Oh yeah! I'm well aware but have experienced colder in the past. 10 minutes working with the computer is about the limit, but I have nice warm tea inside. Right now mount and camera are working well. Transparency is super, seeing is horrid. We'll see what we get.

I'm going to give it a try with my Mach2 in sub-zero F temps. It's brilliantly clear (YAY!) but below zero (Wahh!). I hope my laptop doesn't freeze up on me. Wish me luck.

Testing continues primarily to see where and if the normal temp encoders will fail to operate in sub-zero conditions. So far they work fine but we have not seen -20F yet. Maybe Sunday night - Monday morning. Coldest it's ever been in Northern Illinois is -32F, but haven't seen that in the last 10 years.
