Hi Brett,
Looks pretty good. Don't forget "dark flat" frames - like dark frames, but matched to the same settings/duration as flat frames.
One thing - 12 dark frames might be a bit few, especially considering they're quite easy to take. If you have too few dark frames, you'll actually
add noise to your final stack.
By the way, if you have dark and dark flat frames identically matched to the light/flat frames, you don't actually need bias frames.
