ABSTRACT:
A binocular telescope includes adjustable optical components. The telescope has at least two telescope halves, respectively having an optical axis passing through an ocular and an objective. The adjustable optical components lie between the ocular and objective in a respective housing tube. The telescope has, between the two telescope halves, an axis that is essentially aligned parallel to the two optical axes, and in which a shaft body is arranged. The shaft body has a longitudinal slot in which an adjusting body, displaceable in the longitudinal axis of the shaft body, is arranged. This adjusting body is adjustable in the longitudinal direction from outside the telescope, its axial movement being coupled with the movable optical components for common focusing. A separate drive knob is arranged to change the axial position of one optical component in one telescope half to compensate for visual defects.
