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:
