I use this stable ball head with 10x50 binoculars, so it can handle it without any problems. Tension adjustment could be better, but overall I'm happy with it. I've also tried it with an 80mm doublet telescope and it handles it fine at low magnification. At high magnification (over 100x) the tracking is not smooth enough for me. Overall, it's a nice get-to-go. I would buy this again.
