NGC 891 is also in the constellation of Andromeda.  It is about 18 degrees east of M-31 and 4 degrees west of the open cluster M-34.   You will probably need at least an 8-inch scope to see it visually, but it may be possible in a 6-inch if you have very dark skies.  Visually, it will be just a fuzzy patch of light, which is the central core area.  The surface brightness (14.6) is just too dim to see visually in anything except the largest amateur scopes.  The brighter core region is relatively easy to image, but the outer regions of the arms are very difficult and almost beyond my 8".
