Tele Vue Plossls, designed by Al Nagler, have been a recognized benchmark of performance and value in the class of 50 degree apparent field of view eyepieces. While the Plossls may be the least expensive eyepiece line, they still enjoy the same care and attention to detail as the most expensive. While it's easy for other manufacturers to vie for the lowest price, Tele Vue continues to believe that quality, performance and consistency will ultimately reward you with the most value for your dollar. \u003cbr\u003e\u003cbr\u003e Diffraction limited \"on-axis\" performance is a given. Using more expensive high-index glasses to reduce astigmatism and lateral color at the field's edge, Tele Vue Plossls deliver sharper images than any other brand of 4 or 5 element \"Plossl\" or Orthoscopic designs. The faster the focal ratio of your telescope, the greater your visual reward for using Tele Vue eyepieces. Tele Vue Plossls feature full multi-coatings for greatest light transmission and contrast. Blackened lens edges and internal anti-reflection threads tweak the last bit of contrast for maximum image detail. The sharper field focuses faint star light into perceptible points and allows those with un-driven mounts to gaze longer before re-positioning the image. \u003cbr\u003e\u003cbr\u003e The 55 mm focal length has the largest true field possible for 2\" eyepiece holders -3 times the true field area of any 1-1\/4\" eyepiece. The focal plane is placed at the end of the barrel to minimize vignetting. Performance with a Schmidt-Cassegrain telescope is remarkable since it avoids the image degradation and severe vignetting which occurs when using telecompressors. Long eye-relief and unique adjustable eyeguard for eyeglass wearers. \u003cbr\u003e\u003cbr\u003e In the 1-1\/4\" series Tele Vue included a long eye-relief 40 mm focal length in the series with a 43-degree apparent field. Like the 55 mm, its focal plane is at the barrel edge for maximum field in the 1-1\/4\" format. The 32 mm Plossl, with its larger 50-degree apparent field, will deliver the same true field as the 40 mm but with higher magnification. The 32 mm is parfocal with the shorter focal length Plossls. The 25 mm, 20 mm, 15 mm, 11 mm, and 8 mm Plossls round out the focal lengths for various observing from deep sky to planetary. They work best with Tele Vue Powermates to effectively double the number of focal lengths in your collection. Far superior to eyepieces usually provided as standard with most instruments. \u003cbr\u003e\u003cbr\u003e For a bit more than generic brands, you can own a genuine TeleVue Plossl!\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eOPT Product Number:\u003cspan style=\"color: #000000;\"\u003e\u003cb\u003e TE-EPL-55.0\u003c\/b\u003e \u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Tele Vue","offers":[{"title":"Default Title","offer_id":44858240138,"sku":"TE-EPL-55.0","price":256.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1594\/4815\/products\/5297db183d94ff00daa151a0f16e5a2c.jpg?v=1553305329"},{"product_id":"tele-vue-35mm-panoptic-eyepiece","title":"Tele Vue 35mm Panoptic Eyepiece - 2\"","description":"\u003cp\u003eThe Tele Vue 35 mm Panoptic Eyepiece\u003c\/p\u003e\n\u003cp\u003eWith the Panoptic series, Tele Vue has taken the Wide-Field concept to Nagler-like performance levels - A meaningful advance over any eyepiece in its 68 degree field class.

With a 13 mm focal length evoking the original 'Nagler' revolution, the field area of this new eyepiece is, at 100 degree, more than 50% larger than an 82 degree field. The Tele Vue 13 mm Ethos eyepiece is essentially multiple eyepieces, delivering the true field size of a longer focal length, narrower apparent field eyepiece with the benefits of higher power and darker sky background.\u003c\/p\u003e\n\u003cp\u003eTele Vue Optics is known for its in-house eyepiece and telescope designs by Al Nagler. Tele Vue's latest eyepiece brings new meaning to the term 'in-house.' The concept for the 13 mm Ethos 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.\u003c\/p\u003e\n\u003cp\u003eFollowing 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 guidance, Paul tweaked his design to fulfill the original goals. While sharpness is inherent to the optical design, contrast is maximized through the intelligent use of flat finished baffles and ultra low reflectance, high efficiency coatings tuned to the composition of each element.\u003c\/p\u003e\n\u003cp\u003eThe Tele Vue 13 mm Ethos eyepiece has now been shown at NEAF, TSP, RTMC, as well as other major astronomy events.

