Many Cassini binoculars are tripod adaptable via a binocular tripod socket located near the center focus of the binocular. A tripod adapter is required to properly adapt the binocular to the tripod. With the Cassini Universal Tripod Adapter you can properly adapt any binocular with a tripod socket and 1 inch (25.4mm) of clearance between the objective legs, to any camera tripod for hands free stable viewing.
