You can always remove the stars, Brett. There are lots of ways to do this but I like to use PixelMath with a star mask: "iif(star_mask>0.1,0,$T)". You can tweak the 0.1 fudge factor to adjust the size of the holes left where the stars were. A convolution blur afterwards will prevent any hard edges.
