NGC 5805. Bob Erdmann points out that this is MCG +08-27-039 (with its declination corrected), a faint double galaxy also mentioned in the UGC Note for N5804, though not called N5805 there. Nor is it noted as a double object in either catalogue, though all the surveys clearly show the fainter companion just to the southeast. This was discovered by Lord Rosse east-southeast of N5804. His sketch shows N5805 as well as N5794, N5797, and N5804 clearly in relation to the 6th mag star mentioned in JH's descriptions for the three brighter galaxies. In spite of the good NGC positions for all four objects, RNGC has unfortunately put the numbers on the wrong galaxies in this field.
The RNGC (Sulentic and Tifft 1973) notes that this is a galaxy. Their coded description reads R,DIF,BM,STELNUC.
Steve Coe, using a 13" f/5.6, notes: "Pretty faint, pretty large, round and brighter in the middle at 135X."
