THE COLLINDER CATALOG OF OPEN STAR CLUSTERS

An Observer’s Checklist
Edited by Thomas Watson

The Updated and Observer Friendly Rendition of “Collinder’s Catalog of Open Star Clusters” (updated since the first version of this article)

In 2004 a puzzle presented by a star chart notation sent me off on what, for many months, seemed like the proverbial wild goose chase. Persistence and a good deal of luck, however, eventually led me to the solution to the puzzle, and to the creation of this observer’s checklist.

Like many of you, I have a fondness for the Coathanger, a curious and well-named asterism. I first became aware of its existence while using a copy of Dickinson’s Nightwatch as I reacquainted myself with the night sky. Not long afterward I picked up a copy of the 19^th edition of the Norton’s Star Atlas and Reference Handbook and found, where the Coathanger should be, the designation “Cr.399.”   What, I wondered, did the letters “Cr” stand for?   In this age of instant access to all manner of information, I soon learned that the notation referred to a catalog of open star clusters created by a Swedish astronomy graduate student – Per Arne Collinder – for  his 1931 doctoral dissertation. (“On Structural Properties of Open Clusters and Their Spatial Distribution.”)   Web searches and conventional digging around in the library brought limited results. I came across a reference to the fact that Collinder had gone on to become, not an astronomer, but something of an authority on navigation. I also found that many studies of stars and star clusters (to this day) cite Collinder’s dissertation as a reference. He may have become a mystery to amateur astronomers, but his work was obviously of use to someone. Nothing else about this admittedly minor character in the history of astronomy was forthcoming. No copies of Collinder’s dissertation existed in the local university library, so I was unable to see the catalog, much less read the man’s findings with regards to this class of deep sky objects. I’d come to a dead end, my curiosity far from satisfied.

I really hate when that happens.

Astronomy writer Nancy Thomas, in the Winter 2005 issue of Amateur Astronomy magazine, published an essay on Collinder that rekindled my interest in his catalog. Like me, she had been sent on her quest, years ago, by the “Cr.399” notation for the Coathanger. However, she had done substantially better in her efforts to learn about Collinder, coming up with a photocopy of his catalog (reproduced by the US Naval Observatory directly from his dissertation) and an obituary that, when translated, provided a nutshell account of the man’s life. (See “Per Collinder and His Catalog,” by Nancy Thomas; Amateur Astronomy #48, Winter 2005.)   At the end of her essay, Ms. Thomas expressed the hope that amateur astronomers would take up the challenge of using Collinder’s catalog as an observing list. This seemed a vain hope, without a copy of the catalog. I wrote Nancy a letter to congratulate her on her findings, express appreciation for publishing her results, and to say that I would be interested in taking up the challenge if I could trouble her for a copy of the catalog. This, she was most happy to do, and in a couple of weeks a photocopy of it arrived in my mailbox.

To say I was pleased by this turn of events would be an understatement. I studied the catalog and soon came to the realization that, in its original form, the catalog was of little use to the amateur observer. It contained out-dated coordinates, incorrect NGC and IC numbers (often through no fault of the author), and data that was just plain obscure from the perspective of the average backyard observer. The idea occurred to convert this document into a more streamlined form that might appeal to those who have an interest in both astronomy and history, and so I set to work updating the catalog in a spreadsheet. This turned into a larger task than I expected, especially when I set about finding correct NGC numbers for the objects. To accomplish this, and to provide modern coordinate information, I came to rely heavily on the Historically Corrected New General Catalogue  Ver 1.02 (available on line) and the book Star Clusters by Brent A. Archinal and Steven J. Hynes (Willmann-Bell). No observer of deep sky objects should remain unacquainted with these references.

As I was working my way through the process of making the conversion, a chance came my way, in the summer of 2006, to see Collinder’s dissertation in its entirety. A spur of the moment search with Google Scholar, followed up by a call to the folks at the University of Arizona interlibrary loan program, put a copy of the seventy-five year old tome in my hands for a few weeks. It was an interesting read, written as it was in a more personable and human style than we see used in professional science journals and dissertations these days.   Of greatest interest was the collection of notes that followed the catalog, in which Collinder discusses the individual objects he decided to include in his research. Holding that old dissertation in my hands, after trying for so long to find out anything at all about its author, was a very satisfying experience. The search had come full circle.

Although the majority of the open clusters used by Collinder for his research were objects discovered by other observers over the ages, a significant number of these objects were recognized for what they are for the first time by Collinder, himself. It is for this reason, of course, that the “Cr” designation that sent me on my quest remains on star charts today. The catalog as a whole is a catalog in its own right in that it is a compilation of data on a specific class of objects (open clusters) assembled to facilitate a study of the characteristics of those objects. But whatever use Collinder – and those who came after him – made of this catalog, we now have the option, thanks in large part to the detective work of Nancy Thomas, of using this large collection of objects as resource for our enjoyment of the night sky. I hope this version of it does indeed prove to be user friendly enough to guide you to many worthwhile encounters with the open star clusters of the Milky Way galaxy.

