Object data: Globular
This is yet another astounding view. Even as twilight commenced,
this tight globular was perfect in my suburban skies. Symetrically 
resolved, except in the very center where it was clearly "lumpy" with
unresolved stars touching each other. The super-dense core was strikingly
tighter than other globulars, yet resolution was significant except at the 
very center. In fact, the clump of unresolved central stars, resembled the 
shape of the letter "r", except inverted. (more like an L in my inverted view).
