M19 - Globular Cluster in Ophiuchus
The Messier Ten Minute Challenge
M19 - Globular Cluster in Ophiuchus Discovered in 1764. M19 (NGC 6273) is the most oblate known globular cluster. This may be due with its proximity to the Galactic Center: At 28000 light years away its diameter of 17 arc minutes equates to a diameter of 40 light years. http://www.martin-nicholson.info/ten...llenge/m19.htm Martin Nicholson, Daventry, England.
