Photo of the Week for June 26, 2015
The Hercules globular cluster everyone knows about is M13. It’s a staple of summer evening viewing sessions — and rightly so. M13 is one of the finest deep-sky sights in the northern sky. But Hercules also harbours another very fine globular cluster: M92. Located in the constellation’s northern reaches (roughly 6 degrees north of Pi Herculis), M92 is an easy binocular catch and a fine sight in any telescope.
This wonderful image of the cluster was captured by Guelph, Ontario, astrophotographer Ron Brecher. Ron used a SBIG STL-11000M camera attached to a 10-inch f/6.8 ASA astrographic reflector to acquire the image data. You can view more of his deep-sky photos by visiting his web site.
