Thanks.

If you want to quickly try without mask, start with 6 layers, and check ToLightness and Deringering ..

I merged in a stack of a few 60 second shots to try to mitigate the core brightness, but, yes, I agree it still seems a bit much. I might try the HDRMultiscale you suggest on those 60 second shots before merging. Trying it after the merge seemed to lead to an awful mess.

Thanks. I take no credit though. It was the GradientMerge tool in PixInsight - and a nice tutorial I found somewhere on how to use it well for more than two frames, which was puzzling me. The trick seemed to be to do it a rough one with the old (StarAlignment) tool and then use that to align the images for the new tool!

Not sure if this corresponds tho,, just looks similar ?
I do like your image at full screen level tho, real nice job there

Yes, another member has suggested offline it could be worth a bit more gentle reprocess. I might give that a go.
