M29 - Open Cluster in Cygnus
The Messier Ten Minute Challenge
M29 - Open Cluster in Cygnus The open cluster M29 (NGC 6913) lies at a distance variously quoted at anything between 4000 and 7000 light years. It has a diameter of 11 light years and an estimated age of about 10 million years. The cluster would be three magnitudes brighter if it were not for interstellar dust. http://www.martin-nicholson.info/ten...llenge/m29.htm Martin Nicholson, Daventry, England.
