Hi Frank
Don’t overlook the important process taking calibration frames as well as your image (light) frames when using the camera.
I can only write about my experience with my SBIG ST7 camera whose design and camera control software (CCDSoft) make it reasonably simple to take Dark Frames at the same temperature and duration as my image (light) frames due to the ST7’s regulated cooling.
By the looks of it, the QHY Pro8 also appears to have regulated cooling which should make it a breeze to ensure your Darks are at the same temperature as your images.
Another issue is that I know my (old parallel) SBIG ST7 uses a Kodak chip which produces quite noisy Dark Frames compared to those I have seen from CCD cameras using the Sony chips.
Some imagers appear to get away without the need for Dark Frames when using less noisy cameras and this should allow you to be more productive at the telescope?
This is not a “for or against” about the brand of cameras I have referred to, just some notes about my experiences with the current camera I use and what I would be looking for in a new camera.
Cheers
Dennis
