M81 & M82 with added Ha

[Adam1234]

Here's a reprocess of M81 & M82 from last year. I've managed to add in the Ha data to highlight the Ha regions this time. It was difficult to do without adding in the noise from the Ha, but I managed it with use of some masks. 

L = 435 x 40s (4.83hr), R = 112 x 60s (1.87hr), G = 117 x 60s (1.95hr), B = 120 x 60s (2hr), Ha = ~3hr of 300s

Cracking image, they are both great but I love your M81, so much detail 👍

That's pretty awesome - did you take that with the 80ED?
I've tried my luck on this pair, but from London I only have NB data in SHO and I haven't managed to process that in a way
that looks quite right to me.

Thanks! - yes it was with the ED80.  With galaxies i imagine you would probably struggle to get them to right with with SHO.
