Hi, the super quick way is to go to Photoshop, Images, Adjustments, Levels and select the "set gray point" dropper and click the dropper on the red sky glow and most of the glow will be gone.

my effort if you don't mind....

i use Nikon View, i sharpen 3X to amplify the bright spots, this amplifying algorithm is the most fool proof to me.
Remove the red channel , and do your own variable brightness.
there will will get the effects you want.

Hi,
IDAS LPS is very good and very expensive, but I think I'll still get one in the future :)

Anyway, my attempt to remove the sky glow... not that good... still got a lot to learn on image processing

Have a nice day.
