Yes, I have to do a test without cc and another with cc. The image on the left is without and the right is with, and as you can see with cc I have the donut or ring effect. The photo below has ABE applied to highlight the problem.

I usually use the CLS filter, but also when I don't use any filter I get that halo or reflection in the center of the image, which is not capable of correcting the calibration with flats

hello, i have the same problem, i get a white circle in the middle of my frame light. I am using a baader mpcc mark III and Asi 294 mc pro. Did you get any fix?
