Asi533mc pro flat issues

[Gfischer]

Hi Robin,
Hope you had a wonderful holiday. I’ve been experimenting with different flats for the 533 and the results are better. Last night I was doing eaa and started a stack and the over correction showed up badly in red around image. I then noticed the wb was set to balance rgb with live stack sliders in neutral . I turned wb back to 50/50 and restarted stack no more over correction showed. I’m starting to think maybe the Optolong lquad filter is causing the flat issue. Any way the best flat settings seem to be 20k adu 0 gain, 5 offset, 1 sec exposure wb set to 50/50
