This object is readily found close by and NE of Alpha Com,
below a pretty rectangle of mag 7 stars whose long sides
are oriented NW-SE. M53 was steadily seen less than 1o S
of the NW corner of this rectangle. The little globular
required averted vision, and seemed of uniform dimness.
(See M13 "yardstick" observation for this same night).
