Please can I validate my RGB + Ha workflow?

If you want to process my Bubble using Hubble Palette, here are my calibrated, star aligned and stacked images of Ha, Oiii and Sii:

I assume you want to try to get rid of the magenta?  I tried a few suggested mixtures to no avail.  The other one from Astrobin has the same problem, but a bit less... perhaps he deconvoluted.  I asked him what he did.

To get rid of most of magneta stars is to use Color Saturation tool. Create a Star Mask and apply to image protecting everything except the stars. Open Color Saturation and drag the whole line to the bottom and apply to the image repeatedly until the stars are white. I know this is crude but better than showing magenta stars but that is a personal preference. The star sizes are not equal in all three NB images making the stars look magneta.

Thanks, I remembered another write up, but it required a longer deviation through CS5:

You are right, you can get rid of the magenta with the color saturation tool.... almost all the magenta in the image is bogus... like green stars.  Hasta la Vista Magenta...
