The only reason for getting a big 20 inch scope like ours is if you really do want to see 200 background galaxies in your image. Otherwise, we're just making things hard for ourselves.
Separating into stars and nebulosity, processing them separately, and then recombining seems to be a very good technique.
Earlier I wrote "What is the advantage of linear dodge over just adding stars to starless, which is what we do?", but I looked up the maths and linear dodge is in fact just exactly that, adding stars to starless. Slowly we learn.
Well done!

Thanks Mike
I tried Screen mode and it was ok but linear dodge definitely is more accurate with re-adding the stars