Using the Updated Collinder Catalog

As you observe these objects through the eyepiece it might be interesting to keep in mind that Collinder apparently never saw the majority of the clusters he listed directly with his own eyes. Much, if not most, of his work was done using photographic plates taken from a variety of observatories. Because he used this approach, a significant number of the clusters in his catalog are objects out of reach of northern hemisphere observers. That seems fair enough, when you consider that a comparable number are invisible to observers in the south. The checklist has been left in the original order according to each object’s Cr.number, just as Collinder published it, with no attempt made to sort according to the prospective observer’s latitude.

Most of the clusters in the Collinder Catalog are objects suited to telescopes of various sizes. Some require high magnification, others a low power wide field eyepiece. Some are best viewed with binoculars, or even with the naked eye. If nothing else, Collinder’s catalog clearly illustrates that open star clusters represent a highly diverse set of deep sky objects.

The following is an explanation of the column headings of the checklist derived from Collinder’s catalog.

Cr.#

The catalog number assigned by Collinder to each object included in his study.

NGC/Other Cat

Provides connections to the more general resources from which Collinder derived his list of open clusters. Not all of these designations were included in Collinder’s original catalog. They are added here to allow for easier cross referencing with modern resources. In a few cases Collinder got an NGC/IC number wrong, and where the erroneous number might be found in other references, this has been noted. Also, some of his designations, while correct in their time, are seldom used these days. A few of these, such as that for the Coathanger asterism (4-5 Vul)) have been retained as curiosities.

Con

The constellation in which the object is found.

RA and DEC

The celestial coordinates of the objects according to the Historically Corrected New General Catalogue (HCNGC) v1.02. The coordinates listed in Collinder’s dissertation are from the early 1900s and are not reproduced in this checklist. (See original catalog.)

M (v/p)

Estimates of the apparent magnitudes of these clusters, either visual (v) or photographic (p) taken from such sources as NSOG, the SEDS website, and Archinal & Hynes, and The Historically Corrected New General Catalogue (HCNGC) v.1.02. The magnitudes recorded by Collinder often do not agree with modern sources. (See original catalog.)

# Stars

Estimates of the number of stars contained within star clusters, determined by the examination of photographic plates. Most of these counts are by Collinder. Where he did not provide a number one was substituted from other (usually more recent) sources, as indicated by a number in parenthesis. This segregation was done in order to help maintain some sense of what Collinder measured in his work, while still providing useful information to modern observers. Although these numbers can be useful for giving the observer some sense for the cluster’s nature, always bear in mind that the number of stars seen will be strongly influenced by aperture and conditions.

Size '

Modern estimates of angular size  –  in arc minutes  –  taken from sources such as The Historically Corrected New General Catalogue (HCNGC) v.1.02 and The Night Sky Observer’s Guide (NSOG) by Kepple and Sanner.

Class

A classification system used to describe clusters by comparing them to typical and well known clusters as examples. Classifications of this sort from both Collinder and Lundmark (his doctoral advisor) are included in the original catalog, but only Collinder’s assessment (which in the overwhelming majority of cases is the same as Lundmark’s) are used for this list. This system of descriptive classification is included partly for the historical insight it provides into how these objects were seen by the researcher involved, and also because they might offer an aid to the identification of objects when they are found.

• Plei = Pleiades (M45)
• Praes = Praesepe (M44)
• μ Norm = mu Normae Cluster (NGC 6169)
• Glob = resembled a globular cluster
• Chain = string-like asterism
• Neb = appears nebulous, or contains nebulosity
• nl = none listed
• Notes (n) = Useful information that it is hoped provides some clarification of discrepancies between Collinder’s sources and those currently in use.

Notes for Specific Objects

Nearly all the notes below were gleaned from the book Star Clusters by Brent A. Archinal and Steven J. Hynes. Specific references to portions of the book are provided where they seemed especially useful.

