The Silver Sliver Galaxy (all night)

NGC 891 is a magnitude 10.8, edge-on spiral galaxy, 30 million light-years away. It's located 3.5 degrees east of the bright star Almach (Gamma Andromedae). Galaxies that are oriented edge-on to Earth appear brighter because their total light output is concentrated into a smaller area. Use averted vision and look for a slash of light with a thickened core and tapered ends 12 arc-minutes in length. Owners of larger aperture telescopes should try to see a narrow, dark dust lane bisecting the galaxy's core and disk.
