An under-observed globular cluster that is well placed in May, some 10 degrees from Arcturus on the Coma Berenices border. Although 10th magnitude, it has quite low surface brightness and small telescopes generally just show a diffuse glow but it becomes very resolvable to the core with larger instruments as it is a Shapley class X11. It is fairly distant at some 50,000 light-years. Like most of the galactic globulars, it is very old (13.5 Gyr).

Thanks for pointing this one out, Nick. I'm a huge fan of globulars - whatever the density! David
