Also the reduction of the magenta halos has produced an odd looking halo around the bright stars. I wonder also whether you would consider doing some selective sharpening around the edge of the gas and dust regions. I feel it would make the image pop.

I agree with Paul though. It seems your treatment of magenta halos has left orphan rings around stars which are very distracting in the full res version.

This is my assumption, was done removal before RGB combination.

Thanks colleagues. My problem is as usual colour-blindness. The pic looked fine to me. I swapped the red and green channels, and BLECCHARAMA! I can see what you are talking about. This is going to take some time to fix.

Very best,
