I have seen this globular in a 4" refractor from very dark skies, and just barely with my 8" f/5 Newtonian from my light-polluted backyard. With no telescope have I resolved any stars in it visually. But here, with the camera, I can resolve many individual stars. This image is just 10x240" through an Astronomik CLS filter and SXVF-H9 camera through the CFF 290 Classical Cassegrain.
I made three mistakes in the version published earlier this month: 1) collimation was slightly off and 2) part of my guide camera was loose. These resulted in some slightly non-round stars I fixed as well as I could. This image suffered from none of these. However, this later image was taken on a night when the seeing was not quite as good. Still, it's a lot of fun to see this object at this magnification.
