Globular Cluster M56 (NGC 6779), class X, in Lyra.
RA 19:16.6 (h:m); DEC +30:11 (deg:m); Distance 32900 light years
Visual Brightness 8.3 (mag); Apparent Dimension 7.1 (arc min)
M56 is located about half-way between Beta Cygni (Albireo) and Gamma Lyrae. It is one of the less bright Messier globulars, especially lacking the bright core which most globulars have. Nevertheless it is not too difficult to resolve, even at its rather large distance.
