M81 - Bode's Galaxy

Bode's Galaxy, Messier 81, is a beautiful and relatively bright galaxy, oriented for us to appreciate its grand spiral design and wonderfully detailed structure. I would have liked to have gotten much more data, but even with a small amount of frames some detail can be seen.

More Details From Wikipedia:
Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a spiral galaxy about 12 million light-years away, in the constellation Ursa Major. Due to its proximity to Earth, large size, and active galactic nucleus (which harbors a 70 million M☉[5] supermassive black hole), Messier 81 has been studied extensively by professional astronomers. The galaxy's large size and relatively high brightness also make it a popular target for amateur astronomers.[6]
