Thanks for posting this tutorial. I appreciate that the software has been updated since but I'm confused about calibration frames.
Flats, I totally understand. They remove vignetting and dust bunnies. I use a Geoptic flat panel and
I also understand not to bother with bias frames as they can introduce unwanted noise.
Both my astro cams have zero amp glow so I assume taking darks of the same duration as the lights is pointeless but darks flats? The current version of WBPP doesn't seem to know what dark flats are which suprises me. I've tried adding dark flats and it seems to stack them into a master and subtract them from the lights. I've since not bothered with any dark frames at all and just use flats. I hope someone can point me in the right direction because it's becoming very confusing. Guess the question is, should I just use flats?
