Details:
Sadly, I only obtained a few frames, in the most light-polluted part of my sky...could do with a lot more!
Details: Fuji S5 Pro camera, ISO 800, 7x 60 seconds, adapted Mamiya 645 80/1.9 lens at f2.8, AstroTrac.
Processing: Deep Sky Stacker used for RAW stacking to a FITS cube...IRAF then used for channel extraction, rotation & cropping, background/gradient subtraction, setting dynamic range limits and colour balance, and RGB recombination.
