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.

Abstract: A binocular or other optical viewing instrument dedicated for eyeglass-wearing users. An extended optical eye relief, as compared to binoculars for those without glasses, provides an eyeglass-wearing user with an optimal wide field of view. A pair of soft rubber eyeglass guards cushion the binocular against the user's eyeglasses, both protecting the eyeglass lenses and blocking a substantial portion of the ambient light from striking the eyeglass lenses.

Abstract: Binoculars include a pair of housings pivotally hinged therebetween with each housing having an objective lens and an eyepiece lens for cooperating to magnify an image seen therethrough. Each objective lens and respective eyepiece lens are fixed in position relative to one another and are positioned at such a distance from one another such that the focus through the combined lenses is fixed at infinity.
