Pegasus (abbr. Peg, gen. Pegasi)
The Winged Horse. Pegasus is a large northern constellation. Alpha, Beta, and Gamma Peg, together with Alpha Andromedae (which was originally Delta Peg), form the Square of Pegasus. The most prominent deep-sky object is the globular cluster M15 (NGC 7078), one of the densest of its type and notable for its many variable stars and pulsars (magnitude 6.3; diameter 12.3'; R.A. 21h 30.0m, Dec. +12° 10'). Binoculars and small telescopes show it as a misty patch; telescopes of at last 15cm aperture resolve individual stars. See below for details of the constellation's brightest stars.
