M 29     (NGC 6913) 

M 29 is a small, compact open cluster located 1.75 degrees south of the bright star γ Cygni (Sadr) in the constellation Cygnus. It lies in a very rich portion of the Milky Way stream, surrounded by numerous other clusters and emission nebulas. M 29 would be a more spectacular object were it not reduced by 3.5 magnitudes due to the dense interstellar dust in this region. Without this extinction, M 29 would stand out as a magnitude 3 open cluster. M 29 lies at a distance of 3740 LY and has a physical diameter of around 10 LY. Its 7 brightest stars form a miniature Pleiades. The cluster contains around 230 member stars, many lost against the background of Milky Way stars.
M 29 was discovered by Charles Messier in July of 1764. He described it as a group of "seven or eight" stars surrounded by a nebula. The "nebula" was probably just the result of the poor optics of Messier's telescope.
