There is controversy over which galaxy is really M 102. It could be a duplicate observation of M 101 or it could be this galaxy, NGC 5866. Most modern versions of the Messier catalogue call this one M 102. Sometimes called the Spindle Galaxy, but there are brighter galaxies with the same name which are more worthy of the title.
