NGC 1411
MCG-07-08-004
RA 03:38:45
Dec -44°05.3'
Galaxy

h: "bright, round, very suddenly very much brighter in the middle, 20 arcseconds." On a second occasion he called it "bright, round, pretty suddenly much brighter in the middle, 40 arcseconds."

Steve Gottlieb: 13-inch: moderately bright, fairly small, round, bright core. One of farthest southern galaxies easily viewed from Northern California.

G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five brightest members of the NGC 1433 Group, a part of the Dorado Cloud complex, are NGC 1433, NGC 1512, NGC 1448, NGC 1493 & NGC 1411.

A supernova erupted in this galaxy in 1977 (17.0p).

NGC 1433
ESO249-G014
RA 03:42:01
Dec -47°13.3'
Galaxy

Dunlop 426: "a very faint nebula, about 1' diameter, rather elliptical in the parallel of the equator; with a brightish point or condensation of the nebulous matter, a little to the preceding side of the centre."

h: "bright, large, pretty much elongated, suddenly much brighter in the middle; 100 arcseconds long, 60 arcseconds broad" His second observation was recorded as "very bright, large, much elongated, very suddenly very much brighter in the middle to a nucleus = 10th mag star."

Hartung notes: “This nebula is a large faint haze 3’ - 4’ x 2’ in pa 100 deg fading away imperceptibly at the indefinite edges, with a small bright nucleus hardly 20 arcsec across . . 10.5cm shows only this nucleus, hazy and faint.”

Shapley (1935, "A catalogue of 7889 external galaxies in the Horologium and surrounding regions" Ann.Harv.Coll.Obs. 88, No. 5, 107) notes that "earlier descriptions differ appreciably from the probably more dependable descriptions from the Bruce photographic plates . . . NGC 1433: Not much elongated."
Bergwall et.al. (1978, Astron. Astrophys. Suppl. 33, 243-255) gives this galaxy's B-magnitude in the Johnson system as 10.8. They remark: "Large number of H II regions in ring and in spiral arms."
G. de Vaucouleurs ("Galaxies and the Universe", Chapter 14 - Nearby Groups of Galaxies) notes that the five brightest members of the NGC 1433 Group, a part of the Dorado Cloud complex, are NGC 1433, NGC 1512, NGC 1448, NGC 1493 & NGC 1411.
This galaxy is listed in the "Third Reference Catalogue of Bright Galaxies" as having an outer ring of 5.80 arcminute diameter.

A supernova erupted in this galaxy in 1985 (13.5v).

NGC 1448
MCG-07-08-005
RA 03:44:31
Dec -44°38.6'
Galaxy

h: "pB, vL, vmE, 3' long, 20 arcseconds broad, position = 221.6 degrees."

Hartung notes: “In a field of scattered stars this long narrow nebula is not bright; it appears about 5’ x 0.5’ in pa 40 deg and rises in brightness considerably to the central axis but needs close attention to see its length. 15cm will give the shape faintly.”

NGC 1483
ESO201-G007
RA 03:52:47
Dec -47°28.7'
Galaxy

This galaxy has been cross-referenced with Dunlop 427, and was observed by John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He described it as "pretty faint; round; very little brighter in the middle; 20" across. (Newly polished mirror, but the sky dull and haze forming; so that this may very possibly be Dunlop 428.)" His second description notes is as "very faint; pretty large; round; very gradually a little brighter in the middle; 80" across. I feel convinced that this nebula is too faint to have been seen by Mr Dunlop. Put on the 9 inch aperture, could not discern the least trace of it. Mirror polished yesterday and in high beauty. Sky superb."

James Dunlop observed from Paramatta, New South Wales, using a 9-inch f/12 telescope. His No. 427 is described as "a pretty large nebula, round figure, 2' or 3' diameter." No.428 is recorded as "an extremely faint ill-defined small nebula. A pretty large nebula precedes this."

ESO201-SC?010 Arp-Madore 1 RA 03:55:02 Dec -49°36.9' Globular cluster

NGC 1487
MCG-07-09-002
RA 03:55:46
Dec -42°21.3'
Galaxy

h: "pB, pL, R, 90 arcseconds; makes a triangle with two stars 13th mag about 1 radius of nebula (by diagram) from its edge." On a second occassion he called it "pB, R, gbM, 2'; has two stars 12th mag near it." His third observation was recorded as "pB, R, 2', near a star."

Aguero (1971, Pub. Astron. Soc. Pacific, Vol 83) includes this galaxy in his list of "Interesting Southern Galaxies." He estimates the photographic magnitude at 12.5, and gives the size as 2.1' x 1.3'.

NGC 1493
ESO249-G033
RA 03:57:26
Dec -46°12.6'
Galaxy

This galaxy has been cross-referenced with Dunlop 438, and was observed by John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, vL, R, vglbM, 3'; sky dull, a haze forming." On a second occassion he wrote: "faint; large; round; very gradually a little brighter in the middle; 2.5' across. With 9 inches aperture, and a mirror newly polished yesterday, and in high beauty, it is barely possible to discern with the utmost attention that this nebula exists; but to have discovered it with that aperture and power 180 would have been quite out of the question; possibly, however, 90 might show it better."

Dunlop 438 is described as "a very faint nebula, about 1' diameter, round figure."

NGC 1494 ESO201-G012 RA 03:57:42 Dec -48°54.5' Galaxy	h: "F, L, R, vgvlbM, 70 arcseconds." On a second occassion he called it "F, L, R, vglbM, 2.5'; has north of it a triangle of stars 12th mag."

NGC 1512
MCG-07-09-007
RA 04:03:56
Dec -43°19.8'
Galaxy

Dunlop 466 "a small faint round nebula, about 25 arcseconds diameter, a little brighter in the centre: a star of 10th or 12th magnitude preceding the nebula."

h: "bright, large, slightly elongated, pretty suddenly brighter in the middle, 3' diameter; it is just north of a great group of large stars 6, 7 and 8th mag, scattered over two or three fields." On a second occasion he called it "bright, pretty large, round, 3' diameter. Resolved into stars barely perceptible."

(See also the entry for NGC 1510). The NGC calls it a globular cluster, that is bright, considerably large, round, brighter in the middle, and resolved into stars. Stewart, examining photographic plates, says that it is not a globular cluster, but an "extremely faint ring nebula."

Steve Gottlieb, 13-inch: faint, small, slightly elongated. Forms a pair with N1510 5' SW. Very far south for viewing from Northern California.

The RNGC (Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads SB,BM,DIFARMS&BAR DKLNS.

8-inch Meade, 53’ fov: Extremely faint, small galaxy. Just about a shadow of light, brighter to the middle, and nestled in a delicate starfield. Close to NGC 1510. [MS]

NGC 1527 ESO201-G020 RA 04:08:23 Dec -47°53.8' Galaxy	h: "B, E, spmbM, growing more round internally; 60 arcseconds long, 30 arcseconds broad; pos 77 degrees." On a second occassion he called it "pB, E, vsbM to a roundish nucleus." His third observation was recorded as "pB, pmE, vsvmbM; seen in sweeping in vain for Dunlop 409." Herschel tentatively suggested that this object corresponds with Dunlop 409, which is described as "a very small and very faint round nebula, about 20 arcseconds diameter."

IC 2035 ESO250-G007 RA 04:09:01 Dec -45°31.1' Galaxy	This elliptical galaxy was discovered in 1898 by R.T.A. Inness using the 7-inch Merz refractor at the Royal Observatory, Cape of Good Hope. He described it as "equal to 9.8 mag, round, 10 arcseconds diameter, near CPD -45 403".
