ABSTRACT:
A binocular telescope comprises right and left slide plates, and right and left mount plates disposed on the right and left slide plates. Right and left telescopic optical systems are mounted on the right and left slide plates which can be moved to adjust interpupillary distance for a user. A part of the right telescopic optical system is mounted on the right mount plate, and a part of the left telescopic optical system is mounted on the left mount plate. The right and left mount plates are moved along the optical axes of the right and left telescopic optical systems, to perform a focusing operation. The right and left slide plates have straight portions extending parallel to the optical axes. The right and left mount plates have right and left guide shoes slidably engaged with the straight portions.
