Having just returned to astro imaging after being out of hobby for 8 years, I am trying to pick up where I left off, and to remember the things that I have forgotten.
Back in the day, I used AA3, AA4, and lastly AA5 I have now upgraded to AA8.
Having moved on from any many years of using CCD cameras, I have now moved to using CMOS. I am told that accurate dark frame are very critical in removing the amp glow/starburst inherent in CMOS cameras, and am advised that a Master Dark Frame must be created from unscaled dark frames.
Can I stack dark frames while keeping then 'as is', unscaled in AA8.

Re: Dark Calibrarion frames
As long as the darks and lights have the same exposure time you will be fine. To scale you would need to take darks with a longer exposure then your lights and a bias frame. There is a separate section in preprocessing that handles dark scaling, just don't use that feature.

Thanks Iver. "To be fore warned, is to be fore armed"
