Discovered on 9 November 1890 by W. F. Denning, this is either a close double galaxy, or a single one with a dark lane crossing its nucleus. I've dug out positions for the northern and southern components, though the one I've chosen to represent the galaxy -- assuming it is a single object -- is a blend from the second Guide Star Catalog.

Note that Denning's RA is about 1 minute of time too large. However, given the nearness to the north pole, this amounts to only 1.8 arcmin, so there is no trouble with the identification.

All of Denning's new nebulae were found in the north circumpolar part of the sky, typically within ten degrees of the pole. Denning, by the way, was primarily known as an observer of meteors, comets, and other solar system objects, but did turn his attention to nebulae now and then.
