If globular cluster NGC 5897 (2022) ranks low on the Shapely-Sawyer concentration scale, Messier 75 comes out at the top of it's class with a rank of 1 (I). If it wasn't for being on the other side of the galactic center, it would be much more spectacular to image. The cluster has a radius of 67 light years, and contains some 400,000 stars. Would definitely be a sky full of bright stars if one was located inside the cluster.
