Discovered by Charles Messier in 1764. M12 was once believed to be an intermediate type between a globular and a dense open cluster. Although it is not as concentrated as most other globular clusters we are usually familiar with, it is now generally classified as a globular. It lies in the direction of the constellation of Ophiuchus at a distance of about 16,000 light years. The apparent diameter of M12 corresponds to about 75 light years. The star colors in this cluster make for a very pleasing image. 1http://www.seds.org/messier/m/m012.html
