Yeh looks like registration error to me not in your other images maybe your star saturation technique has just over emphasised the cyan in the glare you mention, hmm?. Anyway, lots of little galaxies in there huh?, great stuff. I noticed that ring galaxy too a little while ago with the Starfire, very cool
