Each of the 4 images used to compose the M31 Andromeda Galaxy composite image (the first image you see below) is a 30 minute exposure taken with an SBIG ST2000XCM (ST-2000, single shot color camera) through a Takahashi FS102(NSV), with focal reducer - 612mm @f/6. The 4 individual images were then aligned and combined using Registar 1.07 from Auriga Imaging. Taken 15-SEP-2004 from Cave Creek, Arizona.
