This photo of M31 was taken on August 28, 2003.  As the camera's field of view could not capture the entire galaxy, this photo is a mosaic of four separate photos.  One 3 minute unguided photo was taken of each quadrant around the galaxy's center.  The four photos were then stitched together in Photoshop.  The photos were taken with a Canon EOS D60 digital camera at ISO 1000 through a 10" Schmidt-Newtonian at F4.  The temperature was about 75 degrees and the sky was slightly hazy.  Significant processing in Photoshop was done to remove the skyglow caused by the haze.
