revisited M53 (Halifax)

The Burke-Gaffney Observatory imaged Messier 53, a rather nice globular cluster in Coma Berenices. Another M target I had viewed only once.

globular cluster Messier 53 in luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, GIMP. North is up; east is left.

Wide double star HD 114864 aka S 648 is south-east of the glob. Two equally bright stars. B, to the east-north-east, is very slightly dimmer than A.
