I then make a star mask in order to continue the stretch still reserving plenty of room for later tweaks. Bottom line I think one must treat the stars as one photo and the object of interest as another.

Thanks Peter, fair point. I usually presume other people have some magic up their sleeve in acquiring data to not have problems with things like star bloat, but in reality I should probably allow myself more flexibility in how I process the images and do more masking of stars and the like.
