Yes Doug.
Apply darks, flats and bias frames (the latter is required if you're scaling your darks). Then, hot and dead pixel removal, this cleans up what the darks may have left behind. Register/align each sub (per channel), then blink them. This is important as it allows you to evaluate the sub quality along with any potential discoveries (we are forever hopeful). Remove the subs that show less desirable features i.e. star FWHM or HFD too high. With the remaining excellent subs, stack/combine them. No an advanced routine, but something that has stuck with me over the journey of imaging.
