M10

Click on image for larger version.

This cluster looks very much like many of the other bright examples in the Messier catalogue. Though often overlooked, this one and M12 are spectacular jewels in the direction of Ophiuchus. From our vantage point we look at these clusters just over (north) of the galactic plane. M10 is estimated to be 16,000 light years away (perhaps 70 light years in diameter).
