NGC 891: Edge-on Spiral Galaxy (Andromeda) RA: 02h 22.6m / DEC: +42° 21'.1
Instrument: 10-inch Starfinder

NGC 891 is an elusive edge-on galaxy in Andromeda. It has a total visual magnitude of 9.9 but a moderately low 22.4 magnitude per square arc second surface brightness. NGC 891 is often detectable in moderate aperture, but only when observing conditions are at their best will this galaxy show detail. My drawing was made at 63X when seeing and transparency conspired to offer a fabulous view in the 10-inch Starfinder Newtonian. The galaxy is spread over a 12'x2' area with a dark dust lane visible across the central portion. The bright star to the northwest shines at 9th magnitude. NGC 891 can be found 3.4 degrees east of 2.1 magnitude Almaak.
