M10

Globular cluster M10 lies in the constellation of Ophiuchus. This is a very bright cluster with a central region that appears slightly pear-shaped. It is about 70 light-years in diameter and lies about 16,000 light-years from Earth.

M10 = NGC6254 ( 16h 57.1m -4°06´, 6.6 mag )
Discovered by Messier on May 29, 1764, this impresive globular cluster in Ophiuchus is approx. 14,300 ly away and measures 84 ly across.

Ophiuchus contains several star clusters, such as IC 4665, NGC 6633, M9, M10, M12, M14, M19, M62, and M107, as well as the nebula IC 4603-4604. The unusual galaxy merger remnant NGC 6240 is also in Ophiuchus.

There are six Messier objects in Ophiuchus: M9, M10, M12, M14, M19, and M62 (and one more as well, if you accept M107 as a true Messier). These are all globular clusters.
