NGC 891 is a fine edge-on spiral with a faint dust lane along its equator.

According to Admiral Smyth, it is another discovery of

Caroline Herschel, who

found it in August, 1783. Her brother William Herschel

cataloged it as H V.19.

Gilbert A. Esquerdo and John C. Barentine have

investigated NGC 891

in the infrared part of the electromagnetic spectrum, and suspect that

this galaxy might have a bar (and thus be of Hubble type SBb) which is not

seen in the visible image because of its edge-on orientation.

NGC 891 is a member of a small group of galaxies, sometimes called the NGC 1023

group, which also contains NGCs 925, 949, 959, 1003, 1023, and 1058 as well as

UGCs 1807, 1865 (DDO 19), 2014 (DDO 22), 2023 (DDO 25), 2034 (DDO 24), and 2259.
