March 21, 2020: First M51 in colour

[michael.h.f.wilkinson]

Grabbed 2h of data on M51, using the Meade 6" F/5 and ASI183MC, after struggling with the mount I settled for 60s subs and got a run of 120 of them. Adding 30 darks, 30 bias frames and 60 flats got me this result.

Yes, more data is needed, the background needs noise reduction, and I could perhaps play with chroma a bit. Still, pretty chuffed with this result. Next time, I think I will use 2x2 binning. Though I am not sure how that interferes with the Bayer mask

Nice image, hope you get some more good data to add soon.
