. You have to remember it's a risk to take with older scopes because you are never quite sure if it will work, or in this case focus. It is also a two inch upgrade from 1.25". Previous attempts at adapters up sizing the stock focuser to two inch always fail as the eyepiece would be out too far beyond the focal plane. I am pleased to report that after tonight, the Moonlite upgrade, the CF2 with dual rate and a 4.5" travel draw tube with compression rings to handle heavy loads. I will review the Moonlite focuser later. Also because the new focuser accepts standard finder scope mountings, I replaced the stock focuser with an Orion 9X50 RA finder, a BIG improvement.<br /><br />The old Refractor has come along way since it's reactivation. The original SP-C102 is slowly being phased out as new parts go into play. A new tripod, mount, focuser, and finder scope have turned this vintage 80's scope into a 21st century gem of a telescope. Originally slated to be retired when the Pronto showed up, it's <a href="http://thebackyardastronomer.blogspot.com/2009/07/back-in-businesssort-of.html">recent collimation </a>and parts replacement have secured it's place as the proverbial flagship of the telescope fleet. It's better days are not behind it, they are <em>ahead </em>of it.<br /><br />Now, only the OTA needs to be refurbished. When that happens, it will be essentially a new scope. All that would remain from it's former self, are the optics, and that will never change.<br /><br />M:)Marc Fitkinhttp://www.blogger.com/profile/13759570467599565095noreply@blogger.com0
