Corwin's Notes

===== NGC 4776 = NGC 4759nw. This is one of a double galaxy that also has two companions. However, there are three NGC numbers for the double: N4759, N4776, and N4778, the latter two from J. Herschel, the former due to WH, d'A, and Tempel. The descriptions make the identifications clear, however: N4759 is noted "double", so N4759nw = N4776, and N4759se = N4778 with a 1 minute RA error for N4776 and 78. The companion 1.0' east-northeast N4778 is almost certainly N4761, and -- with somewhat more doubt as Tempel's positions are often coarse -- the companion 4' south of N4776 is N4764. All this means that RC3 needs to be corrected as follows: PGC 43757 = NGC 4778 = NGC 4759se, PGC 43760 = NGC 4764, and PGC 43768 = NGC 4761. PGC 43754 = NGC 4776 = NGC 4759nw is OK.

Steve's Notes

===== NGC 4776 18" (6/17/06): NGC 4776 = HCG 62B is the northwest component of the striking double system NGC 4759. At 225x it appeared fairly faint but very small, round, 20"-24" diameter. NGC 4761 = HCG 62c lies just 1.3' following. Nearly tangent to the southeast edge is slightly brighter NGC 4778 = HCG 62A, just 28" between centers. 17.5" (4/13/96): NGC 4776 is virtually attached to the northwest edge of NGC 4778 and is slightly fainter smaller, round, 20" diameter, faint stellar nucleus. Mag 9 SAO 139019 is just 1.5' SSW of the pair. 17.5" (5/17/90): the northwest component of this double system appears faint, very small, slightly elongated N-S, bright core. The contact companion NGC 4778 = HCG 62A is attached at the SE end (see notes). Located 2' N of mag 9.1 SAO 139019. Second of four with NGC 4761 1' ENE and NGC 4764 4' S.
