Hi Logan, there is very little need to increase the gain on these cameras. I keep it to 1 not 0 because CCDStack doesn't like FITS files with a 0 gain. Set the offset so your skycount (ADU) in your subs so it's very close to the pedestal of your darks or bias frames. Mine is around 950 ADU so I set the offset to 60 that gives me that same value in my subs in the dark parts. That may vary from camera to camera. Just find the sweet spot for yours. From memory the higher the offset the higher the background ADU in your light subs. Don't remember really I haven't changed those settings in years.
