M109 (5-19-09)

Here is M109, a galaxy said to be 55 million light years away in the direction of the Big Dipper or Ursa Major. In fact, M109 from our line of sight sits right next to one of the stars in the bottom of the dipper. This image is 69x30" with the Atik 16 through the Vixen R135S, unguided on the Tak EM-10, processed in Nebulosity and PS Elements 7. The sky was not quite as good as the night before, but it's always great to be under the stars.

The barred spiral structure of this galaxy looks similar to the recently proposed structure of the Milky Way:

Wow, you are right. They are extremely similar. That's very cool and something I wish I'd said in the original post! Thanks for adding it.
