Globular Cluster in Hercules (M13).
Autoguided prime focus photo taken with a Minolta SR-T101 camera mounted on a 203.2mm Meade LX200 Schmidt-Cassegrain Telescope f/6.3using Kodak Supra 400 ASA film with an exposure of 15 minutes at 11:17 PM EDT on August 7, 2002 in Ellenville, NY. Guiding was done with an SBIG ST-4 on a piggyback mounted ETX90 spotting scope. The ETX90 was coupled to the LX200 Schmidt-Cassegrain Telescope using Losmandy rings. This was the first time I used the ETX90 with an ST-4 to guide an exposure through the LX200.
