" Note: The catalog number "L I.5" designates: that the nebula is listed in Lacaille's catalog of 1755 (hence the "L"); that Omega Centauri is a nebula of the "first type" (première espèce, namely, nebulae that do not seem to be accompanied by stars when viewed via a telescope that is 2 feet long; hence the Roman numeral "I"); and that Omega Centauri is listed fifth among the nebulae of the first type (hence the "5").

Cheseaux compiled a list of nebulae during 1745–1746. He sent the list to his grandfather, in the form of a letter. The letter was read before the French Academy of Sciences in 1746. However, it was first published only in 1892 as part of a large article by the French astronomer Guillaume Bigourdan.

However, towards the end of the book there appears "Tabula quadragesima prima, Centaurus." (Forty-first table, Centaur). The table lists Omega Centauri as "21 ω In imo dorso" (21 ω At the bottom of the back). The following page shows the constellation Centaur and Omega Centauri as a star labelled ω at the base of the Centaur's back.
