Abstract
A binocular telescope has a pair of eye-pieces set in threaded mounts and includes a mutual drive for the simultaneous focusing of both eye-pieces, whereby both eye-pieces are connected non-positively with each other via a frictional clutch which slides through when a predetermined limiting torsional movement is exceeded. The binocular telescope combines such advantages of a central drive as, for instance, convenient and accurate setting, along with the advantages of diopter setting, namely accuracy and easy readability.
