Bode's and Cigar Galaxies LRGB

[Adam1234]

My latest image - Bode's Galaxy (M81) and the Cigar Galaxy (M82), 12 million light years away in the constellation Ursa Major, taken over several nights at the beginning of April.  Definitely an improvement on last years DSLR attempt (First proper attempt at M81/M82 - Getting Started With Imaging - Stargazers Lounge).

Taken with the ED80 and ASI1600mm pro. 

Integration time: 10.65hr

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

I did take just over 3 hours of Ha as well, but it was quite noisy and I was finding it difficult to add the Ha regions without also adding the noise as well. I may try again at a later point if I manage to get more Ha data. If anyone wants to give it a try I'll post the stacked XISF files.

Lovely image Adam, some great detail at full resolution. I really like the angled framing too.

Definitely worth persevering with the Ha, even with what you have already - perhaps try and bring it into the image in targeted areas - Your ~3+ hours should add more to the jets of M82 and within the arms of M81.

Thanks Geeklee. The Ha definitely added more detail to M82, it just unfortunately added lots of extra noise. I'll keep trying!
