No probs, Andrew. Here are the steps I use in a bit more detail:

Quote:
- Create star mask from NB luminance * strong HDRMT
- Extract CIE L*a*b*
- PixelMath a*: iif(RGB_star_mask>0.1,RGB_star_mask *CIEa(RGB_stars)+(1-RGB_star_mask)*$T,$T)
- PixelMath b*: iif(RGB_star_mask>0.1,RGB_star_mask *CIEb(RGB_stars)+(1-RGB_star_mask)*$T,$T)
- Repeat a couple of times
- Recombine L*a*b*
