M 10 (NGC 6254) -- Globular Cluster in Ophiuchus
The Globular Cluster M10 resides at the center of the constellation Ophiuchus (the Serpent
Holder). This large constellation takes up a large section of the summer night sky. Ophiuchus
is well endowed with globular clusters with well over a dozen within reach of my 155mm
refractor from the light-polluted skies above my observing deck at the house.  M10 is my
favorite Ophiuchus globular.
