Patrick, Braver man tonight than I! After 4 cavities, a root canal and then learning that a tooth I had worked on a year ago probably has to be pulled on Friday, I decided not to brave the weather tonight. Far too cold for me. Glad you have a silver lining in these cold temps. Another one is the inversion is gone for now. I did go out briefly with some 10x50's, about 20 minutes.

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.
