The first edition covered 45 objects numbered M1 to M45. The total list published by Messier finally contained 103 objects, but the list "got an independent life" by successive additions by other astronomers, motivating the additions by side notes in Messier’s and Mechain’s texts indicating that either of them knew of the objects. The first such addition came from Nicolas Camille Flammarion in 1921, who added [[Messier 104]] after finding Messier’s side note in his 1781 edition exemplar of the catalogue. M105 to M107 were added by Helen Sawyer Hogg in 1947, [[Messier 108]] and [[Messier 109]] by Owen Gingerich in 1960, and [[Messier 110]] by Kenneth Glyn Jones in 1967.<ref>[http://en.wikipedia.org/wiki/Messier_object Messier Object]</ref> | The first edition covered 45 objects numbered M1 to M45.

For our purposes working with deep sky objects that remain hidden in the current list of [[Messier Objects]] that are listed to 110, our HGS manual lists Messier 111-Messier 120 as potential hidden deep sky objects that are identified by Guardian Krystal Star forces when incorporating these objects into an HGS session. | For our purposes working with deep sky objects that remain hidden in the current list of [[Messier Objects]] that are listed to 110, our HGS manual lists Messier 111-Messier 120 as potential hidden deep sky objects that are identified by Guardian Krystal Star forces when incorporating these objects into an HGS session. | ||
