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

IC 1459 = IC 5265. This identity was, surprisingly, first suggested by Swift in his list reporting the discovery of IC 5265 and about 40 other nebulae. Nevertheless, Dreyer did not report this, but suggested instead that it might be NGC 7418 (that is about half a degree south, however). Swift's notes about the nebula being "... bet 2 sts p & f; nf of 2" make the identity clear.

Barnard is credited with discovering I1459, but there is no publication given. I don't see the object in any of Barnard's articles in my collection, so I assume that this was a private communication to Dreyer. Thus, I've had no way to check Barnard's position. Whatever the case, that position is 10 seconds too large in RA and 2 arcmin too far north. This may have helped lead Swift and Dreyer somewhat astray -- though Swift's own position is even further off the mark.

The southwestern nebula, by the way, is IC 5264 (which see). These make a striking pair with IC 1459 being one of the brightest objects in the southern sky that JH missed. He could have also easily picked up I5264, so he either missed sweeping the area, or he had one of his very few observing lapses. His observing assistant, John Stone, tells of a time that JH fell asleep and awoke to find the field absolutely blank -- Stone had continued to faithfully move the telescope with the stars until it was pointed at Table Mountain! Perhaps this is a similar incident.

Historical observations

Barnard, E.E

This elliptical galaxy in Grus was discovered by Barnard and described as "Faint, pretty small, cometary, 12th magnitude nucleus."

Finlay, W.H. (1886)

In December 1886 W.H. Finlay confirmed it with the 7-inch Merz refractor at the Royal Observatory, Cape of Good Hope.

Discusses Hardcastle, J.A. (1914) Nebulae seen on the Franklin-Adams plates. MNRAS, 74(8), 699-707.

p47: "Four nebulae were found to have been identified with different numbers by Hardcastle and at Harvard:

NGC 3794 should read NGC 3804

NGC 4208 should read NGC 4212

IC 3026 should read IC 764

IC 5265 should read IC 1459

It is quite possible that others have been erroneously identified, but this cannot be established because Hardcastle's descriptions are too meager."

Modern observations

Bennett, Jack

Bennett observed it with a 5-inch short-focus refractor, including it in his list of cometary objects as number 129B. His coded description refers to the nucleus of the galaxy, which is grouped under "angularly small objects, almost stellar, easily missed in sweeping, faint, seen only with difficulty."

Steve Coe

Steve Coe, observing with a 13" f/5.6, notes: "Pretty bright, pretty large, much brighter in the middle at 100X. Elongated 2 X 1 in PA 90. Has a very faint companion about 8' to the south. The companion galaxy is very faint, pretty small, not brighter in the middle and elongated 1.5 X 1 in PA 90."

Clarke, W.P. (1992)

William P. Clarke (San Diego, California, USA) writes in The Webb Society Nebulae and Clusters Section Report No. 10, July 1992: "Slight oval shape, major/minor axis ratio about 4:3. PA 45 degrees. Stellar nucleus. (21-inch f/20, x140)."

Tom Lorenzin

Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.3M; 1' diameter; faint and small with brighter center; a little tough! 25' to NNE is faint SP GAL I.5269 (13M; 2' x <1' extent); 35' S and a little W is easier SP GAL N7418 (12M; 2' x 1' extent); toughest of the string is 13.3M SP GAL N7421 (1' diameter) 10' S and a little E of N7418; 50' SSE of N7418 is SP GAL I.5273 (12M; 2' x 1' extent); neat string of pearls in the northern reaches of the Crane."

Contemporary observations

Auke Slotegraaf

Stellenbosch; A two-inch refractor does not show this galaxy, which has a catalogued magnitude of 11.3 and measures 3.5' x 3'.

1997 July 07

1997 October 27: Jonkershoek, seeing 3, transparency 3, sky darkness 4, lim.mag. at south pole 6.0 (naked eye), 10.7 (binoculars). 11x80 tripod-mounted. "Faint, elongated glow close east of a small star. Quite remarkable!"

Magda Streicher

(no date)

16-inch f/10 SCT (EP: 2-inch 32mm SW 127x 32' fov; 2-inch 14mm UW 290x 17' fov; 2-inch 8.8mm UW 462x 11' fov)

Very small, faint and slightly round star-like galaxy surrounded by a halo of haziness. Slightly oval to round in a southwest to northeast direction, small in size with a bright centre that is surrounded with a soft haze. The two stars positioned on either side of the galaxy remind one of the constellation Aquila with the galaxy occupying the spot of Altair. Does not reveal itself well against the backdrop of stars. With high power and averted vision I could just distinguish the galaxy IC 5264.

Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.

In this galaxy the galactic nucleus is almost oval which has the smudge of a flatsomed rugby ball and that this galaxy is very faint as a vague smudge of pale greyish light.Around the outskirts of this galaxy some darker areas are noted.This galaxy measures 3.7'x 2.6'.Chart No:143,NSOG,Vol.3.
