Yep, that pretty much sums it up! I've seen 105 MW globular clusters through my 4.5" reflector from my backyard, but only a small percentage would be resolvable in that aperture. Have to do a countback sometime. However there's probably a bit of an issue with what 'resolvable' means. I'm thinking that on a good dark night with excellent seeing (the latter rare around my neck of the woods!) you can start to perceive graininess in some of the dimmer clusters that normally appear diffuse but I don't imagine you'd class that as 'resolved'. Superior optics in a good refractor would no doubt help too.
