TeleVue
TeleVue Optics is a company with the mission to provide observation equipment of the greatest quality to astronomy enthusiast. The excellences in their products are due to the materials they use, their designs and their craftsmanship.
The founder Al Nagler was a professional optical designer and was involved in designing NASA lunar landing simulators, in 1958. His experience and passion for astronomy continues to be a major influence on TeleVue products.
TeleVue is known for their innovated designs on their eyepieces. Plössl series is TeleVue’s 50° apparent field eyepieces design. TeleVue Plössl series is recognized as the top of their class in performance and value. The Nagler series is the 82° apparent field eyepiece series that TeleVue offers. The Nagler comes in four models. TeleVue Nagler Type 4 models feature approximately 18mm of eye relief with the “instajust” eye guard for those who wear eyeglass. The Nagler Type 5 permits the largest true field possible with the focal lengths of 31, 26, 20, and 16mm. TeleVue Nagler Type 6 models is for the short focal length. And the Nagler Zooms are zoomable 50° constant apparent field eyepieces. The TeleVue’s Delos eyepieces are the 72° apparent field of view eyepieces. They are mid-to-short focal length line of 20mm eye-relief. The TeleVue Panoptic are the 68° apparent field eyepieces. They provide wide and bright views. Radan 60° Apparent Field eyepieces are great for eyeglass wears. This TeleVue Radan provide high image quality, ample eye relief, and are useful for a wide variety of telescopes and viewing situations. TeleVue ETHOS series is the 100° and 110° apparent field eyepieces. The field area of ETHOS is more than 50% larger than an 82° field eyepiece with high power and dark sky background.
Stargazers are thrilled with wide range of telescopes that TeleVue offers. The TeleVue 60 APO telescope/spotting scope is a 60mm, f/6, APO doublet refractor. It is super-compact, finder and day/night scope. Get the TeleVue 60is for great telephoto and imaging capability for digital cameras. The compact size TeleVue 76 is a 6mm, f/6.3, APO Doublet Refractor. It can be used for astronomical purposes, to spotting, to bird watching. TeleVue-85 is a 85mm, f/7, APO Doublet refractor. With APO performance and airline portability, the TeleVue-85 has been delighting astronomy and birding enthusiasts and reviewers alike. TeleVue-NP 101 is a 101mm f/5.4, APO (Nagler-Petzval) Refractor. It is a great portable refractor with a four-element objective lens system. The TeleVue NP 101is and NP 127is refractor telescope have exemplary wide field and planetary visual capability while adding features to make imaging easier and more flexible.
Design goals for TeleVue’s telescope mounts are portability and ease of use. They offer the Tel-pod mount, which is lightweight with smooth alt-azimuth motions. It is a great size for travelling. TeleVue Panoramic mount combines simplicity, portability, and computer capabilities. For heavier scopes the TeleVue Gibraltar is a perfect match. Their thick wood legs easily handle the loads. TeleVue Gibralter-5 is the Gibralter mount with a larger, heavier alt-az head, enabling it to hold a very heavy load.
TeleVue also produces a vast range of astronomy accessories and equipment. They offer adapters, barlows, correctors, diagonals, finders and so much more. From the simplest accessory to the most complex merchandise, Televue provides astronomy enthusiasts with products of the greatest quality.
Above all, we want your Tele Vue experience to be "...even better than you imagined."
Tele Vue Dioptrx — your prescription for better viewing! See the TECHNICAL NOTES.
In addition to matching all the key performance criteria of its 13mm sibling, the new 8mm version is parfocal in 1.25" focusers with Radians, Plössls, Type 6 Naglers and 1.25" Panoptics. Further, its lighter weight and smaller diameter than the 13mm Ethos makes the 8mm suitable for anyone using a binocular viewer.
|
In 1.25" mode, if you use Tele Vue's "high-hat" 2"-1.25" adapter, it will be parfocal with Tele Vue's Plössls, Radians, Type 6 Naglers, Nagler Zooms, 1.25" Panoptics and 8mm ETHOS.
|
The 10mm Ethos delivers: 100° apparent field (50% larger in area than 82° Naglers), comfortable eye-relief, (accepts DIOPTRX eyesight astigmatism correctors), distortion correction, high contrast and on-axis sharpness for planetary viewing.

Al Nagler eagerly pushed Ethos designer Paul Dellechiaie to extend the new 3.7mm focal length
to reach 110°, the same field as the LEM Simulator optics Al designed 45-years ago to train NASA
astronauts for lunar landings.
|
The new 4.7mm Ethos-SX, like its 3.7mm progenitor, is designed and crafted to combine its exceedingly wide field of view with all the contrast, color-rendition, distortion correction and center-to-edge sharpness needed to achieve that natural view.
|
We have not specifically endorsed the 13mm Ethos for Bino-Vue use because of the large diameter barrel. Even so, we were advised by Mike Harvey at the Winter Star Party (February 2008) that only 1-person in 25 had interpupilary limits with the bino'd Ethos (63.5-mm for the initial production 13mm).
|
The 17mm ETHOS is an ideal complement to the 31mm Nagler Type-5. They are parfocal (both have focus locations about 3/8" above shoulder) and the 31mm Nagler Type-5 has exactly twice the true field area.
|
Maximize your "spacewalk" experience with the 21mm Ethos. Transform your passage through the Milky Way with the 21mm’s nexus of contrast, power and field. Larger deep sky objects and rich star fields are its natural playground. Looking on-axis your field-of-vision is filled with 100º of stars, however wherever you chose to concentrate your attention you’ll see sharpness and richer contrast.
