Hi Mabula. Great program! I have somehow set some parameter to an odd value and am now getting this bullseye pattern whenever I use flats. Have you seen this before or have any idea what I changed to cause this?
Thanks for looking at it.

Hi JandaC,
I suspect either someting is missing in your calibration workflow or the flats are simply way off.
Some questions to solve this:
- Did you calibrate the flats with an appropriate masterbias or master(flat)dark?
- Did you calibrate the light frames with an appropriate masterbias or masterdark?
- Can you share sreenshots of an uncalibrated light frame and a flat frame?
Kind regards,
Mabula
