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. The optical performance of the 21mm is the work of Ethos lead designer Paul Dellechiaie, who achieved a level of optical aberration correction right in line with his other Ethos designs. Contrast and transmission have been maximized using the same advanced coating techniques and further aided by the internal mechanical design techniques used in all Tele Vue eyepieces. Extending the Ethos focal length... Less

Larger deep sky objects and rich star fields are its natural playground. Looking on-axis your field-of-vision is filled with 100 degree of stars, however wherever you chose to concentrate your attention you'll see sharpness and richer contrast. Extending the Ethos focal length range to 21mm while maintaining the original performance goals of the rest of the series brings the eyepiece up against the mechanical limits of the 2" barrel and focus constraints. The 21mm provides the maximum true field of view, has no significant vignetting at the edge of the field, and is parfocal with the 31mm Nagler Type 5. Like all Tele Vue eyepieces,... Less

Al Nagler eagerly pushed Ethos designer Paul Dellechiaie to extend the new 3.7mm focal length to reach 110-degrees, the same field as the LEM Simulator optics Al designed 45-years ago to train NASA astronauts for lunar landings (See reverse side for material on the LEM Simulator). Years after the LEM program, the memory of the 110-degree view of the simulated lunar surface moving through the triangular cabin window of the LEM inspired Al to develop an Ultra Wide Angle (his patent title) telescope eyepiece to approach that "simulator experience." When the 82-degree Nagler eyepiece hit the observing fields, it changed how amateur astronomers viewed the heavens. An early customer dubbed it a "spacewalk" view. Essentially, "the experience" is about creating an image as natural as one sees... Less

Al Nagler eagerly pushed Ethos designer Paul Dellechiaie to extend the 3.7mm focal length to reach 110°, the same field size as the LEM Simulator optics Al designed years ago to train NASA astronauts for lunar landings. The 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. Compared to a lower power eyepiece with the equivalent TFOV (similar field stop)such as an 11mm Pl"ssl (9.1mm field stop), the greater power - for higher resolution, and smaller exit pupil (for a darker background to enhance contrast) reveals a deep sky experience "even better than you imagined". The 4.7mm is a 1¼" format and is... Less

Tele Vue's soft, TV-76-sized Ethos eyepiece bags dense foam protects eyepieces from shock and holds the case rigid. it will not flex even when loaded. The bag is an attractive medium gray nylon material, with foam inner liner. The exterior bag dimensions are 21" L x 9" W x 6" D. Carry handle and adjustable shoulder strap are included.

It's been quite a challenge to develop new Ethos eyepieces to the same performance standards achieved by the 13mm and 8mm models, perhaps the most honored in history. We hope the increased field of the 17mm and increased power of the 6mm will open up new visual experiences that Galileo could hardly have imagined, from small refractors to the largest Dobsonians.

With 110 deg., the Ethos-SX has 21% more AFOV area than the 100 deg. Ethos design. This permits 62% power increase from a 6mm Ethos, while retaining 68% of its TFOV. The 3.7mm actually has more TFOV than Tele Vue's 8mm Plossl, 6mm Radian and 5mm Nagler Type-6! In 1-1/4" mode, it is parfocal with the wide range of 1-1/4" Tele Vue Plossls, Panoptics, Radians, Naglers, Nagler Zooms and 6mm and 8mm Ethos eyepieces. The screw-on 2" adapter (included) is designed to make it parfocal with 13mm and 10mm Ethos when they are used in their 2" modes.

The 10mm Ethos telescope eyepiece delivers: 100-deg apparent field (50% larger in area than 82-deg Naglers), comfortable 15mm eye relief (accepts DIOPTRIX eyesight astigmatism correctors), distortion correction, high contrast and on-axis sharpness for planetary viewing. It is the do-it-all eyepiece perfect for all scopes that can utilize this focal length. And, "filling the hole" between the 13mm and 8mm makes it the ideal centerpiece for a 17mm/10mm/6mm Ethos set. An important benefit of the combination of large apparent field of view and shorter focal length is that for a given field in the sky, higher magnification results in a darker sky background. Fainter stars become visible and more detail is seen on all deep sky objects. Ethos provides another big magnification/con trast jump,... Less

Celebrate the start of the International year of Astronomy 2009, the 400th anniversary of Galileo's first use of an astronomical telescope, by showing friends and neighbors the best of our wonderful universe. The TeleVue philosophy (Ethos, if you will) has always been about inspiring spacewalk vistas by creating the finest "rich field" refractors and wide angle eyepieces. We hope the introduction of these new Ethos models will further rekindle the appreciation of astronomy and supoport all the worthy goals of IYA 2009.

A 100° apparent field of view is a truly astounding number by any astronomical standard. Given that your 'mind's eye' can concentrate upon approximately 50° of a viewing field at once, doubling that amount results in a view that you could feel like you're "just falling into". For any given magnification, an Ethos will show a whopping 50% more sky than the previous widest oculars. Sharpness is inherent to the Ethos' optical design, and contrast is maximized through intelligent use of flat baffle finishes and ultra low reflectivity, high-efficiency coatings tuned to the composition of each element. The Ethos does the job of many eyepieces, delivering the true field sizes of longer focal length, narrower apparent field eyepieces with the benefits of higher power and darker sky backgrounds. ...

Televue Ethos Eyepiece Carry Bag ETB-0020

Tele Vue is known for its in-house eyepiece and telescope designs by Al Nagler; our latest eyepiece brings new meaning to the term "in-house." The concept for this eyepiece was first proposed by Tele Vue President David Nagler, with performance parameters giving it the fundamental characteristics (the ethos) of a Tele Vue eyepiece: high contrast, comfortable eye relief and full field sharpness. Control of astigmatism, field curvature, lateral color, angular magnification distortion correction (technical reference), and low pupil sensitivity for daytime use were specified criteria. Following Tele Vue's philosophy of pushing the state of the art, long-time Tele Vue employee and optical design protege Paul Dellechiaie took up the challenge and designed the basic eyepiece form. Under Al's... Less

Introducing the Televue 6mm Delos Eyepiece. The latest from Televue the 6mm Delos Eyepiece was a hit at NEAF 2011. According to David Nagler of Televue the Delos project started in 2008. The goal was to build an eyepiece that retained many of the same optical features as the the wildly successful 100 degree Televue Ethos eyepiece line within a 72 degree field.By reducing the field to 72 degrees it allowed the engineers over at Televue to offer more eye relief, 20mm to be exact. Every optical, mechanical and ergonomic aspect of this eyepiece was carefully thought out in order to maintain the classic Televue excellence we have come to rely on.New to the Televue Delos is the adjustable eye guard that locks into position. This enhances contrast by preventing stray light from entering the... Less
