I took this 30-second long prime focus image of the great globular cluster M3 in Canes Venatici on 2007/7/30 using a Canon EOS Digital Rebel DSLR camera set at at ISO 1600 and a 14" f/10 Meade LX200GPS SCT. The location was the Astronomical Society of Harrisburg's Naylor Observatory near Lewisberry, Pennsylvania.
