Carl. This is not a criticism, just an observation. If you look closely at the centre of the brightest stars you will notice the hole punch effect. If your subs don't show this you might need to mask the stars while applying sharpening/detail enhancing/wavelet type applications during post processing. I'm not familiar with PS, so not sure how to apply a star mask. In principle, if you extract the L*/brightness channel, invert it and set as mask, it should protect the stars - but that's a Pixinsight method.
