A Newtonian binocular telescope (20), which is readily adaptable to popular telescope mounts, such as the Dobsonian mount (76), and which includes two primary mirrors (42a, 42b), and two secondary mirrors (32a, 32b), in a single tube (21) of either solid wall or open frame construction. The single tube (21) allows central secondary optical axes (34a, 34b) to be disposed in laterally and longitudinally separate parallel relation to one another so as to form a comfortable interocular axis (36) between them. Both telescopes' oculars (50a, 50b) are conveniently disposed adjacent an ocular wall (22) on a side of tube (21) nearest one of the telescopes. The viewer is provided easy access (91a, 91b and 92a, 92b) to primary alignment means (87a, 87b), which may be used to merge images between telescopes. Viewer is also provided a convenient means of moving one of the telescopes for interocular adjustment (70, 72), thus permitting the instant invention to be easily and quickly adaptable to multiple users, even as a large reflecting binocular telescope.
