M81 and M82 are two fairly bright galaxies in the Ursa Major constellation.
These two galaxies are close enough that you can observe both at the same time with almost any telescope.

This image is a two part mosaic taken with an MN190 telescope. There was not much overlap between images so after trimming the edges, the final version still ended up being quite wide. In the smaller versions, most of the excess has been cropped. But the entire field was kept for the full size version above.

M82, the irregular galaxy on the left, photographs very well, even from the city. The Mak-Newt did a good job and picked up more detail than I expected. I also took some H-alpha images to pick up the jets that shoot out of this galaxy. But the exposures were not long enough to show them properly so the Ha data was left out of this one.

M81, the spiral on the right also known as Bodes Galaxy, did not photograph quite so nicely as M82. The blue channel didn't really come through and not a lot of detail is available in the spiral arms. More exposure time would help, but the real answer is a dark sky instead of doing it from the city. But still, for a galaxy image taken from an urban backyard, it could be a lot worse.
