ABSTRACT:
An ocular turret telescope system for attachment to a conventional reflecting or refracting telescope or other optical instrument includes a plurality of integrated optical adjustment features. A rack and pinion slidable adjustment provides a viewer with a resolution adjustment. A rotatable filter and magnification selection turret enables the selection of one of several filters and/or magnification levels. A selectable eyepiece housing enables the selection of one of several eyepiece barrels of different aperture sizes which are sighted along the telescope barrel via an internal, reflecting mirror mounted at a 45 degree angle. Also, an end-mounted specialized eyepiece or camera mount automatically urges the internal, reflecting mirror upward and out of the optical viewing path of the specialized eyepiece or camera when the eyepiece or camera is connected to the ocular turret system.
