It is the 2nd closest globular to us (M4 being the closest), it has also undergone a core collapse and contains some of the hottest and most luminous stars of any globular cluster. Because of this and its close proximity, NGC 6397 contains the individual brightest stars of any globular cluster.

Hi John, NGC 6397 is my favourite GC next to 47Tuc & Omega Centauri!
I was going to include it in my list (Glen, I hope I'm not too late?) and then I saw your post- Wow!
I had no idea all this activity was on inside it.
Here are my obs notes on it:
"Very impressive!!! Large condensed core not resolved, but just outside the core are many loose, easy to resolve stars and outer stars are scattered as if GC has exploded. Bright."
MY LIST:
47Tuc (NGC 104)
NGC 5139 (Omega Centauri)
NGC 6397 (in Ara)
M4 (I love the bar structure & has a lot going on inside it)
NGC 6752 (in Pavo)
Why NGC 6752?
My obs notes:
"One of the prettiest GC's I've seen! Very bright, granulated bright core with bright stars sprayed out. Good size. Bright star to the right. Heavier concentration north of GC. South of GC are two trails of stars. Elongated south. 120x magnification used."
