This image composition of the open cluster Messier 29 (M29 or NGC 6913) was taken on 17-18 November 2016. M29 is found near the star Sadr, the center star of the Northern Cross asterism (in the constellation Cygnus). It is a rich field of sky where the Northern Milky Way passes directly through. M29 has an apparent magnitude of 7.1 and is about 4,000 light years away. I think of M29 as a tiny version of the Pleiades cluster, even the form looks similar.

Tech Specs: The wide field image was done on November 18, 2016 using a Canon 6D, Canon EF70-200mm f/2.8L USM lens, mounted on an iOptron ZEQ25GT mount. 12 x 30 seconds, 5 x 30 second darks and 5 x 1/4000 second bias, ISO 3200, f/4, 200mm, unguided. The close up view was done on November 17, 2016 and is composed of 24 x 15 second images at ISO 3200 with 5 x 15 second darks and 5 x 1/4000 second bias frames using a Meade LX90 12” telescope and Canon 6D camera mounted on a Celestron CGEM-DX mount. Imaging was done from Weatherly, Pennsylvania.

I have as well, Starry Nights software lists it as that but I haven't seen a reference as to how the name was derived. Burnham doesn't mention the name in his references. Anyone else have any thoughts?

The first time I saw M29 was with my 6 inch reflector.  Two thoughts occurred to me: (1) Rather unimpressive for a Messier object. But it does have a subtle beauty to it. (2) It looked like the letter "H".
