Description:
Very small at 30x and easier to starhop from M27. Dim and looked like a tight
OC (perhaps reminiscent of M11 only not as impressive). 2 stars to the east
and 1 star to the west form sort of a triangle around the GC. 6 stars seen in
the core at 60x. Irregular shape detected at 110x with approx. 10 stars in the
core, loose GC. Rectangular area north of GC devoid of stars. Dimmer at 176x
with approx. 20 stars detected with averted vision. Dimmer at 220x but stars
in the core now more distinct.
