Podcast: Night-sky targets for June 26-July 3, 2009
This week, the Keystone makes a great object for beginning observers, and globular cluster M10, and reflection nebula NGC 6726 provide nice targets for telescope owners.

Each week, Astronomy magazine Senior Editor Michael Bakich, a master at explaining how to observe, posts a podcast about three objects or events you can see in the sky.
Bob and Janice Fera created this image with a Parallax Instruments 12.5-inch Ritchey-Chrétien telescope at f/9 and an SBIG ST-10XE CCD camera. The image is an RGB composite of 15, 15, and 15 minutes, respectively. The images were taken at Mt. Pinos, California on June 28, 2003.
