Photo of the Week #438: Globular Cluster M92
Found in the constellation Hercules, the globular cluster Messier 92 is often overlooked by observers due to its proximity to the nearby larger and brighter cluster M13. About 27,000 light-years distant and glowing at magnitude 7.5, M92 is estimated to contain over 300,000 stars and is one of the premier objects of the summer night sky.
Gord Rife of Schomberg, Ontario, took this image of M92 using an 8-inch f/6.3 Newtonian astrograph equipped with a Baader field flattener. Twelve 10-minute exposures were taken using an SBIG ST-8300C CCD camera.
