I settled for -10c and have never had trouble reaching that temp although I have not yet experienced a SEQLD summer while doing astro. In fact, my library of calibration frames are all done at -10c. Note, the 294’s calibration frames (both MC and MM) can look very funky due sensor weirdness. However, they work perfectly if use an ADU of ~30k and 5secs. Alex

Alex, the images I took were at 15 degrees. I have been scared to run them down further as yet. I will work down as I go, I was wondering what temperature do these camera's come down to in our hot summer weather?
