OBJECT DESCRIPTION AND IMAGE SESSION
Another one of the originals discoveries of Charles Messier, M 29 was catalogued in July 29th of 1764. This object is the lower in declination I have ever imaged from Buenos Aires. Despite the mentioned, the cluster can be easily seen with binoculars within an impressive populated area of stars near gamma cygni. The linear diameter of the cluster is 11 light years, and its age is estimated in 10 million years. Its five hottest stars are all giants.
The cluster is very easy to find: just 1.7 degrees South and little East from Gamma Cygni (Sadr). From southerners observers the best time to see the object is by the end of the winter and the beginning of Spring.
