Messier 81 is a beautiful spiral galaxy, one of the nearest to us. At magnitude 6.8, it is fairly easy to see with binoculars, but all that can be seen is a faint oval patch of light. Even through very large telescopes, the intricate details in this photograph cannot be seen visually. However, with a low-power eyepiece, the nearby galaxy Messier 82 can be seen in the same field of view, making this one of the most impressive galaxy pairs visible through amateur telescopes.

The small blue patch to the left of M81 is a nearby dwarf irregular galaxy, Holmberg IX.
