Astroart Forum

My RGB stacks in Astroart have started to clip the blackpoint prior to any processing.
Luminance stacks are fine. Trying to understand what the issue is. Any suggestions welcome.

Hello, verify if the dark frames are the correct ones (duration, temperature) of each R,G,B sequence.
As a test, try disabling the option "Remove negative pixels" in Preprocessing.

Thanks for the negative pixels tip. Will try that. Darks all matched ok.
