You often have a sprinkling of green stars. Keep in mind airglow in an otherwise totally dark sky can give green light pollution. Some nights it can be quite intense. See this nightscape:

That green is not accentuated and was real. That was the greenest night I have seen. I did not know the sky was often green until I started doing nightscapes. Now I see it more often than I don't.

It often confused me how come I was getting excess green in some images despite imaging in a near zero light pollution site. Airglow was the answer.

HALVG is a free plugin for Photoshop and is a Photoshop version of SCNR noise reduction tool in PixInsight. It gets rid of the excess green and makes it way easier to balance the colour.

Thanks for the thoughtful comments and the gorgeous green light pollution image.

Because I'm colourblind, I've just written an automatic green star finder. You were right: it found 'em. Things will be under control shortly!

Thanks Paul, that's encouraging.
