Messier 12

M12

The Globular Cluster M12 was first discovered by Charles Messier in 1764. It can be seen with binoculars from a dark sky site, but requires a much larger telescope to see anything more than a fuzzy patch of light. This image was taken with a 6" refractor, but over the course of 5 hours to gather enough light for the image.
