NGC 5881 = IC 1100. Dreyer notes that the minute of the 1860 RA should be 4, not 6. This still leaves the NGC position about a minute of time off IC 1100 at 15 05 22.5 +63 10 19, but there is no other reasonable match. The IC position is not too good (Swift again), but the galaxy is a high surface brightness spiral, and the identification is reasonably secure. RC3 and RNGC are incorrect.
Synonyms: H II-818
Discovered in 1789 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "pF, cS, R, vgbM." The Notes to the 1820 'Catalogue of 500 Additional New Nebulae and Clusters of Stars' read "RA in General Catalogue and NGC is 2 min. too great (therefore not found by Bigourdan) . . . The nebula is probably = IC 1100 (Swift IX.), vF, pS, lE."
The RNGC (Sulentic and Tifft 1973) notes that this is a 15.0 mag galaxy. Their coded description reads SLEL,VDIF,LBM,ELNUC.
