IKO - M81 & M82 LRGB+Ha Data Release - August 2021

[Grant]

Our latest released of data from the Ikarus Observatory project - I don't mind sharing that I always find M81 and M82 very hard to process for some reason so I look forward to seeing all your entries and seeing any tips / tricks people have to share.

The small print:

Beyond that, enjoy and have fun!
