The Triangulum Galaxy is a spiral galaxy approximately 3 million light-years from Earth in the constellation Triangulum. It is catalogued 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, which includes our own Milky Way, the Andromeda Galaxy and about 44 other smaller galaxies. It is one of the most distant objects that can be viewed with the naked eye. This image was obtained remotely, from La Jolla, with a 431 mm PlaneWave CDK reflecting telescope at the observatory in Mayhill, NM, USA, at 1:00 AM local time. Post-processing was on Nebulosity and GIMP software.
