ABSTRACT:
An optical instrument has a low powered light point source mounted on a tube for orienting light point source along a predetermined viewing axis for one eye of an observer. An optical void surrounds the point light source, including the tube. The light point source is coherent and/or collimated so as to be substantially free of autokinesis effects. The tube is mounted on orientable support structure for the predetermined viewing axis for one eye of an observer whereby when said observer is viewing a scene through his other eye an optically fused image is presented to the observer with said predetermined viewing axis including the point in said scene wherein said point source appears.
