For my astroimaging I alway cool the imager to -10. I picked that since going colder doesn't really help with the kind of work I do and because I can achieve that even on hot summer nights so I have consistency through the year. So tonight I opened the observatory and turned on the camera and found it was already at -10. I ran the cooling circuits anyway but tonight it's the ambient air temps doing most of the work cooling the chip. So I guess that's one good the (the only good thing?) about it being so cold. patrick
