    This is how the print looks. I'm not sure if the purple sky is because of photo lab adjustements or a real effect, but it looks nice.

    Likely it's light pollution. This is, what, about an hour long exposure? It would be a fairly weak light source, probably can't even see it in real-time.

    Nice shot BTW! :)

    Looks like sodium lights with the orange glow, wouldnÂ’t take many on a humid night. Great shot though!

    Around 20-30 minutes, @ f5.6 or so, 200 ISO film. Taken in Kannanaskis at the university field station, with the glow on the trees provided by the building sodium vapour lights.

    As for light pollution in the sky, there aren't any cities to the south (the direction I was facing) until you get into the USA, probably 800 kilometers away at least. Maybe some farmland and small towns though.

    Thanks for the comments!

    In a TV documentary on astrology I learned only the other day that in our industrialised countries we can hardly avoid light pollution any longer, and even where they (now that goes with the programme I saw) built their huge parabol(ic?) antennae to watch the night sky in absolutely rural areas with no villages nor towns around for miles, to they get light pollution these days - and only a long exposure will make it come out. (A couple of farms, no more, do it.) Otherwise the night would seem pitch dark to the researchers' eyes. So the same may apply to your photo (which otherwise is STUNNING).
