Hope that everyone is looking up to the clear skies, shooting the stars and making wonderful plans for this weekend!
I am learning how to do AP with my new camera (QHY600M), I live in California ( it is about 24C at 9pm ) but I am trying to cool my camera to -15C. It can do! close 100% of capacity but it is here!
The issue I faced is making bias frames at this temperatures it seems that my camera starting to warm if I do a lot of fast frames. I started w/ -15C and went to bed, in the morning I found out that sensor's temp is slowly but steadily had been going up ending with the last frame at -10C. In the same night I did dark frames (240s) there was not such effect. all darks were -15C. I do not think that is is a technical issue of the camera opf any sort its' specs -35C below ambient and it does almost -40C.
My question - if anyone knows if I can add pauses between frames in SGP? so like 1 bais frame and then wait for like 5-10 seconds so cooling system can work. it should help (i guess). I could not find such setting in SGP... does it exist?
Obviously I can decrease sensor temp but at the price of more noise I have no problems with lights and darks (should re-consider flats) and obviously have it with bias frames....
UPD: just tried it again. Sensor temp stabilized at -15C at 68% cooling capacity. after 5 bias frames it became -14.5C so I stopped
