    Another Canuck! -15F is about my limit too.

    The frost gets thick, but the dew heaters perform.

    As an aside about GrandPrixChris note: a benefit of the cold weather is that the deck is frozen solid. Much better than summer. Most of my winter viewing is from there.

    Ha ha , man, you poor guys and the -10, -20 and so on. I think it shows a dedication to your hobby/pastime/ passion/ that I have to applaud. I think about you guys being rooted to the ground at 10 or 11 at night and it just makes me glad it's a rare thing for us to get below 0 degrees C /32F . Oh and Bob, now you mention car photos in the profile made me take a look see and I presume thats what the "my vehicles" tab is for. Cool,When I get back To where my junk is I'll take a few snaps. Couple nice bikes as well.

    Depends on you.The scope has no limits that I am aware of.I am from Canada.I have worked and played in temperatures as low as -55. Its all about how you dress.

    As stated, the scope doesn't care, the electronics do however! As for my personal comfort, 10F is about the limit for any viewing, but this year I added an OBS and have heat so maybe I can drop that limit lower if I am imaging, but if standing at the scope...10F....

    Just came in from -17C (1F). Nice and calm so it was comfortable. Had to get up at 5AM to put the scope outside to be ready by 6:30.

    In addition to the long wait, winter breezes are a big driver for getting an observatory.

    BTW Moon, Saturn and Venus lined up nicely. Mercury hid behind red clouds. Hazy and high-altitude humidity. Still better than the clouds.

    Wow, lots of folks who can take the bitter cold! I'm not at all acclimated to those kinds of temps. The mid-30s F is about my limit, and only if there's no wind...not even the slightest breeze!

    I'm a wimp. 40 to 45 degrees ABOVE zero is about my limit. I guess that comes from living in southern Arizona for the last 30 years. Although the colder weather means that I don't have to deal with snakes.
