Thanks Geoff- yes, it certainly does a much better job than I can do manually.

I find wide images (and even deep sky images) often have a green cast. Having done a lot of nightscapes I often see air glow in nightscape images. Sometimes it can be very green. I remember one night there must have been a solar storm because the sky was super green and it showed up very vividly in a nightscape type exposure.

I'm familiar with SCNR, just that I generally don't like using it much if I can avoid it. Perhaps it's just me, but besides the obvious green removal, it does sometimes seem to lose some overall signal in the image.
