M31 - The Andromeda Galaxy
Andromeda galaxy is 2.3 million light years away. This shot was taken
on August 5, 2010 with my new Orion 102mm premium APO refractor under
the relatively dark skies of Dewey, Arizona. This image is the result
of a stack of subs ranging from 3 to 10 minutes in length. The total
imaging time was approximately 75 minutes using my modified Canon Rebel
the Andromeda galaxy is one of the largest known galaxies. It contains
approximately 300 Billion stars spread across 130,000 light years. M31
is about twice as massive as our Milky Way galaxy, and is headed in our
direction at a speed of 185 miles per second. Don't worry, we will all
be gone before it gets here... The image above also shows M32 a dwarf
elliptical galaxy, seen just below and to the left of M31, and M110, an
elliptical galaxy seen above and to the right in this image.
