Globular Cluster in Ophiuchus

View larger image

Messier 14 is one of several prominent globular clusters in the constellation Ophiuchus. It was discovered by Charles Messier in 1764. It is about one magnitude dimmer and slightly smaller than both Messier 10 and Messier 12, two other globulars that can be found a few degrees to its east. It is also farther away than these two, and its stars are dimmer and a bit harder to resolve in a medium-sized telescope. High magnification helps to see the individual stars in its core.
