Description

I managed to collect 2.5 hours of Ha through a break in the clouds last week, so reprocessed the 7h of OSC RGB data I had from January last year, adding in The Ha with Bill Blanshan's excellent PixelMath expressions.
Credit to Ollie Aplin (@carefreeastro) for the galaxy name, sums it up well I think.
It is apparently a distant part of the M81 group .... it's 4mn light years away from Bode's galaxy (vs only 8mn LY away from us)
I'm hoping to collect some mono lum data to do a full and proper process at some point
