Pixinsight DBE issues

[labtech1122]

Hi, why is my pixinsight making the image look like this after doing any kind of background extraction? I've tried dynamic and automatic, filled lots of videos and went with loads of different settings but it either doesn't touch the image or it well over does it  (the multiple rings)

Hiya labtech. I don't have experience with this issue, but I have seen it in a post before. The idea seemed to point towards checking the rotation of the flats.

Large circle in my images with a 200PDS which won't calibrate out. https://stargazerslounge.com/topic/406778-large-circle-in-my-images-with-a-200pds-which-wont-calibrate-out/

What do the images look like before DBE. Can you post a before and after. The default settings on ABE can be too aggressive if there is just a simple gradient and can make the image worse.

Try turning this down on ABE.

I've had some success with GraXpert when struggling with PixInsight.  Could be worth a try.  You need to give it a tiff so save the fits header info by dragging the triangle at the bottom of the PI onto the worspace then drag that process icon back onto the image when you read it back in.  Took me a while to twig that one so I didnt loose all the useful info.
