Introduced at the 2007 Northeast Astronomy Forum, Tele Vue once again broadened the amateur astronomer's perspective on the universe with: 100° of pure Tele Vue quality. The field area of this new eyepiece is more than 50% larger than an 82° field. The Tele Vue Ethos 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.
We invited NEAF attendees to take a look and see the universe the way we think it was meant to be experienced, with a field of view incredibly wide and sharp! We were very pleased indeed by the response and validation of our design goals.

The 3.5mm Nagler Type 6 is a natural progression of 1.4x power steps from 7mm and 5mm Naglers. You don't have to sacrifice field in order to gain sharpness and power. And, you're not limited to slow scopes, or have to squint through tiny eye lenses. These are the lunar and "planetary" eyepieces with field to spare.
Nagler Type 6
The 7-element, Nagler Type 6 design is based on the original patented Nagler design. This new 7-element design update for the short focal length Nagler deserves its own designation. Using different exotic materials, coating processes and design ingenuity, Al has massaged more eye-relief, contrast, and true field of view into the shorter focal length Naglers, while maintaining the absolute sharpness of the originals. Eye-relief is 12mm on each model, and all are sized about the same as the original 7mm! Weight about 0.4 to 0.5 lbs.
Concept: The goal we set designing these new eyepieces was to increase contrast, maintain or increase eye-relief, reduce size and weight, and maintain the sharpness of the originals. They are all parfocal and great with the Bino Vue.
Why Are There 4 Types of Naglers?
To achieve various features requires different design tradeoffs and thus the different types of Nagler eyepieces. The largest possible true fields of view for an 82°' apparent field of view in both 2" and 1¼" formats are achieved with the Nagler Type 5 series, with focal lengths of 31 and 16 mm
Compact size in medium to short focal lengths is achieved with the Nagler Type 6, available in focal lengths of 13, 11, 9, 7, 5, and 3.5 mm.
To achieve eyeglass friendly eye relief without excessively large and heavy designs requires the other two Nagler types. The 22mm Type 4 and 19, 14, 9, 5.5 mm Type 7 with their long eye relief feature adjustable height eyeguards and are best for eyeglass wearers or Dioptrx™ users.

The Tele Vue Ethos 8mm was first demonstrated at NEAF in 2008. In addition to matching all the key performance criteria of its 13mm sibling, the new 8mm version is parfocal in 1¼" focusers with Radians, Plössls, Type 6 Naglers and 1¼" Panoptics.
Its lighter weight and smaller diameter than the 13mm Ethos makes the 8mm suitable for anyone using a binocular viewer. A perfect eyepiece for terrestrial viewing with a short refractor. Comparing an 8mm Ethos to an 8–24mm Zoom eyepiece, the 8mm Ethos has the power of the 8mm Zoom and 83% of the field of the 24mm setting!
Tele Vue is still the leader in high performance, wide angle eyepieces for astronomy. There will always be cheap imitators, but astronomers the world over agree Tele Vue eyepieces are simply the best. One look is all it takes...come and see for yourself!
Tele Vue is known for its in-house eyepiece and telescope designs by Al Nagler; the development of the Ethos series brought new meaning to the term "in-house." The concept for this eyepiece series was 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 colour, angular magnification distortion correction, 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 protégé 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.

Owners of fast Dobsonian/Newtonians can enjoy a larger true field, free of secondary shadowing, than ever before. For example, a 12.5", f/4.5 scope with a Paracorr will deliver a 1.5 degree field (3 Moon diameters), at 53x with a 6mm exit pupil.

