Binocular Viewers

Celestron Stereo Binocular Viewer

   The Stereo Binocular Viewer allows you to adapt two eyepieces to your telescope and view with both eyes simultaneously. In addition to eliminating eye fatigue associated with viewing through one eye for a prolonged period of time, this bino viewer also provides a three dimensional effect while observing many celestial objects. The Stereo Binocular Viewer will also improve contrast on deep sky objects as well as solar system objects. The Stereo Binocular Viewer is designed to work with Schmidt-Cassegrain telescopes (SCT) and many refracting telescopes. High quality FMC BAK-4 prisms to reduce light loss Quality control inspected for collimation and performance. The Stereo Binocular Viewer requires you to use two eyepieces of equal focal lengths and optical design.

Standard Denkmeier Binoviewer

   The highly rated Denkmeier Binoviewers deliver spectacular 3D looking views in almost any telescope. You don't realize how much strain you put on your brain squinting through one eye until you use a quality binoviewer. Enjoy the relaxation offered by viewing with both eyes. The high quality 26mm clear aperture prisms are MgF2 coated to increase contrast and prevent ghosting. The self-centering eyepiece holders make setup much easier than other models that use set screws. Available in 3 different versions depending on the type of telescope you own. Includes foam padded hard case. Interpupillary range fully adjustable from 49mm-75mm.

   Refractor Package: Denkmeier Binoviewer plus 1.25" OCS for refractors. The patented OCS (Optical Corrector System) allows the focal plane to be moved out to the Binoviewer eyepieces with little gain in magnification, allowing wide field low power views impossible with other binoviewers. The OCS can be configured to provide 1.25X or 3X magnification. Also includes a 2" adapter that allows use of the OCS in 2" diagonals. Includes foam padded hard case.

   Newtonian Package: Denkmeier Binoviewer plus 1.25" OCS for newtonians. The patented OCS (Optical Corrector System) allows the focal plane to be moved out to the Binoviewer eyepieces with little gain in magnification, allowing wide field low power views impossible with other binoviewers. The OCS can be configured to provide 1.2X or 2.5X magnification. Includes foam padded hard case.

   SCT Package: Denkmeier Binoviewer plus SCT Richfield "Star Sweeper". The amazing Star Sweeper allows an F/10 SCT to operate at F/5 for huge views that surpass any giant binocular in detail because you have full flexibility of eyepice pairs and of course, potential for very large aperture of 5"-16". Widefield eyepiece designs of 20mm or under work best. Plossls of 26mm or shorter work best. Apparent fields are preserved. For example, 19mm Panoptics operate at 38mm with a 70 degree field with the Star Sweeper! Includes foam padded hard case.

Standard Denkmeier Power x Switch Binoviewer

   These packages include a standard binoviewer (see above) and the Patent Pending single arm Power x Switch optical system that moves the focal plane through the binoviewer while keeping the magnification at the lowest possible power. By switching the power arm position, high power can also be achieved in seconds. The Power x Switch is available for Newtonian, SCT's and refractors.

Low Power	High Power

   The Power Shift Arm can be set to the in-position for low power wide field viewing or the out-position when high power views are desired. This is accomplished in seconds with minimal refocusing required.

   Also includes a pair of SCD (Self-Centering Diopters) holders. These holders feature the self-centering-locking method of retaining eyepieces, but also introduces a helical focusing system that allows each eyepiece to be individually focused by rotating the holder itself. An extremely fine accuracy of focus is now possible for each eye.
