Historical observations

Dunlop, James (1827)

This cluster was discovered by Dunlop, Number 412 in his catalogue of southern nebulae.

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 "a pretty rich loose large, roundish cluster of stasr 12..14th mag, 7' diameter, not m comp M." On a second occassion he called it "VII class, rich, L, gradually a little compressed in the middle, irregularly round, 12', stars 13,14,15th mag, nearly fills field."

Modern observations

Bennett, Jack

Bennett observed it with a 5-inch short-focus refractor, including it in his list of cometary objects as number 76. His coded description describes it as irregular extended object which is fully of partially resolved into stars under a higher magnification.

1997 May 02

10x50 tripod-mounted, 1997-05-02 (clear skies, no light pollution on horizon, dew on binocs): bright, 4 noticeable stars suround cluster in mensa shape, 15' wide with 1 star resolved in the cluster [RH]

Contemporary observations

Auke Slotegraaf


A two-inch refractor at 20x shows it as a nebulous patch, apparently on the verge of resolution. The cluster appears irregularly round, which possibly reflects the almost resolvability of the stars; although at higher powers (up to 45x), with the resulting increase in contrast, individual stars still cannot be seen. The cluster lies in an asterism of four prominent stars shown on the Uranometria 2000.0 chart. It is easy to locate, because the sourthern tip of the cluster is marked by a 9-10th magnitude star, and with the slightest of averted vision, the cluster is prominent.


In 11x80 binoculars, this open cluster is seen as an irregular misty patch of light.

1997 September 03

1997 Sept 03: 11x80 tripod-mounted. 23:00 SAST. Jonkershoek. Neat! A round mist of light, 5 arcmin across, showing only a single 9.5 mag star in the south-eastern edge. Looks like a globular.

1998 April 23

1998-04-23/24, 11x80 tripod-mounted binoculars, Die Boord. Seeing good, transparency below average, dew. "F, L (6.5'), R nebula with a star on the south-east edge. Of a soft, even light, with no concentration across the surface. Whilst sweeping for it, took it be a globular cluster. Three 8.5 mag field stars to the W, SW and S frame it nicely."

Magda Streicher

1997 April

Location: Camp Site: ( South 23 16 East 29 26 )

Sky conditions: clear fair about 6 magnitude.

Instrument: 8 inch Meade ( super wide-angle 18 mm. Eyepiece ).

Date: April 1997.

Pretty, packed, large round open cluster spread out loosely to merge with the stars in the field. Nice ring of stars to the edge.

(no date)

12-inch f/10 SCT (EP: 2-inch 32mm SW 95x 42' fov; 2-inch 14mm UW 218x 23' fov)

Stars are evenly separated, forming strings that merge with the field stars. The cluster is reasonably bright, round in shape and dark lanes can be seen in between this loose cluster. At the south end is a very lovely blue-white star of 6th magnitude along with a faint string of stars in a half moon shape. Here and there stars appear as double embedded into the cluster. Hogg 19 is situated 10' arc min. to the east and display only a few faint 11 magnitude stars relatively close together. In this case it surely looks like an extension of Bennett 76 (NGC 6134). (Mag 7.2; size 8.0'. )

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

Instrument:12-inch Dobsonian.

This open cluster in appearance takes the form of an irregular circular-like shape whereby I have noticed that the stars in NGC 6134 are strongly concentrated towards each other.This cluster consists of 10th to 11th magnitude stars being clearly resolved.This open cluster measures 10'x 7.6'.
