Unbelievable! I guess my premise was correct. Third time's the charm. This most excellent shot of the The Great Globular Cluster M13 in the constellation Hercules was taken on the night of May 26th 2008.
151 x 15 second frames at 1600 ASA, roughly 38 minutes of exposure time.
Look below, I included a before and after shot, just to pinch myself. Incredible. Guess I found the signal, Mr. Universe.
