Bino Vue

For startingly "real" viewing, especially lunar and planetary.

Concept: At Tele Vue, the driving force has been to get as close to the contrast, resolution and field of the most remarkable instrument of all: the human eye. While always respecting the need for viewing comfort, convenience and value, we have broken through conventional barriers to bring you eyepieces and telescopes with performance dramatically closer to our "spacewalk viewing" goal. A major limitation has been the lack of binocular viewing. Looking at the night sky with one eye closed is missing a lot. Open both eyes and see the dramatic improvement in resolution, contrast, faint star detection and viewing comfort. All this plus an illusion of depth. Yes, your brain loves two eyed viewing, even when it's not true stereo. Open your eyes and mind to Bino Vue. -Al Nagler

Limitations of ordinary binoculars

You're probably aware that the color correction and resolution of all high powered binoculars is far less than ideal. Usually the size, weight, cost, inconvenience and lack of interchangeable eyepieces render them undesirable for all but the most die hard fans.

Limitations of ordinary 45 degree binocular attachments

  • The 45 degree angle is very uncomfortable for high angle viewing .
  • Interocular adjustments require refocusing.
  • The 45 degree angle makes it difficult to use with reflectors.
  • An erector must be added for terrestrial viewing.
  • Enter Bino Vue

    We immediately recognized the advantages of a binocular attachment that adjusts interpupulary distance like an ordinary binocular and sets up as easily as changing an eyepiece. The in-line viewing arrangement allows inter-ocular adjustment without focus shift. And, we use the largest prism apertures possible.

    The Tele Vue Touch

    To permit Bino Vue to reach focus with any telescope, we engineered an optical elimination of its 5.1" path length. Our special compensator lens system makes the Bino Vue parfocal when fully inserted to its stop end, results in only a 2x increase in magnification. The compensator lens also corrects for prism effects that can degrade high power viewing.

    For short focal length scopes such as Tele Vue's Pronto, Tele Vue-85 and Tele Vue-101, the 2x amplification results in low powers down in the 30x range. Even larger instruments will find the Bino Vue extremely versatile. For example, a 13.5" f/4.5 Dobsonian, would have a low power limit of 96x with a pair of 32mm Plossls.

    SCTs have enough focus travel to use Bino Vue without the compensator. For any scope that can accept Bino Vue's 5.1" of path length, we also include an empty tube to install in place of the amplifier assembly.

    Finally, Tele Vue tests the collimation and image quality of each unit. This time and labor intesive operation is essential for a binocular viewer used at planetary magnifications. Collimation is critical and delicate. Tele Vue has the facility and expertise to service the bino Vue should it be required. You always have that assurance with Tele Vue.

    A Final Note

    If you use Bino Vue with any of our telescopes for terrestrial viewing, you will enter a new world of visual experience. And, whether you're viewing in daylight or at night, you will hardly realize that each eye is seeing less than 50% transmission normally seen at the same magnification. The reason is that the resolution and contrast are so high and two eye viewing seems to "recover" some of the light loss. Indeed until you go to very high powers, you may prefer these views with seemingly darker sky backgrounds.
