Orion Premium Linear BinoViewer for Telescopes

Enjoy amazing 3D-like views through any telescope with Orion's newest and most advanced stereo binocular viewer! The Orion Premium Linear BinoViewer makes observing a wonderfully comfortable and immersive experience, because you're using both eyes instead of just one.

 

Unlike other binocular viewers on the market, Orion's innovative Premium Linear Binoviewer boasts a sliding "linear" housing for adjusting the interpupillary distance (IPD) instead of the traditional folding body. That matters because the folding types are more prone to collimation problems, whereby the two barrels of the binoviewer become misaligned, causing double images and eye strain. With this Linear BinoViewer you just slide the two halves of the housing inward or outward to set the IPD (from 58 mm to 74 mm) and there's a handy IPD scale laser engraved on the housing so you'll know exactly where to set it the next time for your (or anyone's) eyes.

 

The eyepiece holders of the Premium Linear Binoviewer accept any two identical 1.25-inch telescope eyepieces (sold separately), and have convenient twist-tight holding collars that are self-centering. No little thumbscrews to mess with and no chance of miscollimation due to eyepiece offset in the barrels. The right eye side is equipped with a helical diopter adjustment. The binoviewer's tapered 1.25-inch barrel minimizes the possibility of accidental fall-out, which is good because at 1.5-pounds this viewer adds a hefty load onto the diagonal or instrument itself. The barrel is threaded for use of Orion 1.25-inch filters.

Another big advantage of the Orion Premium Linear BinoViewer is that it does not utilize prisms in its optical design (just mirrors and lenses) thereby eliminating optical aberrations associated with prisms, while improving contrast. A knife-edge mirror is employed for light path splitting, rather than a prism used in traditional binoviewers. The dielectric-coated mirror, which boasts 99-percent reflectivity, minimizes differences in brightness, contrast, and color tone between the left and right images compared to prism-containing binoviewers. And four of the internal lenses are made from lanthanum glass, which effectively suppresses chromatic aberration.

 

Other big advantages of the Orion Premium Linear BinoViewer over most competing binoviewers include:

  • The Premium Linear BinoViewer can be used with any type of telescope, even reflectors.
  • It requires no additional backfocus or in-travel and does not alter the magnification of the optical system. You won't need a Barlow lens to reach focus as with some other binoviewers.
  • Its built-in image erecting system means you can use the Premium Linear BinoViewer without a diagonal, if desired, and get a "normal" upright image
  • Low-power viewing is both possible and pleasurable with the Premium Linear BinoViewer, which is not the case with many binoviewers, since you don't need a Barlow lens with ours to achieve focus.

 

 

To use the Orion Premium Linear BinoViewer with a diagonal, Orion recommends their Pentaprism 90-degree 1.25-inch Diagonal (#OR-52055), as it will provide a correctly oriented image. Use of a standard star diagonal or a "correct-image" diagonal will both yield an upside-down image.

 

The Premium Linear Binoviewer comes complete with a roomy, waterproof hard carrying case for protection and convenient transport of your device. There's enough room inside to allow storage of a pair of 1.25-inch eyepieces and the Pentaprism diagonal (all sold separately) in addition to the BinoViewer! Whether you're gazing during the daytime or under the stars at night, the versatile and revolutionary Orion Premium Linear BinoViewer will bring a whole new dimension of stereoscopic immersion and comfort to your observing sessions - no matter what type of telescope you are using.
