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. 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
1. The 45 degree angle is very uncomfortable for high angle viewing .
2. Interocular adjustments require refocusing.
3. The 45 degree angle makes it difficult to use with reflectors.
4. 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 and, 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 Dobsonain, 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.
