NGC891 is a small galaxy in Andromeda, positioned at about 4 degrees east of gamma Andromedae. The galaxy is being edge-on with clearly distinguished dust-lane in large telescopes. NGC891 has a length of 13-arc minutes and visual magnitude of about 10, it's fairly hard to detect its spindle shape with naked eyes.
The galaxy can hardly be paid attention because the constellation has a representative object of The Andromeda galaxy (M31) in autumn skies.
