Description:
Barbara Wilson's Globular Cluster Observations...
SOURCE: Brian Skiff
Second most distant globular in Milky Way (97.9 kpc).  I found it
located just off a star of about 12th mag. No central brightening at
all, very soft round glow.  Faint, but under these incredible skies
not difficult to see.  According to Brian's chart the brightest stars
are 18th mag, horizontal branch magnitude is 20.6. Has been plotted on
several atlases as the Serpens[???] Dwarf. Discoverer: Wilson, Baade
[Just 40' NW of lovely mag 8 Carbon Star HD 100041. -Ed.]
