Thanks James and Trevor.
Frank. I dont change calibration methods other than no flats for NB.
Always apply darks to any sub, and flats to LRGB.
And BTW master flats made from 10 subs is also pretty standard.
Make sure you take darks at a bunch of common light exposure times, say 2,5,10...20mins? at bin 1 and 2, all at the same temp you take lights.
If you take very short flats with a bright scource, you dont need darks for them (very tedious), the noise for exposures of a few seconds is so low it doesnt matter.
CCD stack is the best IMO, but a bit manual. Its well worth reading up the instructions cover to cover. Once you know it, its easy to use.
