Image Data

Designation M 10,  NGC 6254,  Bennett 83
Object type Globular cluster
Coordinates 16 h 57 min    - 04° 06'   Ophiuchus (Oph)
Description Messier 10 is a bright (mag. 6.6), very large (15'), round, globular which condenses to a packed core.  A very rich cluster, one of the better ones in the sky, it is located in the rather barren central Opiuchus region located 9.6° E of Yed Posterior (Epsilon Ophiuchi).   Messier, who discovered this fine globular in 1764, failed to see any stars in it, although they are plainly visible in a modern 3" (75mm) telescope.
