NGC 891

NGC 891 is a classic edge-on galaxy in Andromeda, about 4 degrees east of gamma andromedae. For northern hemisphere observers it is a great favourite, however amongst southern observers it is not so well known as it culminates only about 10 degrees above the horizon.

In the telescope, the galaxy appears as a very thin line of light, a little brighter and wider in the centre. The very prominent dust lane running down the middle of the galaxy was not visible in a 10" telescope under moderately dark skies.
