I live in Southern Alberta (lat 49 deg, 42 min N) and used to go out regardless of temp when I was much younger. Now I limit myself to about - 10 C as I can't tolerate colder than that for long. I used to use a Super C8 with a drive corrector connected to the car battery and had no troubles up to - 30. Then I had to sit in the car and warm up after just setting up. It just became more and more difficult to get out the warm car to observe or photograph, especially manually guiding. Electric socks and gloves helped a little. My later goto mounts like Lxd 55 and EQ6 had handcontroller issues about -15 C - a chemical handwarmer helped them. In the colder weather now I spend in a warm shed imaging with the mount in the cold. I found that a dew zapper wrapped around the motors really helped.
