NGC891 (also known as Caldwell 23) is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Andromeda. It was discovered by William Herschel on October 6, 1784. The galaxy is a member of the NGC1023 group of galaxies in the Local Supercluster. NGC891 looks as the Milky Way would look like when viewed edge-on and in fact both galaxies are considered very similar in terms of luminosity and size. This picture is a widefield view and clearly shows some of the members of AGC347.
