Discovered in 1793 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "a large cluster of scattered small stars, iF, considerably rich."
Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "a fine, large, rich, pretty much compressed cluster; irregularly extended, 10' long, 7' broad; stars 12 and 13th mag nearly equal."

The RNGC (Sulentic and Tifft 1973) notes that this is a 8.5 mag open cluster.
Listed by the Herschel Club, described as "some 40 stars, nice small cluster, hard to distinguish, noting nothing special, but loosely scattered. 8-inch, 48x."
Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10M; 8' diameter; fairly large, faint and very rich; 80-plus 11 thru 13M members; 30' SW of 5M Zeta PYX."
Steve Coe, observing with a 13" f/5.6, notes: "Bright, pretty large, pretty rich, pretty compressed, 32 stars of mags 11 to 13 counted at 165X. The backround is lumpy with unresolved stars. There is a nice white and light blue double star on the east side of the cluster."

The cluster NGC 2627 appears irregular, spacious, pretty large, packed with various magnitude stars. The main focus of this cluster is a prominent string of stars clearly divided this cluster in obvious two parts, cut through the group from east to west. The western end of the string is nicely edge with a pair of 10+ magnitude stars. The bulk of the cluster and also the brightest part, are situated towards the north-east and even display a few scattered dark patches between the stars. A smaller section with fainter stars concentrate towards the southern side clearly divided the patchy cluster with a dark lane. Left over stars share space in the far western area. My attention was drawn to the colorful stars in this cluster shading from white into deep yellow.
Location: Pietersburg (South 23 53. East 29 28).
Sky conditions: Good.
Instrument: Meade 12 inch (Eyepiece 40mm).
Date: 25 January 1998.
Field of view: 52.7 arc minutes.
Very much irregular, spacious, pretty large cluster with clearly packed bright and faint stars spread out in a busy field. This cluster clearly divided in two, with a smaller section to the south, to the northeast a larger area with more stars. In a way it resembles a close impression to us.
12-inch f/10 SCT (EP: 2-inch 40mm SW 76x 53' fov; 2-inch 32mm SW 95x 42' fov; 2-inch 14mm UW 218x 23' fov)
Large, loose defined cluster divided into sections (76x). The large, denser area divided in two by a slightly dark line, situated towards the north, with a smaller composition of stars to the south. The third smaller group of stars are scattered west and close to the larger two portions with a relatively bright star imbedded. Approximately 100 loose-standing stars in different sizes, and along with careful observation a combination of different colours from white to golden-yellow can be discerned (218x). The star cluster is slightly elongated, situated between two fairly bright 8th magnitude stars, which are situated in an eastern and western direction. It would seem that my description is in accordance with J Herschel's 10' long 7' broad, stars 12 & 13 magnitude nearly equal according to the " NGC Catalogue".
Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.
This open cluster is well detached which consists of 12th to 13th magnitude stars and that the stars in this cluster is slightly concentrated towards each other.Most of the stars in this cluster are almost as bright as each other.This open cluster has a semi-circular shape which is orientated in an east west direction.This open cluster measures 8.2'x 6.3'with P.A:West/East.