Tele Vue 22mm Nagler Type IV is the perfect eyepiece for longer focal lengths whether its an SCT or long focal length Dob, this a great eyepiece, however, in a short Refractor it offers supreme luxury in widefield viewing. The long 19mm eye relief makes it great for eyeglass wearers and the 82 degree apparent field gives that Tele Vue spacewalk feel that other eyepieces wish they had. Tack sharp right to the edge. all lenses are edge blackend to eliminate stray light and ghosting and threaded for your favourite filter. One of the ultimate deep sky experience awaits you.
The Nagler eyepiece was revolutionary as the first eyepiece to deliver breath taking wide fields of view while still providing sharp images from edge to edge.
The eyepiece is an extremely important, but often over looked element in the image your telescope delivers.
In contrast to the objective of your telescope which rarely covers an image angle of more than 2°, the eyepiece has to remain sharp over an angle of more than 50°...or a staggering 82° in the case of the Nagler. For this reason extreme care must be taken to correct for aberrations - especially away from the optical axis.
Astigmatism and field curvature are 2 factors that most influence the off axis sharpness especially in "fast" objectives (below f/6). Eyepiece designers had tried for many years to eliminate these aberrations but it was not until the 1980s that a breakthrough occurred - the Nagler eyepiece.
Since then Al Nagler has refined this series of eyepieces taking advantage of different exotic glasses and improved coatings to deliver quite simply the best performance you can get out of an eyepiece. While other manufacturers may boast impressive field sizes, Televue's philosophy of "showing no field unless it is fine" stresses full field image quality as the ingredient for impressive views.

Take a "spacewalk" across a wide, sharp 82° apparent field
Compare a penny to a half dollar to see the relative size between a 50° and 82° apparent field - almost 3 times the area difference! And while others boast of impressive apparent field sizes, Tele Vue's philosophy of "showing no field unless it's fine" stresses full field image quality as the ingredient for impressive views. Blackened lens edges, anti-reflection threads and rubber eyeguards deliver maximum contrast. Adapter skirts for 2" focusers on larger 1¼" models and rubber grip rings are additional Tele Vue "firsts". Even 2"/1¼" barrel models have an additional feature allowing the 2" extension tube (EBX-2120) to be screwed on, which permits use of 2" filters as well as 1¼". 100% full field visual inspection on our own flat-field test instruments guarantees the performance of every Tele Vue eyepiece.
Review
The TeleVue 22mm Nagler Type 4 is another of the newer improved Naglers.
The 19mm of eye relief as well as TeleVue's "Instadjust" click-stop adjustable-height eyeguard with a soft fold-down rubber eyecup allows for eyeglass wearers to experience a full 82° apparent field of view when fully retracted. The click stop increments of "Instadjust" allows non eyeglass wearer to find the exact height for full field of view images. A small plastic insert that fits in the eyeguard allows non eyeglass wearers to find the correct position of the exit pupil.
In big, fast Dobs this is an amazing medium-low power eyepiece great for open clusters, galaxy clusters and emission nebulae. Eta Carinae is totally awesome in this eyepiece.
In SCT's it offers 2.2mm exit pupil making images very bright and this is ideal for open and globular clusters. Have a look at the Tarantula Nebulae to be convinced how good this eyepiece is.

An excellent premium-quality medium power wide field eyepiece. It is an excellent eyepiece for resolving globular clusters, planetary nebulae and very good for galaxies.
The 19mm Panoptic would be a welcome addition to any serious deep space observer’s eyepiece collection.
It only has 10mm of eye relief so eyeglass wearers may consider the 18mm TeleVue Radian with it's 20mm eye relief. However the Panoptic provides a 30% larger field of view than 18mm Radians.

