I know that this camera can never achieve unity gain but I still cannot decide if it is better to do 300 second subs at gain 0 or 180 second subs at gain 100 with this camera using no filters? My optics are f5.6 and it is a 115mm triplet. Is it better to get as close to unity gain with this camera using the highest dynamic range and full well capacity or is it better to use slightly shorter subs where the HGC kicks in at a much lower noise level with decreased fwc…. or is it a total wash and both settings are basically identical when capturing dark faint objects in a dark sky.