Wright H. Scidmore patented important ultra-wide angle eyepiece designs (one with long eye-relief) in the 1960s for the U.S. government. His influence can be seen in many eyepiece designs on the market today with eyepieces of 68 to 80-degrees apparent field and more. Carl Zeiss made eyepieces of 110 and 120-degrees apparent field for use in U-boat periscopes before World War II. These are but two notable designers who developed ultra-wide field eyepieces over the decades. \u003cbr\u003e\u003cbr\u003e Like all Explore Scientific eyepieces, the lens elements of the 100 degree eyepiece are meticulously cleaned and aligned before being installed in their precision machined lens barrels. \u003cbr\u003e\u003cbr\u003e Each lens and lens grouping have EMD (Enhanced Multi-layer Deposition) Coatings and are edge-blackened to eliminate light scatter and maintain image contrast. \u003cbr\u003e\u003cbr\u003e Contrast is further enhanced with baffles that mask and deflect unwanted stray light. \u003cbr\u003e\u003cbr\u003e These eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods. These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil. \u003cbr\u003e\u003cbr\u003e Each 100-degree Series Nitrogen-Purged Waterproof eyepiece is internally sealed and purged with inert, dry nitrogen gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus, and to maximize the life of the internal coatings. \u003cbr\u003e\u003cbr\u003e To make sure, every 100-degree eyepiece is tested by submerging them down to 1 meter of water for 30 minutes. \u003cbr\u003e\u003cbr\u003e Years later such eyepiece designs transformed the visual experience for amateur astronomers, as they started using military surplus cannon sight eyepieces on their backyard telescopes. Al Nagler with his company Tele Vue introduced his Nagler 82-Degree eyepieces (and later introduced the 100-degree Ethos eyepieces), and then other commercial telescope companies such as Meade Instruments, Pentax, Celestron, and others made ultra-wide field eyepieces specifically for use in amateur telescopes. Since extreme performance eyepieces are expensive to make, they come with a relatively high price tag over standard eyepieces. \u003cbr\u003e\u003cbr\u003e After announcing Explore Scientific's line of telescopes at the Astronomical League Conference in the summer of 2008, we decided to focus on extreme performance, ultra-wide angle eyepiece designs as well. We wanted to offer ultra-wide angle designs in popular formats at lower prices. Now more astronomers could experience the benefits of the amazing panoramic views these eyepieces provide. \u003cbr\u003e\u003cbr\u003e Each and every Explore Scientific eyepiece is inspected both at the factory and again at our USA facility in California. \u003cbr\u003e\u003cbr\u003e Here we are making final visual and cosmetic inspections where we check for assembly integrity, cleanliness, and optical performance (including a test for visual image edge consistency) before shipping them to our customers. \u003cbr\u003e\u003cbr\u003e Developing our new eyepieces we wanted to take a fresh perspective and address several points. Our goal was to produce an ultra-wide angle design that provides pride of ownership at a great value: \u003cbr\u003e\u003cbr\u003e\u003cbr\u003e \u003cb\u003eFocus on Value\u003c\/b\u003e - We invite direct comparison to any eyepieces on the market in their category. \u003cbr\u003e\u003cbr\u003e \u003cb\u003eProtection from the Outdoors\u003c\/b\u003e - By making the eyepiece body nitrogen-purged and waterproof eyepiece internal elements will remain as pristine as the day they were assembled. The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements.

