Flat over-correction on RC8?

Hey all,

I seem to have an intermittent issue with my flats where it appears as though the dust spots are getting over-corrected or offset. Has anyone else experienced this before? I've attached two images of what it looks like. This was processed in APP and my setup is:

RC8 + TSFLAT
ASI2600
Baader Moonglow

It's important to note that I don't see these issues on my ED80 and it seems pretty specific to the RC8, matter of fact I think I started getting this issue after adding the corrector.

Any help would be greatly appreciated!

Did you use a flat dark to scale your flats?

I use the CCDT67 for my RC and haven't had much to do with that flattener. I'll do some flats tomorrow and see what I get.

Nah, I've never actually used dark flats before. Do you think they'd help? It's just the same length flat frame but with the cap on right?

I have exactly the same issues here (and flats on my ED80 work perfectly as well).
