Photographing The Triangulum Galaxy (Messier 33)
The Triangulum Galaxy (Messier 33) is 2.73 million light years from earth and is about a third of the size of the Andromeda Galaxy (M31), which is 2.5 million light years distant. To bring out more of the detailed structures, I shot this over two nights for almost 12 hours. The high resolution version of this image is available on Astrobin.
