AN ALTOGETHER MORE INTERESTING map than its neighbour, U464.

The hind-quarters of the Chamaeleon takes up the largest portion of this far-southern chart, on which quite a number of brighter stars and several interesting deepsky objects may be found.

FEATURED OBJECTS: NGC 3149, IC 2596, NGC 3059, NGC 2915, ESO037-SC001, IC 2631, ESO037-EN006, NGC 3195, PK295-13.01.

NGC 3149
ESO019-G001
RA 10:03:45
Dec -80° 25.3'
Galaxy

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, lE, vlbM, 25 arcseconds, has a star 15th mag in it, excentric."

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

Galaxy

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "faint, large, irregularly round, gradually a little brighter in the middle, 3' across, many very small stars near and in it."

Burnham calls it a 12.1 magnitude barred spiral galaxy in Carina, measuring 2.9' x 2.6'.

Bergwall et.al. (1978, Astron. Astrophys. Suppl. 33, 243-255) gives this galaxy's B-magnitude in the Johnson system as 12.2.

A photograph may be found in the Rev. Shapley-Ames Cat.of Bright Gal. (Sandage,Tammann 1981) p107.

NGC 2915
ESO037-G003
RA 09:26:10
Dec -76° 37.6'
Galaxy

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pF, pL, R, gbM, 45 arcseconds."

Bergwall et.al. (1978, Astron. Astrophys. Suppl. 33, 243-255) gives this galaxy's B-magnitude in the Johnson system as 14.1.

This galaxy is included in a sample of galaxies with velocity less than 500km/s with respect to the centroid of the Local Group. (“Nearby Galaxies” Schmidt K.-H., Priebe A., Boller T. (Astron. Nachr. 314, 371 (1993)). Data: Inclination (face-on, in degrees) 53

Planetary nebula

Discovered by h, who recorded it as "planetary nebula, pretty bright, not quite uniform in its light, having two brighter patches, slightly elongated towards a star A; slightly hazy; diameter = 15 or 18 arcsec (in RA 13 seconds of time). Pos of star A = 265.7 , dist = 0.7 diam from edge, 11th mag.; star C pos = 210.7 , dist = 1.75 diam from edge (NB 13 seconds in time = 33.75 arcsec in arc)." His second observation recorded it as "Planetary nebula, round or very slightly elongated; a very little hazy at the edges but still pretty well defined with 240 power. Viewed long and with much attention, being a very remarkable object. I am positive of the existence of two brighter portions near the edges. Companion stars A = 11th mag, pos = 274.7 ; star B = 13th mag, pos = 271.5 ; star C = 14th mag; 204.8 . The star A precedes the centre 14 seconds, which is also the diameter in RA of neb."

Hartung calls it "round, about 30 arcsec across, even in light and bluish with a single prism image. The field is scattered with stars on a very faint ground, four of them being near the nebula. It is clear when once seen with a 3-inch."

Sanford notes that it is "38 arcseconds in diameter but at magnitude 12 requires a telescope with at least a 4-inch aperture to be appreciated."

ASV Journal Vol 24 No 3 June 1971: "faint, small, round and blue in 12.5-inch 150x."

6-inch f/8.6 Newtonian: In low-power (42x, 50’) sweeper, the image of the planetary blurs into that of a small star to its north-west, resulting in a small, mottled faint nebulous glow, the star popping into view now and then. Easy in sweeper with attention. At higher powers, nebula and star(s) clearly separated, the planetary appearing as a small (about 50 arcsec) round glow, quite faint, no detail or colour visible. North-west is a small star (10.5), and straight on is a fainter one (11). West of the nebula is another 11th mag one. (rough sketch made in obs notes).
