David this is great if it was taken in our light pollution - is it filtered (why monochrome?). Exposure details? Fast aperture? Alistair

Alistair. Usual Amersham light pollution. No filter but target at zenith. F5.6, ASA 1600, Exps 30, 60 & 120 secs stacked together in DSS. After tweaking in PSP and PS 6 variable colour casts apparent so saturation reduced. David
