Bother with camera calibration
I've been struggling with getting consistent results from my camera's calibration frames. I shot a series of 20 dark frames at 5 minutes each, and when I stacked them, I still got a lot of hot pixels showing up. I know I can manually remove them, but it feels like I should be able to get cleaner data than this. Has anyone else had issues with their calibration frames lately? I'm using a QHY 268M with the latest firmware and software updates. The gain and offset seem fine, but I'm starting to wonder if it's something with the camera itself or my technique. I've tried changing the gain and offset, but that doesn't seem to make a difference. Any suggestions would be appreciated.
