Hello all,
I am processing some data I collected on the Tadpole Nebula in Deep Sky Stacker, and got a surprising--and distressing result! The entire image is suffused with a blocky quilt pattern. (See attachment, which is slightly stretched but otherwise not post-processed.)
Does anyone have any ideas on what caused this problem and how I can solve it?
Many thanks!
