Hale 7 w BINOCULAR REFLECTING TELESCOPE ABSTRACT OF THE DISCLOSURE A binocular reflecting telescope for astrono- mical or terrestrial use having two telescope tubes dis- posed side by side. Each tube has primary concave mirrors operating as Herschelian Newtonian to direct incident light as a reflected first pencil of light rays towards a plane secondary mirror disposed adjacent a portion of the side wall of the respective tube which is also adja- cent the remaining tube. Each secondary reflector re- flects rays as a respective second pencil outwardly of the tube into respective eye piece. The second pencils of light rays are reflected generally in the same direc- tion and the eye pieces are generally parallel and spaced apart at an appropriate interocular spacing to provide binocular viewing. Interocular axis extending between optical axes of eye pieces is disposed oblique- ly to parallel longitudinal axes of tubes to provide comfortable viewing. One tube is movable axially rela- tive to the remaining tube to swing interocular axis to vary interocular spacing.
