Depends on your camera. But I use Gain 1 Offset 60 for everything (RGB, Narrowband). With this camera there is absolutely no point pushing the gain. I use 1 but you could use 0. I only use 1 because it gets written into the FITS header and CCDStack chucks a BF if the gain is 0 in the file. Other than that Craig S. says Offset 110 works fine. In my case I try to get the background ADU to 900 or 1000ADU max. Offset 110 gives me too bright backgrounds. But hey, that's my cam. Experiment with yours.
