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

NGC 5043. JH's RA is apparently 30 seconds too large as a cluster matching his description ("Cluster VIII, oblong; 10' x 7', of loose sc sts 11 m") is centered west of his position. Though I make the cluster a bit larger (14 arcmin by 8 arcmin), I have no doubt that this is JH's object.

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 "cluster VIII; oblong; 10' by 7', of loose scattered stars 11th mag."

Published comments

Sulentic & Tifft (1973)

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NOCL) S.

Contemporary observations

1995 May 28

1995-05-28: 11x80.Technopark. 20:15 SAST. Hazy sky, thin clouds. One of Herschel's Doubtfuls; in the vicinity of Beta Crux. I see an elongated patch which lies to the northeast of a star shown on the U2000 chart. Reading off the co-ordinates, the star lies at RA 13h16m, Dec -60 and a bit. The elongated presence runs to the northeast of this star. Estimate of maximum size = 10 arcmin.

1998 February 26

1998-02-26/27, 6-inch f/8.6 Newtonian, Die Boord. 5.6 (naked eye), seeing good. Loose, poor cluster, much elongated. Two 95 mag stars (shown on U429) with fifteen to twenty 11th mag stars scattered over an elongated area 11'x 2' towards north-east. Only a moderately cohesive grouping but I would rather call it a coarse cluster than a mere chance field-star grouping. Sketched with K9, showing the two 95 mag stars also.

OPEN CLUSTER

RA: 13h16m09s DEC: -60o04'25" - Magnitude: 10.3 Size: 12'

Tel: 16" S/C - 127x - 290x - Date: 19 May 2009 - Site: Polokwane 4.9

This cluster looks more like a busy star field. However stars sort of combine into loose strings that reminds me of a wavy impression. The grouping of faint star strings situated in a north-west to south-east direction. One could actually not distinct it from the rest of the star field.

(no date)

NGC 5043 (13h 16m 45s, -60 03.6)

Doubtful Objects Report 4.

Location: Campsite South 23 16 - East 29 26

Telescope: Meade 8" 26mm eyepiece

Extremely busy starfield peppered with mixed magnitude stars. Approximately 30 brighter stars curling irregularly towards the south west in the field of view. Probably just a concentrated starfield.
