    Description: Wholesale changes to treatment of background, star color, core color and detail on outer rims.

    E

    Description: Tint adjustment to halo which tended yellow/green I didn't prefer.

    F

    Description: I'm done. Really. Just a bump in exposure which I reduced to much last time. Be well.

    H

    Description: Punched contrast to enhance apparent sharpness at normal view sizes (at the expense of some of the halo)
