|NGC 1: Spiral Galaxy (Pegasus) RA: 00h 07.3m / DEC: +27° 42'.4|
Instrument: 10-inch Starfinder
The Great Square of Pegasus harbors many galaxies, including the first object in the New General Catalog (NGC). NGC 1 resides 1.4 degrees south of 2.0 magnitude Alpheratz. With a visual magnitude of 12.8 and a surface brightness of 22.3 magnitudes per square arc second, this faint spiral galaxy lies near threshold of detectability in my 10-inch Newtonian. The sketch at left renders the appearance at 129X. The galaxy is discernible as a faint one arc minute diameter nebulosity near the center of the field. An 11th magnitude GSC star neighbors an arc minute to the north. This star stands at the apex of a triangular arrangement of stars, the brightest of the three falling in at 10th magnitude. Seventeen field stars complete the portrait. NGC 16 resides 24' to the east.
