It was just a project for my course so nothing out there.
Others research was published in the age of high well depth CCD where 1,000,000 electrons was required for the 8-20 e- detectors being used with well depths averaging 100,000 e- or more. Getting 1,000,000 electrons with a KAF-16803 is easy because a 50% well depth is 55,000 e- so 18 exposures. Doing it with an ASI1600 is a lot more painful as you need 2,000 exposures at Unity Gain It has 25x less noise though so you can do a respectable amount of exposures.

The most important part of flat fielding though is good calibration. A bad dark flat will destroy your flat fielding no matter how many flats you have
