Not only is N6752 the third brightest globular, it is also one of the nearest! According to the Globular Cluster Catalog of W.E. Harris, it is at 4 kiloparsecs, in other words.....13,000 light years.
This relatively small (for a globular!) distance is one reason why this is one of the few globulars in which stars can easily be seen when visually observing with a 3 inch telescope.
But M22 is even nearer (3.2 kiloparsecs).....that's why it is so gigantic, in angular diameter.
cheers, mad galaxy man
