Looking at the Antlia images Doug posted below, and comparing with my L- Enhance images, I am struck by the lack of “bloom” around the stars with the Antlia. I have been imaging with 2 different 72mm achromats so I expect some fringe effects but am surprised by the extent of it. I had expected that with the dual band filters, much of this would be avoided. It doesn’t look that way though.

Any tips on Photoshop processing it out?
