Hello everyone,

would anyone have any suggestion as to what I should do about the halos around some of the stars in the attached image (a crop of a larger image). I find that I have these halos around a number of stars, but not all of them. I'm not sure where they are coming from or how to deal with them.

The image was taken with a 12.5" RCOS and Apogee U16M. Processing was limited to dark subtraction, flat fielding, DBE, deconvolution and then LRGB combination.

Any suggestions would be appreciated.
