The M81 and M82 galaxies are a pair of galaxies located in the constellation, Ursa Major. M81 (Bode’s Galaxy) is a spiral galaxy that lies approximately 11.8 million light-years away, while M82 (The Cigar Galaxy) is an irregular galaxy at roughly the same distance away from Earth.These galaxies have a
gravitational lock on each other and have affected the shape and composition of one another. Between M81 and M82, you’ll find the Integrated Flux Nebula, but this is extremely faint and difficult to photograph. Bode’s Galaxy and the Cigar Galaxy are members of the
M81 Group of galaxies.
I know there it not much details in the shot but it was more of a test of the RGB filters to see how well I had cleaned the dust motes off and it was under a full moon so my exposure time was very limited. 120 second shots was pushing those limits pretty hard. I would like to revisit this again during a New Moon and even perhaps using the SHO Filters.
I have heard it's best to use RGB filters for Galaxies, perhaps someone can post some great info on their experiences with RGB vs SHO filters on Galaxies.
