Not sure if this is the right place for this discussion. Regarding shooting calibration frames (darks, flats, and bias), any hints or ideas as to the best way to takes these Frames? I believe I know the best way for flats (i.e, white t-shirt over the opening of the scope, etc) but what exposure time (1s, 2s, 10s, etc). Regarding darks, I believe they should be on the same exposure time and temp as with the light frames. What about the bias? As I understand, bias do not depend on temp nor time exposure, so are 1 second bias frames adequate? Sorry for all the questions, but calibration frames info is all over the place.