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 100 degrees of stars, however wherever you chose to concentrate your attention you'll see sharpness and richer contrast.\u003c\/p\u003e\n\u003cp\u003eThe optical performance of the 21mm is the work of Ethos lead designer Paul Dellachaiae, 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.\u003c\/p\u003e\n\u003cp\u003eExtending 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. The 21mm focal length completes the logical set of 21mm\/ 13mm\/ 8mm and nicely juxtaposes the 17mm\/10mm\/6mm combination. Each step within these two sets approaches a 3X field area gain. The 21mm's effective field stop diameter is 36.2mm, bringing its true field close to the 35mm Panoptic (38.7mm Field Stop diameter). Its true field is also larger than the 26mm Nagler with its 35mm effective field stop diameter. In an f\/4 Dobsonian, the exit pupil is just 5.25mm using the 21mm Ethos instead of 8.75mm with a 35mm Panoptic, or 6.5mm with a 26mm Nagler.\u003c\/p\u003e\n\u003cp\u003eLike all Tele Vue eyepieces, every 21mm Ethos goes through our optical and cosmetic quality control procedure in Chester, NY and should your eyepiece ever need service we can do everything from replacing a dented barrel to replacing a scratched eyelens.\u003c\/p\u003e\n\u003cp style=\"text-align: left;\"\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cstrong\u003eTele Vue 21 mm Ethos Specifications...\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFocal Length: 21 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eApparent Field: 100 degree\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eEye Relief: 15 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eEffective Field Stop Dia.: 36.2 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eBarrel Size: 2\"\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli\u003eWeight: 2.25 lb\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003eOPT Product Number: \u003cspan style=\"color: #000000;\"\u003e\u003cstrong\u003eTE-ETH-21.0\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Tele Vue","offers":[{"title":"Default Title","offer_id":44881335562,"sku":"TE-ETH-21.0","price":894.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1594\/4815\/products\/960d26206f276062fd44e662a438c5e5.jpg?v=1553301935"},{"product_id":"orion-26mm-q70-super-wide-angle-eyepiece","title":"Orion 26mm Q70 Super Wide Angle Eyepiece - 2\"","description":"\u003ccenter\u003e\n\u003ch2\u003eOrion 26mm Q70 Super Wide Angle Eyepiece\u003c\/h2\u003e\n\u003c\/center\u003e\nPeering into space with a 26mm Orion Q70 2\" Super Wide Angle Eyepiece puts your favorite nebulas and galaxies in a wonderful new perspective.

Wright H. Scidmore patented important ultra-wide angle eyepiece designs (one with long eye-relief) in the 6s for the U.S. government. His influence can be seen in many eyepiece designs on the market today with eyepieces of 68 to 8 degrees apparent field and more. Carl Zeiss made eyepieces of 11 and 12 degrees apparent field for use in U-boat periscopes before World War II. These are but two notable designers who developed ultra-wide field eyepieces over the decades. \u003cbr\u003e\u003cbr\u003eLike all Explore Scientific eyepieces, the lens elements of the 1 eyepiece are meticulously cleaned and aligned before being installed in their precision machined lens barrels. \u003cbr\u003e\u003cbr\u003eEach lens and lens grouping have EMD (Enhanced Multilayer Deposition) Coatings and are edge-blackened to eliminate light scatter and maintain image contrast.\u003cbr\u003e\u003cbr\u003eContrast is further enhanced with baffles that mask and deflect unwanted stray light.\u003cbr\u003e\u003cbr\u003eThese eyepieces with their huge apparent field of view not only gave the observer a panoramic visual experience, but they relax the eye so the observer could pay attention to subtle details for extended periods. These ultra-wide angle eyepieces played a critical role in the military for aiming at targets, and their long eye-relief counterparts helped reduce eye injury from recoil. \u003cbr\u003e\u003cbr\u003eEach 1 Series Nitrogen-Purged Waterproof eyepiece is internally sealed and purged with inert, dry nitrogen gas to prevent internal fogging, to halt the intrusion of fine particulates and fungus, and to maximize the life of the internal coatings.\u003cbr\u003e\u003cbr\u003eTo make sure, every 1 eyepiece is tested by submerging them down to 1 meter of water for 3 minutes. \u003cbr\u003e\u003cbr\u003eYears later such eyepiece designs transformed the visual experience for amateur astronomers, as they started using military surplus cannon sight eyepieces on their backyard telescopes. Al Nagler with his company Tele Vue introduced his Nagler 82 Degree eyepieces (and later introduced the 1 degree Ethos eyepieces), and then other commercial telescope companies such as Meade Instruments, Pentax, Celestron, and others made ultra-wide field eyepieces specifically for use in amateur telescopes. Since extreme performance eyepieces are expensive to make, they come with a relatively high price tag over standard eyepieces.\u003cbr\u003e\u003cbr\u003e After announcing Explore Scientifics line of telescopes at the Astronomical League Conference in the summer of 28, we decided to focus on extreme performance, ultra-wide angle eyepiece designs as well. We wanted to offer ultra-wide angle designs in popular formats at lower prices.

