The Vixen Optics Berlebach Castor II Dual AZ Mount is a simple and versatile mounting solution for small telescopes, cameras, binoculars, and spotting scopes. Its unique design gives you an array of mounting options, from a single telescope with a counterweight on the opposite side to running two optical tubes in tandem to having a telescope on one side and a DSLR on the other performing wide-field photography.
These mounting options allow you to mount an optic on the primary dovetail clamp and, with optional accessories, use the opposite side for counterweight bars to balance the load, to install a second dovetail for a second telescope, or to use a quick release coupling for a camera, spotting scope, or binocular. With a single load on the primary dovetail, the mount has a payload capacity of 17.6 pounds and with loads on both sides the overall capacity increases to an impressive 26.5 pounds.
With its full 360° rotation capability on the latitude (horizontal) axis and its ability to tilt upward or downward more than 90° each way, the head is ideal for both astronomical and Earth-bound observations. For accurate movement with minimal vibration, each axis has a friction control knob that allows you to simply move the optic around by hand and have it stay where you release it without having to tighten knobs or lock clutches. The head has a standard 3/8"-16 threaded mount on the bottom for easy installation on a wide variety of photo/video/field tripods. This is just the mount head; a tripod is required for proper use.
