Globular cluster M22 in Sagittarius

A map of the star field. Magnitudes are given without a decimal point, e.g. 67 is to be interpreted as magnitude 6.7.

Comments
For the northern-hemisphere observer in a light-polluted area, this is the only globular cluster that could honestly be described as easy to observe with binoculars. I was even able to pick it out during a full moon (albeit from a semi-rural location). Compared to M3, it's half a magnitude brighter and in a much easier place to locate.
Data
RA=18 36, dec=-23 54
