I was talking about a quick set up
I also want to add that, not only is the cold a factor in your portability, it's about taking a risk. In Ontario this time of year, skies are forecast to be clear but may be less than ideal...SO...you probably don't want to drag that hernia causing scope out when you know that observing might "only be an hour or so"...
Less than ideal is the norm in winter months. 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)
