Guide Star.
Image taken with a SBIG ST-4 CCD imager/autoguider at the prime focus of an 203.2mm f/6.3 Meade LX200 Schmidt-Cassegrain Telescope. The image was taken at about 1:35 AM on August 11, 2002 in Ellenville, NY. This was the guide star for my photo of M31 taken with a spotting scope piggyback mounted on the LX200.
