This mount seems to be able to cope with pretty much anything you can throw at it. It handles a heavy scope like the Sky-Watcher 180mm SKYMAX Mak Pro effortlessly, and even a very long scope like a Sky-Watcher 150PL is unrestricted in movement in all but the zenith (and you can just reposition the tripod legs when this becomes an issue). Movement is - on the whole - very smooth, but there is nonetheless some backlash inherent in the design thus making this mount perhaps not the best choice at high magnification. For low-to-medium power use however, this mount is a joy to use, feeling robust to an almost industrial degree, and is as much fun to use with a large telescope as it is with a small one. The supplied L-bracket - whilst not long enough to host binoculars - nonetheless rounds the package off nicely, enabling the use of most cameras, spotting scopes and video cameras with the mount. A good-quality product that's built to last.
