Bode's nebula and friends

The Bode's nebula (Messier 81, which is actually a grand spiral galaxy), the Cigar galaxy (Messier 82) and NGC 3077 in a family portrait. Seen around the galaxies, but much closer, is faint dusty wisps from our galaxy the Milky Way, in the form of Integrated Flux Nebula illuminated by all the Milky Way's stars.

 

This image is an enhanced color image, combining "traditional" LRGB data augmented with narrowband Ha, SII and OIII emission bands. I wanted to keep the colors quite natural, so as the narrowband emissions not to overpower the scene.

 

Per channel exposures:

L: 39x10min

R: 33x10min

G: 32x10min

B: 32x10min

Ha: 15x30min

SII: 8x30min

OIII: 7x30min

 

Total integration time 37 hours 40 minutes
