The Triangulum Galaxy is a spiral galaxy approximately 3 million light-years from Earth in the constellation Triangulum. It is cataloged as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a nickname it shares with Messier 101. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye.

Triangulum Galaxy M33 Backyard Astrophotography

The Triangulum Galaxy, or Messier 33, is a spiral galaxy in the constellation Triangulum, and is visible to the naked eye under dark sky conditions. Unfortunately, deep sky objects like this are not visible to the unaided eye here in the Coachella Valley due to city light pollution. I was able to capture this on 9-30-16 during the new moon phase, and am very happy with how it turned out.
