Category: Globular cluster.
Class: 
Constellation: Lyr
Data: mag   size 
Position: RA :  DEC :
Description:
With the RFT and a 22mm Panoptic that give about 40X this compact globular
cluster really swims in the Milky Way.  I saw it as bright, large,
round and much brighter in the middle, an obvious globular even at
low power.  There is a pretty bright star (about 9th mag) on the west
side of the cluster.  Raising the power to 100X with an 8.8mm Meade
UWA will resolve 6 stars at the edge of this cluster.  There is still
a fuzzy central section.  Averted vision will show about 20 more very
faint stars that are at the limit of the 6 inch scope.  These faint
members were never held steady at the higher power.
