M69

M69 = NGC6637 ( 18h 31.4m -32°21´, 7.7 mag. )

This globular cluster in Sagittarius was discovered by Lacaille in 1752 and Messier observed it on August 31, 1780.

M69 (NGC 6637) is a globular cluster of little merit.
M70 (NGC 6637) is another globular cluster, two degrees east of M69. It too is of little interest.
M75 (NGC 6637) is the faintest of globular clusters in this constellation.

A close neighbor to M69 in Sagittarius is the globular cluster M70. This cluster is nearly identical to its neighbor in size and brightness, although it is just a bit larger.

M69 and M70 were added in a separate contribution to the end of the same volume. The final published version appeared again in Connaissance des Temps for 1784 (published in 1781) which contained objects through M103.

Más de una docena de objetos residen en Sagitario, incluyendo los racimos globulares M69, M70, y M54 que yacen a lo largo de la parte inferior de la tetera.

Subsequently, Abbé Lacaille would list NGC 104, NGC 4833, M55, M69, and NGC 6397 in his 1751-52 catalogue. The M before a number refers to the catalogue of Charles Messier, while NGC is from the New General Catalogue by John Dreyer.

At the very edge of Sagittarius, at the border to Ophiuchus and Scorpius lies the center of our galaxy.
