NGC 752: Open Cluster (Andromeda) RA: 01h 57.8m / DEC: +37° 51'.0
Instrument: 10-inch Starfinder

The autumn constellation Andromeda is known more for her galaxies than her open star clusters. When looking toward Andromeda, we are gazing over the edge of the Milky Way at the depths of intergalactic space. The great Andromeda galaxy, M31, is among the stellar cities you will find in this region. However, residing this close to the Milky Way means there are plenty of celestial gems plucked from our home galaxy, The Milky Way. NGC 752 is one of these. This 5.7 magnitude open star cluster ranges over a 49' area. Easily visible to the unaided eye as a nebulous glow, NGC 752 is sometimes mistaken as another Local Group galaxy, M33. The sketch at left captures NGC 752's appearance at moderate power (63X) in my 10-inch Starfinder Newtonian. Some 53 stars are spread across the field of view. The brightest members shine at 7th magnitude with the majority falling in around 9th magnitude. You'll find NGC 752 about 4.5 degrees south-southwest of 2.1 magnitude Almaak, Gamma (57) Andromedae.
