Thanks mike All images in the last few months are 6D not 7D, so can't blame the camera any more

I think there is an element of personal preference involved - The landscape is all red/yellows, the light pollution in the air is yellow ... I'm not sure it should be much more blue without being a false colour?

I'll play some more

You wait until you see my "Volcanic Milky Way" shot coming up

I find it perfect for my Fuji and Nikon cameras but its been a while since I used my Canon.

Hmm, but with CCD work one would typically balance the image so the background is intentionally quite neutral would they not? as opposed to matching a different environmental condition?

Yeap, there's a little green airglow in some of my shots from these nights but not much at all, not compared to my shots out in the wheatbelt a couple of months ago.

yeap.

Greg.

Possibly.

My images have traditionally had a more yellow/red hue and I've put it down to wheatbelt dust. Here I'm not in the wheatbelt but arguably just as red-yellow a environment. However Colin Legg doesn't come up with the same colours as I do, so you could argue I am wrong.

Something I'm keen to do is represent it slightly biased more towards how it actually appears than how we might want it to look. I've never seen psychedelic green air glow or dark blue night sky [edit: never say never. I certainly see less red and more blue night sky's]. They might exist, but normally I see neutral or yellow-red wash over the sky from light pollution and dust

I'll play some more and see what variants people like
