Hi everyone.
I’m have a problem with my Orion core. I’ve taken mostly 300 sec subs plus 20x 10 sec, and 20 x 30. Stacked all 3 groups into 3 stacks registered them, done a very gentle stretch and now I’m trying to do a HDR multiscale transformation to fix the blown core. Unusually this works for me but at the moment I get a bad result no matter how many layers I do.

Anything less than 10 layers gives me a ver rough dug out looking core (see first attachment)
11 or higher blows it out even more (see 2nd attachment).

I’ve tried 2 through to 16 layers masked and unmasked. Any tips?
