My 8" dob resolves the stars well in all but the very small ones with a 15 mm ortho. To me, they look like greenish blobs with the stars on the outer layers. On the biggest ones like M13, M22, and M92, I can pretty much resolve stars to almost the core.
I will be getting the Meade 16" starfinder dob someday soon. Going to be a pain to transport but with having a pickup it won't be that tough. I cannot imagine what my clusters will look like through this scope.

With my 22" Dob and my 5mm Nagler (501x). Globs like M-13, M-22, M-5 and so on, makes me feel I'm on the starship Enterprise with a voice saying " Captain Kirk we are now entering the globular cluster"!

Makes me look forward to getting the 16" Starfinder even more. I wish coulter still made their 17" dob, it was only $1000 and the optics were every bit as good as Meade or Orion.

Most globs look like misty spots in the ETX-125, but I have managed to resolve individual stars in six of them under best conditions from suburbia (ZLM 5.1 at best).
I have found that higher powers in the 120x-180x range give the best results.
M13 can be resolved well into the 'inner middle distance', with scores of stars visible in direct vision, and many more in averted, giving a hypnotic 'flickering fireflies' effect.
I have also resolved the outer parts of M3, M5, M15, M92, and - surprisingly from Northern England - M22 (at 12 deg up !).
Indeed, M22 was looser than M13 and gave up some of its stars at lower power.
No doubt Omega Centauri would blow even M13 and M22 out of the water.

I love the way globs look in both my bino's and 10". The wide field view is spectacular from from the perspective of context, whereas resolving deep brings its own reward. While so many were at the Mt Pinos party this week, we had a group at Blue Jay, and for the first time I was able to push my SCT up to insane powers! Viewing M2 and M92 at 832x was jaw-dropping. I have not begun to see them all as yet, but so far, M2 and M92 are my favorites because they sit in such isolation. Think I spent about 3 hours at the eyepeice with M2...and the time FLEW by!

They remind me of a gray-green popcorn ball made of stars.

G1 looks like a little faint fuzzy dot at 555x.

Last Friday night I was lucky to find myself in a "barrens area" (not a clear cut, rather a short stubby vegetation area, and sandy) in the middle of a local national forest. It was one of the most transparent nights i have seen in years, and the air was the unusual (for around here) combination of clear and dry.
I had my 80ED along. M13 in my 9mm orthoscopic was a shock. While not "resolved" across the main body, the main body of the cluster looked like a small, round pile of sugar, surrounded by a halo of scattered stars, with irregular tendrils resolved. I have never seen it that well in that small of an aperture.
A good sky really makes a difference.
Generally speaking, a 10" really kicks in on the globulars.

I have to agree with half meter, the image intensifying eyepeice is pretty amazing if you can afford one. I had a chance to look though his last weekend up in Gladwin Mi, it looks like the picture only better. Thanks for letting us look though it and showing us things we had never seen before. Jeff and I had a great time. Darris

No problem, Darris!
Glad you and Jeff enjoyed the I3 eyepiece. Some folks are initially turned off by the green color, but then most objections just melt away when they see a familiar globular

My 10" really resolves M13 and M3 very well.
My homemade 8" works well too.

The nights of August 6 and 7 were the best for some time, with ZLM of 5.2 / 5.3, and I could add three more globs to my 'part resolved' list :
Suspected in averted: M10
Seen in averted: M12, M2

I've been able to capture that granular appearance with a 6" reflector on M13, but can resolve it to the core with a 10" Dob, and you can really go deep with high magnification in an 18" Dob.
The 18" resolves a lot of the brighter globulars to the core, but I doubt even it can resolve the core in the really dim globs like NGC 6712. I haven't looked at 6712 in the 18", only in a 12.5", but it's awfully dim.
It's not considered a glob, but M11, the Wild Duck Cluster, looks entirely different in a big scope. In my 10", I can see a triangle shaped mass of bright stars like salt on black velvet. In my 18", it looks like a uniform nearly circular mass of salt on velvet, with a bright star near the center jumping out at you.

Maybe we should try tabulating "resolved" GC's vs. Aperture, but then we would need a definition of "resolved", wouldn't we?
