(Description from SkySafari 6 Pro)
Messier 14 (NGC 6402) is a globular cluster in the constellation Ophiuchus. It was discovered by Charles Messier in 1764, and first resolved into stars by William Herschel in 1783.

M 14 is a bit isolated from brighter stars. It is perhaps easiest to find by going 10° east from from M 10. At magnitude 7.6, Messier 14 can be easily observed with binoculars. A medium-sized telescope shows a hint of individual stars, the brightest of which are 14th magnitude. The cluster is decidedly elongated in shape, and appears more like an elliptical galaxy at first glance.

At a distance of about 30,000 light-years, M 14 is about 100 light-years across. It is approaching us at 77 miles per second, and contains several hundred thousand stars. The absolute magnitude of M 14 is -9.12, which corresponds to a total luminosity of 400,000 Suns. So, while M 14 is intrinsically much more luminous than the two other great Ophiuchus globulars (M 10 and M 12), it appears dimmer because of its greater distance.

In 1938, a nova appeared in this globular cluster, but was not discovered until photographic plates from that era were studied in 1964. The nova reached a maximum magnitude of +9.2, over 100 times brighter than the brightest stars in the cluster. Over 70 variable stars are known in M 14; most are of the W Virginis type common in globular clusters.
