An image of Messier 71, a small and loosely packed globular, has been uploaded

Hi all,

An image of the globular cluster Messier 71 has been uploaded. This cluster has been discussed as open or globular since it was classified as a cluster. After several switches, finally in the 1970’s it was classified as globular based upon photometry and the presence of a horizontal branch in the H-R diagram, typical of globulars. The image as well as some more info can be found at:

Messier 71. NGC 6838

Enjoy,
Josep
