||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.
