Pegasus harbors many galaxies within his borders. Several are quite impressive, including NGC 7331 and NGC 7479. Although NGC 7042 does not spike the "Wow" meter, it's a fun challenge. My drawing was made at 129X with the 10-inch Meade Starfinder Newtonian. The galaxy appears roughly 90" in diameter with an 11th magnitude GSC star 2' to the northeast. Observers with large aperture should try of NGC 7043, an SBa-type galaxy 3'.6 to the northeast. The tight stellar grouping between NGC 7042 and the northern boundary includes 11th through 14th magnitude members. You'll find NGC 7042 about 36' south of 7.7 magnitude HD 202304.
