I am actually looking at this cluster right now from Chile using my 20" dob. My notes:

The cluster is at the zenith at the time of the observation. At 83x the edge is resolved and the core is compact. From there to 197x, 320x and 427x it gets resolved more and more with the core resolved at 427x. The cluster lies in a ring of stars with a string of stars running away from it pointing to a bright star. There are three spiral arm-like curls of stars that run out of the core. One of then ends in a string of stars perpendicular to the "arm". A very pretty cluster!
