Globular cluster by Kaus Borealis, found easily in the
same field of view with it at 40x. It was brighter
than I excpected, but small. At 100x it looked like
usual globular cluster, gradually brighter toward
center and fading out not slowly. At any magnification
I couldn't see any further details. Field of view 
is rich of stars. Sketch is available at the URL
