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, 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
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.
- The 45° angle is very uncomfortable for high angle viewing.
- Interocular adjustments require refocusing.
- The 45° angle makes it difficult to use with reflectors.
- An erector must be added for terrestrial viewing.
We immediately recognized the advantages of a binocular attachment that
adjusts interpupillary 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.
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 the Tele Vue-76, Tele Vue-85 and Tele
Vue-NP101, 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
Plössls.
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 intensive operation is essential for a binocular viewer used at
planetary magnifications. Tele Vue has the facility and expertise to service the
Bino Vue should it be required. You always have that assurance with Tele Vue