Early reviews of the Tele Vue DeLite 62° Apparent Field Eyepieces
Excerpt from Tom Trusock's March 2016 review in Astronomy magazine.
Eyepieces are a visual astronomer's window to the universe. And history shows that Tele Vue led the revolution in high-quality wide-field eyepieces with its introduction of the Nagler line in the early 1980s. Company founder Al Nagler was the driving force and principal optical designer on all eyepieces until the introduction of the Ethos line, when protégé Paul Delechiaie stepped up to the plate. Delechiaie went on to design the Delos line and, most recently, the DeLite line.
Tele Vue targeted the DeLites, introduced just before the 2015 Northeast Astronomy Forum convention, at observers looking for an economical high-end eyepiece that's small and light yet provides diffraction-limited performance, high contrast, and generous eye relief.
At night, contrast was superb, enabling me to make out fine detail within the planetary bands of Saturn. And in the rings, the Cassini Division was obvious though ... smaller scopes. The eyepieces showed no sign of scattered light or ghost images, and transmission was quite good. Also, I noted no glare or internal reflections. Although I tend to prefer using single eyepieces to achieve desired magnifications, that's not always possible. So, it was good to learn that these eyepieces worked well with Barlow lenses.
I then moved to other targets. Through the 6-inch, the gold and blue of Albireo (Beta <ß> Cygni) simply popped. Through the 18-inch, the Hercules Cluster (M13) was a jellyfish of suns against a deep-black background, and stars were pinpoint out to the edge of the field.
Tele Vue has once again created a line of all-around excellent eyepieces, good for both planetary and deep-sky work. Selling points are long eye relief, a small and light design, and the relatively inexpensive cost. The DeLite line should be on your must-view-through list of eyepieces at the next star party.

Excerpts from review in Sky at Night magazine.
This trio of parfocal lenses live up to their name -- they are a delight
The DeLite eyepieces deliver a fantastic image, free from aberration and very crisp -- exactly what a good eyepiece should do.
The lockable eyeguard and 20mm eye relief means that the DeLites are perfect for those who swap between wearing spectacles too.
Ultimately, the excellent design of the DeLites provides an eyepiece that you forget about. Instead you find yourself concentrating on the thing your telescope was pointed at, and this, after all, is what a telescope and its supporting optics are supposed to do.

Excerpts from Dennis di Cicco's "Quick Look" review of "Tele Vue's New DeLite Eyepieces" in Sky & Telescope.
WHAT WE LIKE
Upholds Tele Vue's reputation for optical excellence
Comfortable to look through
Adjustable eye guard with locking collar
Works with Dioptrx astigmatism corrector
While many of Tele Vue's recent eyepiece introductions have established new standards for the wide-field observing experience, the DeLites have far more modest specifications.
What makes the DeLites special, however, comes from looking through them.
I tried them with four scopes - a 12-inch f/4 Newtonian reflector fitted with Tele Vue's Big Paracorr coma corrector … a 12-inch f/5 Dobsonian; a 4-inch f/5.4 apo refractor, and a classic 6-inch f/9 Newtonian.
As I've come to expect from all of Tele Vue's eyepieces, the DeLites offered superb views. Stars appeared as pinpoints across the entire field; there wasn't a hint of false color around even the brightest stars; and there was only a touch of pincushion distortion, meaning that round objects won't stretch into ovals as you sweep them across the field. Daytime views were contrasty and without a trace of color fringes even at the borders of high-contrast objects such as power lines seen against a bright sky.
These are the features everyone looks for in a quality eyepiece, but the DeLites offered something more - something that I also found remarkable about the Tele Vue Delos eyepieces … . The DeLites are very easy to look through. You never get the feeling that you are struggling to get your eye perfectly aligned with the eyepiece. This comes as little surprise since Tele Vue acknowledges that the DeLite design evolved as a "smaller, more economical and lightweight version of the Delos." Even the name is a clever spin on a "lite" version of the Delos.

I then moved to other targets. Through the 6-inch, the gold and blue of Albireo (Beta <ß> Cygni) simply popped. Through the 18-inch, the Hercules Cluster (M13) was a jellyfish of suns against a deep-black background, and stars were pinpoint out to the edge of the field.
Tele Vue has once again created a line of all-around excellent eyepieces, good for both planetary and deep-sky work. Selling points are long eye relief, a small and light design, and the relatively inexpensive cost. The DeLite line should be on your must-view-through list of eyepieces at the next star party.

