Finally shoot 80 bias at 0.001s or the shortest exposure your camera will give you. Then combine them into a master bias.

I'm pretty much at the same begining stage, but thanks marc, it does clarify things.
could you explain light frames as well? are they the actual image frames?
what is ADU? "So if your camera is a 16bit camera, shoot to reach 10k or 20k ADU."
"whatever duration will give you approx 1/3 of your camera full well." is this 1/3rd of the exposure time for the image frames?
also, what are the lightboxes used for? i've seen a few black boxes with white insides at the end of a few scopes at snake valley.
for dark frames, is it acceptable to just cover the ota instead of the camera lens opening?
I've tried my hand with deep sky stacker so far.
