Bobby,
Thanks. Those are deconvolution artifacts. I usually try to replace the
deconvolved stars with a separate layer (predeconvolved image) but
I was so busy with the rest of the image I sort of neglected to fix the
stars. I'm sure you know what its like....you work so many hours on
an image that I don't even want to see it for a few days <g>.
