Description

M10 is one of several bright globular clusters found by Messier in the constellation Ophiuchus.  Smyth in 1844 noted "This noble phenomenon is of a lucid white tint, somewhat attenuated at the margin, and clustering to a blaze in the center."

15,000 light years from Earth, M10 shines with a magnitude of 6.4 and is easily visible in binoculars.
