TITLE=The Globular Cluster M13

This is approximately the view one gets from about a 10-inch telescope in dark skies. This is the full resolution image, cropped from the larger 6-megapixel 10D frame. Plate scale = 2.1 arc-seconds/pixel. The redder faint stars are an artifact of the strong light pollution from the Denver metro area, where this image was obtained.

500 mm f/4 + 1.4x TC = 700 mm f/5.6, Canon 10D camera at ISO 800. Added eight 15-second exposures made from in the Denver metro area. Faintest star ~ 15.8.
