    Here in Canada I was lucky enough to go out in -20C (-4F) in Ontario where I live. There was no wind, I have an electric jacket, and I had acclimatized my telescope well. It worked out well and I, without my jacket, am lucky enough to be used to the cold in Northern Ontario. Acclimatize your equipment for a couple hours, keep warm and you will be fine.

    If I am observing with my telescope in the yard, temperature would not be much of an issue. In Alabama, it is rarely below freezing during the day, and almost never below 20 except on the coldest of winter nights, so once I get the thing started taking its own pictures, I can go inside and watch TV for a couple of hours while it does its thing. If however, I need to be outside, then as long as I can stay warm it would not be an issue. With layered clothing, and a plug-in space heater (pointed away from the telescope of course), I could probably stand temps well below freezing. Without 110v for the heater, or some other way to stay warm, then about freezing is my limit.

    I think I went out when it felt like single digit temps (F), anything below 5 and I would rather stay inside and read a sky atlas
