Ferenc --
Excellent sketches (as always)!
Indeed, I managed to resolve a few stars in 6535 under very good seeing:
Quote:
NGC6535 8/16/2007 00:00 UTC; Pickering 8, NELM 6, SQM 20.7
16" SCT
Odd bugger. 3 or 4 stars in direct vision at 260X, 10 - 12 in averted with more magnification (375X). Hints of variegation in core, but perhaps it's only a visual artifact from the resolved stars. Still pretty dim, but unlike any other GC I've viewed.
The observation is from before I started sketching, though, so no visual record.
I didn't even have the other two on my target list, but they are now. 
Cheers,
-- Jeff.

Thank you all for the kind words!
Jeff, nice to know, that I was right about 6535. Unfortunately my largest mag. is 250x now (even that is pretty uncomfortable to use with a dob), and no chance for a seeing of 8 here  Anyhow, I keep on observing this globular, because it has some potential in it.

With the sort of skies I have here, NGC-6535 is a very difficult object and thus far eluded my 10-inch. I've also tried for IC-1276 without success as of yet NGC-6517 and NGC-6539 on the other hand have revealed themselves as faint, comet like blobs of unresolved light, with a brighter core. As of late I have observed a number of other faint globular clusters in Ophiuchus, including NGC 6325, 6235, 6355, 6401 and 6426. All were very faint and difficult to make out in the hazy and light polluted skies.
