The problem is that you cannot use bias on a CMOS camera. Any exposure
less than 3 seconds is not advisable (not an engineer so not sure why).
So if you cannot use a bias frame on your flats you have to use flat
darks.
I don't understand what's magic about 3 seconds. ZWO specifies an exposure range of 32μs-2000s for the '1600 and the '294. I have seen no issues with flats exposed for less than 1 second with my '1600.
