What's the best procedure for producing Dark Flats? I'm using MaximDL 5x. Thanks in advance.

Dark flats - not required. No light - or at least there had better not be - so no way to make a flat for a dark. You do need bias frames for darks for read noise, and you may likely need dark frames for the light flats depending on how long you expose and the amount of noise in your camera.

I'm pretty sure he meant the other way around, taking darks for his

flats. As you noted, so long as he keeps the flat exposure under about

30 seconds, a master bias frame for flats is quite sufficient.
