I use 1% gain and 65 offset as determined from my bias frames of ~0.001 sec, however each camera is an individual and you need to determine whats best for yours.

Edit:- I forgot to mention, once you have determined your flats for an imaging session you dont chance camera orientation, focus, etc or you have to do new flats for that setup. They are easy to so once you get the hang of it. B dont do what I did and have the scope pointing up with the ligh box balancing on top. Got messed up with the power lead and it came off and hit me on the head. Ouch.