The sealed, dry environment is impervious to internal fogging and contaminants such as fungus growing in between the lens elements. Our waterproof eyepiece is easier to clean, and there is no risk of cleaning solution migrating from the top of the lens and seeping around edges to be trapped in between elements. To insure a perfect seal we test every eyepiece in one meter of water for 3 minutes. \u003cbr\u003e\u003cbr\u003e\u003cb\u003eCreating an Identity\u003c\/b\u003e - We look at purchasing fine optical equipment as an investment, and it should be treated as such.

In summary, it is a high contrast and respectably high field of view eyepiece at an amazing price.\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"color: #000000;\"\u003e\u003cstrong\u003eSpecial Features: \u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eWaterproof\u003c\/li\u003e\n\u003cli\u003eAverted Viewing Optimized\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eUNLIMITED LIFETIME, TRANSFERABLE WARRANTY!!\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e OPT Product Number: \u003cspan style=\"color: #000000;\"\u003e\u003cstrong\u003eES-EPWP6232LE-1\u003c\/strong\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c!-- split --\u003e\n\u003cul\u003e\n\u003cli\u003eFocal Length: 32 mm\u003c\/li\u003e\n\u003cli\u003eBarrel Size: 2\"es\u003c\/li\u003e\n\u003cli\u003eField of View: 62 degree\u003c\/li\u003e\n\u003cli\u003eEye Relief: 22.2 mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Explore Scientific","offers":[{"title":"Default Title","offer_id":218902822922,"sku":"ES-EPWP6232LE-1","price":229.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1594\/4815\/products\/explore-scientific-62-32mm-eyepiece-2-1.jpg?v=1553279880"},{"product_id":"baader-hyperion-8-24mm-clickstop-zoom-eyepiece-mkiv-with-hyperion-zoom-barlow-2-25x","title":"Baader Hyperion 8-24mm Clickstop Zoom Eyepiece MkIV with Hyperion Zoom Barlow 2.25x","description":"\u003cp\u003eA bundle of Hyperion 8-24 mm Clickstop Zoom Eyepiece Mark IV with a Hyperion Zoom 2.25x Barlow Lens\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConsists of Hyperion Universal Zoom Mark IV, 8-24mm eyepiece and Hyperion Barlow lens 2.25x\u003c\/li\u003e\n\u003cli\u003eThis combination of Hyperion Zoom and Hyperion Barlow creates an all-in-one astro quality grade zoom providing a focal length range (with and without Barlow) from 3.6 to 24mm\u003c\/li\u003e\n\u003cli\u003eIncludes all accessories that is delivered in the standard outfit of the Hyperion Zoom and Barlow\u003c\/li\u003e\n\u003cli\u003eATTENTION: Please note that this set of Zoom+Barlow is only meant for astronomical use.
