Description:
This globular cluster is imbeded in a triangle of foreground
stars. While not resolved as easily as M10, even though it is
roughly the same distance, many members are seen. The nucleus
is not well defined, only gradually brightening toward the center.
At 100X the darker background reveals a boundary that is not very
well defined, giving this GC a somewhat irregular shape.
