Abstract
A wide field monocular is provided which is essentially a wide field virtual telescope. Two of these monoculars can be placed side-by-side to achieve a binocular with an extended monocular field. Also for such binoculars with objective lenses larger than the interocular separation, lunes can be cut from the objective lenses so that they can be placed adjacent each other, with the eyes essentially aligned with the optic axis of each telescope. This provides a remarkable wide field binocular with stereo vision and depth perception.
