History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 4470 = NGC 4610, which see. This may also be IC 3281 (which see), but that is extremely unlikely. It is certainly not IC 3417 (which see) -- that is a star 2.3 arcmin north of the galaxy.

Historical observations

William Herschel (c.1784)

Synonyms: H II-018, H II-498

In William Herschel's "Catalogue of One Thousand New Nebulae and Clusters of Stars" he observed an object on 23 January 1784 which he called "Faint, small." This object received the number H II-18. Its identity was for some time questionable, as Herschel mistook M49 for M61, thereby causing quite some confusion. Dreyer writes: "The entry in the Register (Sweep 105) is: 'Preceding M. Messier's 61st Nebula and not far from its parallel is a nebulous star or small nebula; its PD must be about 80 degrees 23 minutes. The time of its entrance not being taken leaves it uncertain so some minutes, but probably it is about 12h 15m." He recorded it on a second occasion ( H II-498) on the night of 28 December 1785 as "Faint, pretty large."

Published comments
