Bode's "Complete Catalog of hitherto observed Nebulous Stars and Star Clusters"

Johann Elert Bode (1747-1826), astronomer in Berlin and discoverer of M81, M82, M53 and M92, compiled a deepsky catalog of 75 entries published 1777 in the Astronomisches Jahrbuch for 1779, entitled "A Complete Catalog of hitherto observed Nebulous Stars and Star Clusters" (Bode 1777). This catalog was extended by 2 objects found by Bode (M92 and M64) and published in 1779 (Bode 1779).

Unfortunately, Bode's catalog contains many non-existent objects and uninteresting asterisms, mostly copied from elsewhere; personally he only claims to have observed and determined the positions of only 21 of the 75 objects before publishing his catalog. Possibly, he has observed at least one more object, Bode 1, which is perhaps the original discovery of IC 1434. It appears that Bode just copied together all the catalogs he had available (a method which was later repeated, on a larger number of objects and with more success, by John Herschel when composing the GC, and by J.L.E. Dreyer with his NGC and IC catalogs). Bode's list includes:

Bode missed M3 and included only a wrong positions for M28 as well as minor bugs for M53, M69 and M8 [Messier's position] because of data transcription errors (Bode 1781).

Because of this compilation method and sources, he has only 10 of the more conspicuous Messier objects beyond 45 included (mostly from Lacaille), and only three or four real deepsky objects which are not listed in Messier's catalog: Besides his possible original discovery of IC 1434, these are all from Lacaille, namely NGC 2477 = Lacaille I.3, NGC 2546 = Lacaille II.4, and perhaps Collinder 140 = Lacaille II.2 (depending on if this new identification is correct). 21 (or 22, if M40 is included) of the 77 entries do not match any deepsky objects and are either asterisms or simply errata, mostly copied without verification from other sources such as Hevelius.

After publishing his list and supplement, Bode continued to catalog deepsky objects. A notable publication of such a list, of 110 entries, occurred in 1782 in his atlas, "Vorstellung der Gestirne." Again, this list contains all the errata and astrisms mostly inherited from earlier lists, but also some more independent rediscoveries by Bode: An independent rediscovery of M48, for which Bode gives his own correct position, labelled "Monoceros 38" (in addition to listing also Messier's erroneous one), and one of IC 4665 which he cataloged as "Ophiuchus 125."

    Exclamation marks mark Bode's original discoveries, in parentheses an independent rediscovery (M50, M51, and M64, and later M48 and IC 4665), in square brackets presumably independent findings of published (in Messier's first catalog) known objects (M2, M10, M12, M15, M29, M33, M34, M37, M39, and M43); question marks indicate doubty identifications and minus signs nonexisting objects (e.g., asterisms, stars taken for nebulae, and errors).

    The author thanks Leos Ondra for providing him with a copy of Bode's original catalog which made this work possible.
