Abstract
A focusing arrangement for focusing reflecting telescopes comprises a lever gear means operated by an adjustment screw, which is provided between the rear interior face of a telescope housing and a telescope mount for displacing the latter and the reflecting telescope as required. In diametral opposition to a connection point between the telescope mount and the gear means relative to an optical axis a resilient means is provided for acting on and counteracting the adjustment operation exerted by the screw and lever combination in the course of which the telescope and mount are displaced along a guide means symmetrically provided about said optical axis.
