I have (2) Atik cameras (460EX & 414EX) and after reading this post decided to test the cooling readout.
First, it might be worth mentioning a few days ago I purchased a new laptop with Win10 OS. I had to reload all my astronomy programs, including SGP and the latest ASCOM platform. Once I did that I tried my mount, filterwheel, focuser etc. All but my Atik cameras were recognized. Thinking Win 10 might have a driver problem I headed over to the Atik website and found the core driver package had indeed been updated. After downloading and installing it, SGP picked up the cameras and was able to fully control them.
Today, I tried both cameras again paying attention to the cooling readout. Happily, I can report SGP controls the cooling and displays the correct temperature like it always has.
