A definite work in progress. This is 8 hours of M33, LRGB. The Triangulum Galaxy, as it is sometimes called, is a spiral galaxy at approximately 3 million light years (ly) distance in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598.  The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, which includes the Milky Way Galaxy, the Andromeda Galaxy and about 30 other smaller galaxies. It is one of the most distant permanent objects that can be viewed with the naked eye. Click on this image for much more detail. This image contains about 90 minutes of h-alpha data to bring out the star forming regions of this galaxy.  This image was taken on September 14-15, 2010, with color frames done after the moonset.
