I dunno what's wrong with some of the original flats Rob, they look like normal flats to me, maybe more donuts than usual, it does need a clean
One files says 2234 image stars and I can pinpoint it ok, but if I manually calibrate that file with the original flat in the mix and pinpoint it, it says 9 image stars and it won't resolve, yet I see hundreds of stars on the screen? Ya got me. I have 87 light files for this thing and almost half wouldn't align. I re did flats tonight and only 5 are failing now. I'll stick it together eventually
I haven't shot it for about 3 or 4years and
last time wasn't real hot, it was off an 8" mirror too. We appear to have come full circle