1. Cr.8:  Collinder lists as the NGC designation for this cluster the number 281. However, NGC 281 is itself not a cluster, but a reflection nebula. The cluster Collinder studied here is properly designated IC 1590.
2. Cr.21: Asterism.
3. Cr.24 & Cr.25: The Double Cluster
4. Cr.26:  More likely to be found on charts as IC 1805.
5. Cr.32/33/34: Essentially all parts of one complex, IC 1848 per A/H pg 134.
6. Cr. 39: Perseus Moving Cluster/Group (Mel 20).
7. Cr. 41: Often depicted elsewhere as a bright nebula without mention of the loose cluster involved.
8. Cr.50: TMC = Taurus Moving Cluster.
9. Cr. 63: Associated with nebula IC 410.
10. Cr. 69: a.k.a. Lambda Orionis cluster.
11. Cr. 70: Orion belt cluster.
12. Cr. 81: Sometimes erroneously listed as a globular cluster.
13. Cr. 84: The NGC number listed by Collinder is properly assigned to the nebulosity surrounding Cr.84, NOT to the cluster itself (which may not actually be a cluster).
14. Cr. 109 Some references give an erroneous location of 06h 38.4m +01° 11' due to an original error by Collinder.
15. Cr.156:  According to A/H Collinder 156=Mel 72=Cr.467.
16. Cr.182: It is possible that this is not an actual star cluster.
17. Cr.191: The center of a super cluster (A/H p. 137); good binocular object.
18. Cr. 199 and 202:  something of a messy situation, with Cr.202 (Harvard 3) being included as a separate cluster by various authors, but with very different coordinates, even though Harv. 3 is actually “inside” of NGC 2669 (Cr.199); Cr.202 is apparently a central condensation of the larger cluster. (See A/H p. 168)
19. Cr. 206: an open cluster that actually includes a planetary nebula;  A/H argue that the planetary nebula should be given the NGC designation used by Collinder, with the cluster being identified as Cr.206.
20. Cr. 220: In assembling his catalog Collinder incorrectly identified this cluster as NGC 3247, when it was in fact a “new” cluster. Sold himself short. The NGC number is left in the spreadsheet because some references have apparently perpetuated this error.
21. Cr. 221: May not be a true star cluster.
22. Cr. 233 and 234:  Both Collinder entries refer to the eta Carinae star cluster, with 234 applied by Collinder to the southern portion. The entire object is properly known as Trumpler 16.
23. Cr. 239 & 240: Another cluster in a cluster; 239 = NGC 3572, while 240 should be only a Cr. #.
24. Cr. 243 (Tr.19):  Described by Skiff as “not obvious in 0.35 degree field.”
25. Cr. 254: Probably not a true cluster.
26. Cr.257 & 258: Apparently labeled incorrectly some places as Harv. 5 or Hogg 74. (A/H p. 132 for details.)
27. Cr. 264: J. Herschel’s “Jewel Box.”
28. Cr. 265: Probably not a true cluster.
29. Cr. 267: This is actually a globular cluster. (A/H p.237)
30. Cr. 269: Probably not a true cluster.
31. Cr. 283: Probably not a true cluster.
32. Cr. 294: Probably not a true cluster.
33. Cr. 314: According to A/H Collinder was apparently incorrect in identifying this cluster with NGC 6222. No NSOG reference to this cluster under either designation. However, older atlases such as Norton’s 19^th edition show NGC 6222 is the specified position, as does the newer HB Astroatlas. The HCNGC lists NGC 6222 and Cr. 314 as synonymous.
34. Cr. 316: Appears to be superposed on Tr. 24, and may be part of the same cluster.
35. Cr. 328: Collinder and his mentor apparently thought this might be a globular cluster. Later studies have verified that this is indeed the case.
36. Cr. 330: Another globular cluster caught up in Collinder’s survey.
37. Cr. 334 & 335: Duplicate listings; NGC 6374 is not a separate open cluster.
38. Cr. 339: Collinder provides NGC 6393 for this objects, which turns out to be a galaxy in Draco. The coordinates in Collinder’s catalog actually point to an object in Scorpius, and a check of the Historically Corrected New General Catalogue (HCNGC) Ver 1.02 shows NGC 6396 as the correct alias for Cr. 339. Data from the HCNGC has been used in the updated list.
39. Cr. 346: Another misidentified globular cluster.
40. Cr. 364: Another misidentified globular cluster.
41. Cr. 366: This really is, as Collinder and Lundmark believed, a globular cluster.
42. Cr. 368: Another globular cluster, which was not considered certain in Collinder’s time.
43. Cr. 371: The NGC number applied by Collinder is actually a reference to the nebula around the cluster. He discovered the cluster himself, but apparently did not know he was first to make the distinction.
44. Cr. 374: This cluster is embedded within M24.
45. Cr. 377: Cluster associated with M17.
46. Cr. 381: Yet another cluster considered a globular when Collinder assembled his catalog. It’s globular status has since been verified.
47. Cr. 387: May not be a real cluster.
48. Cr. 391: Collinder apparently considered M11 a globular cluster.
49. Cr. 395: A strange “object” that appears to be globular cluster NGC 6717 (Palomar 9) very near IC 4802, an OC along the same line of sight.
50. Cr. 399: The ‘Coathanger’ asterism, which is not a true star cluster.
51. Cr. 404: May be an asterism associated with nebula NGC 6820.
52. Cr. 409: Globular cluster M71.
53. Cr. 414: Was considered a possible globular cluster when Collinder made the catalog.
54. Cr. 416 & 417: Possibly only a part of NGC 6885.
55. Cr. 425: Probably an asterism in a nebulous region.
56. Cr. 426:  It is thought that Collinder’s description of M73 is actually for M72, a globular cluster, and not the object he intended for Cr. 426.
57. Cr. 429: Possible cluster associated with NGC 7023; the NGC number does not actually refer to his cluster.
58. Cr. 456: May not be a true cluster.
59. Cr.458: Another grouping that may not be a real cluster.
60. Cr. 471: Associated with the nebula identified by IC 5146; this number does not apply directly to the cluster.
