Globular star cluster M10 in the constellation Ophiuchus. From my Messier micro-marathon. Don't let the name confuse you—I just felt like being a bit lyrical.

Not only was it shot quickly (there was no other way during the Marathon), but the atmosphere wasn't great and the Moon was breathing down my neck. Posted for the record.
