If you are concerned about the colour, try doing a screen layer of an image which is constituted as Ha SII OIII. You will have to be careful with the opacity, but I have found this works to correct star colour, especially when having done a selective colour mask first.

Thanks, Paul. I'm really struggling with the magenta halo thing. Although I regard it as purely cosmetic, I want to get to grips with it. By "screen layer of an image which is constituted as Ha SII OIII" do you mean mapping a copy of the image to R=Ha G=SII B=OIII and then using something like PhotoShop LAYER --> SCREEN to combine with the R=SII G=Ha B=OIII version?

Best,
Mike

Apologies again for the intrusion.
