Keep getting little dark spots/patches in the background with this been back over the processing a few times but not sure just when they appear. Next step new flats and darks and see where that takes me.

I've reduced them as much as I can but they're still there....


Hope you like

The reprocess looks much better. I usually find black spots when noise reduction has been too aggressive, and sometimes if you use deconvolution (sharpening).
