Update: deep sky objects in old catalogues

Introduction

The article "Non-stellar objects in old star catalogues" (Paper 1), which appeared in MNASSA in 2003, presented a list of co-ordinates, culled from old star catalogues, where comments or footnotes in the catalogues indicated the (visual) observers had noticed an unknown object in the vicinity of the stars they were measuring as part of their pioneering astrometric work.

The 30 catalogues I scrutinized were published between 1752 and 1917, and were compiled by experienced observers. I reasoned it was possible that they may have noticed objects overlooked by other observers (Sir John Herschel comes to mind) since their methods and telescopes (field of view, magnification) would have been different.

The search yielded 138 comments about non-stellar objects noticed. Of these, 56 objects are recorded in the NGC (in some cases, their discovery predates that of the NGC entry).

A further eight objects appeared in later works as independent discoveries: in the IC and in the catalogues by Trumpler and Collinder.

Of the remainder, 62 comments, referring to "scattered star fields", "groups of stars", or "clusters", were presented in Table 2 of Paper 1. In an expanded format, Table 1 below lists these objects along with the original comments, that caught my attention (column 6), as noted in the various catalogues. I also searched for mention of these objects in later catalogues (last column).

Table 1. Non-stellar objects noted in old astrometric catalogues.

The Deep Sky Hunters collaboration

In 2004, Philipp Harald Teutsch of the Deep Sky Hunters collaboration examined the list, suggesting cross-identifications and providing extensive commentary on the objects.

Combining Teutsch's comments with my own cross-identifications from Paper 1 results in a list of discovery observations that suggests alternative discovery credit for some objects (Table 2).

Key: Column 1: Suggested modern cross-identification. Col 2: Catalogue(s) noting the object. Col 3: Number in Table 1 where applicable. Col 4: Cross-id suggested by Teutsch (PHT) or Slotegraaf (AS).

Footnote 1: PHT has suggested that object 19, commented as "neb[ulous]" in the entry for Brisbane B1972, could be NGC 2566. I would tend to disagree, because I think it would have been too faint.
NGC 2566 is an 11th magnitude galaxy; William Herschel in 1785 (18.7-inch f/13 speculum telescope) called it "very faint", and Howe, using a 20-inch refractor, called it "either a very small nebula, or a nebulous 11th magnitude star with a 12th magnitude star close."
In the Preface to the Brisbane catalogue the "principal instruments" are described: "... a 5.5-feet transit instrument, by Troughton; a 2-feet mural circle, having a telescope of the same length, by the same artist; a 16-inch repeating circle, by Reichenbach; a 46-inch achromatic telescope, with equatorial motion and wire micrometer, by Banks; a clock by Hardy..". According to Andrew James' comprehensive "A History of Parramatta Observatory", the Troughton transit scope had a 3.75-inch aperture. The equatorial telescope had a 3.25-inch lens. I strongly suspect that NGC 2566 would not have been visible in either instrument, especially if, as I understand, quite high magnification was used to observe transits.

Footnote 2: Similarly, object 23, described as "faint nebula, several small stars", is perhaps unlikely to be NGC 3084 or NGC 3078, as PHT suggests. NGC 3084, seen by John Herschel at the Cape (18-inch f/13 speculum telescope) is called "very faint, small, round, attached to a star 13th mag, S.f.". NGC 3078 is, if anything, a more likely candidate: John Herschel called it "bright, round, first gradually then much brighter to the middle, 30 arcseconds." It was first seen in 1784 by the elder Herschel, who called it "faint, small, round, small bright point in the middle, cometic."
However, I could be entirely wrong. I have no records of observations of these objects viewed with small refractors, and have only seen them in mid-sized reflectors. Any Gentle Readers with some input?

Teutsch commented extensively on the remaining objects. They were assigned a designation in the DSH catalogue, from which this table is extracted. Those marked "AST" are regarded as likely asterisms; a "???" indicates no analysis of the grouping has been carried out. In addition, examining the Tycho-2 database, he has provided estimates of the diameters of the groupings, expressed in arcminutes. His review comments appear in the final column.

Conclusion

The search for new open clusters, and deep sky objects in general, continues amongst the dedicated members of the Deep Sky Hunters. Join their discussion group at Yahoo! to find out some of the amazing things they are uncovering.

I'd like to thank Philipp Teutsch for examining the potential objects I came across; his comments and analysis greatly informed my efforts to see if, just perhaps, those dedicated (and to risk a pun, focussed) astrometrists of a century and a half ago had netted a deep sky object or two.

nothing more to see. please move along.
