Abbe Lacaille's Original Catalog -

Abbe Nicholas Louis de la Caille’s Original Catalog

Lacaille’s catalog was one of the first more

systematic Deep Sky catalogs in the

history of the Discovery of the Deep Sky Objects.

Here we present a translation of the original Lacaille Catalog, as it was

reprinted in an appendix to Charles Messier’s Catalog

in 1781 in the Connaissance des Temps for 1784.

In this reprint, Messier represents the objects by their position

(Right Ascension and Declination) rather than their numbers in Lacaille’s

catalog.

Nebulae of the Southern Sky.

Observed by M. l’Abbe de la Caille, from the Cape of Good Hope.

The catalog printed in Mem. Acad. annee 1755, page 194.
