Doug, you might want to chat to Monte Wilson. He got that sorted out by heating and insulating the OTA tube to keep both ends within a very small temperature differential. Some kind of regulated dew heater system. I think it's working great for him.
Opps. Picture's great by the way.
Nice colors and tracking. Stars a bit overwhelming and soft though due to your focus.

FSQ needs refocusing as you say about every 2C change in temp.
So if a cold change comes through then it'll be off. You can get a temperature compensating robofocus. You train the robofocus software to the scope and its temperature changes and it will adjust automatically.
Greg.
