Through March and into April I attempted to image Messier 51 with my Skywatcher ED80 and Atik 314L+ (mono).
I ended up with twenty-six five-minute luminance exposures and nineteen three-minute exposures for each of red, green and blue for a total of a fraction over five hours of imaging time.
This is the processed luminance data, scaled down to half size:
I was pretty pleased with that, but my final colour LRGB image I think needs more work. Partly I suspect it’s because I captured the colour data at 2×2 binning so it needed to be scaled up to match the luminance. Partly it’s my lack of skill at processing. I shall definitely return to this another time…
