I am processing a two panel mosaic of Andromeda. I have an issue with PMM were the target image presents a dark gradient towards the center (see screnshot) 
I have tried adjusting the various gradient parameters (especially the ones for the target image) without much success. I have had this with the L filter, but i solved it by carefully aligning the black points before stitching it together - now i have it also with the Red filter but aligning the blackpoints doesnt help. Does anyone have tips on how to solve this?
