Historical observations

Dunlop, James (1827)

James Dunlop discovered this object from Paramatta, New South Wales, and included it as No. 360 in his catalogue of 1827. Using a 9-inch f/12 telescope, he recorded it on 5 occassions, describing it as "a pretty large cluster of small stars of mixed magnitudes, about 12' diameter; the stars are considerably congtregated towards the centre, extended south preceding and north following."

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 "the chief star in middle of a most superbly rich and large cluster, 20' at least in diameter, as it much more than fills field; not much compressed in the middle, stars 10..12th mag." On a second occassion he called it "chief double star of a superb cluster, 15' diameter, gradually much compressed in the middle, irregularly round, stars 10...15th mag." His third observation was recorded as "place of a near double star in centre of a superb cluster; very large and rich; composed of equal stars 12th mag, a fine object, Much more than fills field."

Modern observations

Cozens, Glen

Glen Cozens calls this a quite attractive cluster; "an 8-inch will show it as a high concentration of stars against a grainy background."

2016 October 30, Sunday

Location: Night Sky Caravan Farm, Bonnievale.

Date: 2016 Oct 30, Sunday.

Time: 21:26 SAST

Telescope: Little Martin (4-inch f/6.5 Celestron refractor)

19mm Panoptic (35x): A multi-layered, very large, cluster with lots of pretty bright stars and many faint stars scattered amongst them. The faint stars seem round like an evenly illuminated globular cluster, with pretty bright sprinkles all over. There is a bright orange star off to one side - simply beautiful.


Observing from Stellenbosch, 1983, I saw this cluster in a 2-inch refractor at 30x as a large gathering, made up out of faint stars situated off-centre around a double star. The cluster appears mottled, but with averted vision only 1 or 2 stars stand out, but not definitely. It appears rich and well concentrated.


Observing from the 1500 metre plateau of the SAAO observing site in Sutherland, 11x80 binoculars shows this tight compact cluster accompanied by five 3rd mag stars. The cluster and stars with the naked eye make up the brightest part of the southern milky way between Scorpio and Alpha Centauri. The cluster shows on a very rich field as a tight grouping of stars, the majority of which are just not resolvable in 11x80's. Concentrated visions shows about 4 or 5 individual stars. A hasty glance and it turns into a globular cluster. The cluster lies in a most splendid region of the Milky Way, with quite sharply defined dark nebulae surrounding it.

Just over a degree north of the cluster there is a quite well defined dark, roughly oval patch, which does contain some stars, but is clearly far less populous than the surroundings. This dark oval extends for over a degree and lies elongated north-west to south-east. It appears to taper to the south-eastern extremity and then to curve back towards the open cluster, to the cluster's east, where it becomes more prominent as an elongated degree-long, thin, cigar-shaped void lying south-west to north-east. The south-western edge of the dark patch is terminated by a fourth magnitude star. This whole area is a wonderful interplay of diffuse nebulous backgrounds and dark, nearly lightless patches.

1997 September 03

1997 Sept 03: 11x80 tripod-mounted. 23:00 SAST. Jonkershoek. Wow! Very bright, stellar glow, quite round, like a globular cluster immersed within an open cluster. Near the centre is a tight knot of stars with the large rich fringe. Scattered outliers make the borders uncertain.

1998 April 27

1998-04-27/28, 11x80 tripod-mounted binoculars, Die Boord. Seeing average, transparency average, dew. "A large, mottled patch of star light, one star noticed on the eastern edge. While sweeping, it looks like a globular cluster. Has a round, bright nucleus, 9' across, surrounded closely by a faint haze of light.."

1994 March 15

1994-03-15 Die Boord, 6-inch f/8.6 Newtonian, seeing good. Wonderful!! A very attractive cluster. Almost in the centre lies a nice unequal double star, the brightest component is reddish; it is much brighter than the rest of the cluster-stars. The grouping is irregularly scattered, forming many lines or clumps, as seen at 108x with a 20' field.

RA: 16h13m12s - DEC: -54o13'00" - Magnitude: 5.6 - Size: 15'

Tel: 16" S/C - 290x - Date: 29 April 2009 – Polokwane – Vis 5.2+-

What a beautiful bright cluster show itself in full glory. Very lively compact cluster, taking on the shape of a flower, which leaves fold into one another. It is delicate and stringy cluster with a double star to show off the pollen towards the centre. One of the cluster which can be adore and a pleasure to the eye. Even visible with the naked eye in dark skies. I guess it could hold more or less 150 various magnitude stars. Lovely 6.5 magnitude star on the south-west edge and even a planetary in the fringes slightly more south.

12-inch f/10 SCT (76x, 218x)

Approximately 3o south west of NGC 6115 and further into the branches of the Milky Way bring us on target to the showpiece cluster NGC 6067, which shines with a radiant 5 Magnitude. This lovely swarm of about 100 stars in various magnitudes show a strong overwhelming concentrated middle crowded with stars. A few stars swings out from the south western side to give it a slightly elongated impression from NE to SW. Overall a lovely bright cluster outstanding against the background rich field of view which shows up well even in small apertures. Very pleasing to the eye if you allow yourself time to take in the beauty. Its distance is more or less 6,900 light years away with an age of about 80 million years. The very small planetary nebula PK329.5-02.2 is embedded into the southern part of the cluster. Cluster runs out quite thick to the SW and extended in this way for more or less 10'. Between Gamma and Iota One of the top five clusters in the skies.

Location: Selva Bazânica

Time: 21:31

Telescope: GSO 12" dob

Limiting magnitude: 5.5

Sky conditions: clear

Comment: Easy target after having found NGC6087 alongside the iota1 Nor-iota2 Nor-HR6040 star alignment and then, with the smallest magnification available (50x), star-hop roughly 4 deg NNW, where the rich starfield of NGC6067 will make sure you're in the right vicinity.

Some brightness-balanced, tight doubles in it - great for putting your scope's limiting resolving power through its paces!
