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

NGC 4776 = NGC 4759b. 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 N4759A = N4776, and N4759B = 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 4759a, PGC 43760 = NGC 4764, and PGC 43768 = NGC 4761. PGC 43754 = NGC 4776 = NGC 4759b is OK.

Historical observations

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "vF, S, R, vlbM; the preceding of a double nebula." The other object is NGC 4778. John Herschel incorrectly identified this object with H II-559, which is in fact NGC 4759.

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object.

Contemporary observations

Magda Streicher

(no date)

Location: Campsite South 23 16 - East 29 26

Telescope: Meade 8" 26mm eyepiece

Obvious haziness northwards and close to a faint star with a brighter star a few arc minutes further north. Psi Virginis about 25arc minutes to the south.

In my opinion Herschel mistook NGC 4776 for ........NGC 4764 and NGC 4759. As according to my observations NGC 4764 and NGC 4759 appear as a grouping of galaxies, magnitude approximately 12 -14 in the same field of view. I cannot locate NGC 4776 in any of the star atlases available to me, nor does Burnham's make mention of any of the three.

Uranometria 2000.0 does indicate that NGC 4764 & 4759 are extremely close, virtually on top of one another, the exact position indicate Herschel gives the RA & Dec for NGC 4776. Please can anyone help me out?
