Category: Globular cluster.
Constellation: Oph
Data: mag 6.6  size 15.1' Listed
Position: RA 16:57.1  DEC -04 :06
Using a 40mm Plossl at 50X, this globular cluster appears 
about 10' in diameter with a large, bright nucleus. Many 
stars are resolved.
Increasing the magnificaton to 100X by inserting a 2X Barlow 
to darken the background brings out the resolved members so
they appear as jewels sprinkled evenly around the center.
A nice GC.
