I like how you mixed up one challenging object (Palomar 11) with 3 eye candy objects. That's usually how I observe also, though the proportions are usually reserved.
If you try Palomar 11 again on a night of good seeing and pump up the magnification, you should be able to resolve some of the cluster's stars, which appear starting at mag 15.5 or so.
Here's one of my observations from back in 2004 (with my 18")
At 225x, appears faint, round, ~3'-3.5' diameter with almost no central brightening although the globular fades around the periphery. Several faint stars are superimposed. It was difficult to estimate the size as the halo is not well defined. At times I felt the diameter was as large as 6' but sometimes only appeared 3' at best. At 435x, a half dozen faint stars are superimposed. The cluster's surface brightness is quite low at the magnification, though.