This trio of parfocal lenses live up to their name -- they are a delight
The DeLite eyepieces deliver a fantastic image, free from aberration and very crisp -- exactly what a good eyepiece should do.
The lockable eyeguard and 20mm eye relief means that the DeLites are perfect for those who swap between wearing spectacles too.
Ultimately, the excellent design of the DeLites provides an eyepiece that you forget about. Instead you find yourself concentrating on the thing your telescope was pointed at, and this, after all, is what a telescope and its supporting optics are supposed to do.

WHAT WE LIKE
Upholds Tele Vue's reputation for optical excellence
Comfortable to look through
Adjustable eye guard with locking collar
Works with Dioptrx astigmatism corrector
While many of Tele Vue's recent eyepiece introductions have established new standards for the wide-field observing experience, the DeLites have far more modest specifications.
What makes the DeLites special, however, comes from looking through them.
I tried them with four scopes - a 12-inch f/4 Newtonian reflector fitted with Tele Vue's Big Paracorr coma corrector … a 12-inch f/5 Dobsonian; a 4-inch f/5.4 apo refractor, and a classic 6-inch f/9 Newtonian.
As I've come to expect from all of Tele Vue's eyepieces, the DeLites offered superb views. Stars appeared as pinpoints across the entire field; there wasn't a hint of false color around even the brightest stars; and there was only a touch of pincushion distortion, meaning that round objects won't stretch into ovals as you sweep them across the field. Daytime views were contrasty and without a trace of color fringes even at the borders of high-contrast objects such as power lines seen against a bright sky.
These are the features everyone looks for in a quality eyepiece, but the DeLites offered something more - something that I also found remarkable about the Tele Vue Delos eyepieces … . The DeLites are very easy to look through. You never get the feeling that you are struggling to get your eye perfectly aligned with the eyepiece. This comes as little surprise since Tele Vue acknowledges that the DeLite design evolved as a "smaller, more economical and lightweight version of the Delos." Even the name is a clever spin on a "lite" version of the Delos.

An excellent premium quality low power wide field eyepiece. It is ideal for observing large emission and reflection nebulae, Supernova Remnants and large open star clusters.
It is well-suited for any telescope with a focal ratio of f/5 or longer offering 7mm exit pupil at f/5. Works wonderfully in SCT's for large field of view.
It has a huge 28mm of eye relief and can be used by eyeglass wearers with no vignetting of the field. This is a lot of eyepiece so its heavy weight may cause some minor concern in Dobsonians.
An excellent premium quality low power eyepiece. It is ideal for observing large emission and reflection nebulae, Supernova Remnants and large open star clusters.
It is very well suited to large f/4.5 Dobsonians giving 6mm exit pupil. Is a great low power eyepiece in short focal length refractors, for example, with the TV 102, it gives 31x and a true field over 130 arc minutes.
It has 16mm of eye relief and can be used by eyeglass wearers with no vignetting of the field. Images are sharp right to the edge of the field.
This is a lot of eyepiece so its heavy weight may cause some minor concern in Dobsonians. One of the favourite eyepieces of Bintel's Technicians.
The 24mm is designed to produce the largest true field possible in a 1-1/4" eyepiece.
Its 27mm field stop is the same as the 32mm Tele Vue Plössl. The higher power darkens the sky background while the greater magnification yields more details on extended objects. Further, its light weight, comfortable 16mm eye relief, and tapered top instantly make the 24mm Panoptic the ideal eyepiece for getting the maximum field for binocular viewers.
Review
This Sky & Telescope “Hot Product for 2003” is designed to produce the largest true field possible in a 1-1/4" eyepiece. (Its 27mm field stop is the same as the 32mm Tele Vue Plössl).
The higher power darkens the sky background while the greater magnification yields more details on extended objects. Further, its light weight (1/2 lb.), comfortable 15mm eye relief, and tapered top instantly make the 24mm Panoptic the ideal eyepiece for getting the maximum field for binocular viewers.
Great for emission and reflection nebulae, Supernova Remnants and large open star clusters.
Listed as a Sky and Telescope "Hot Product" when released, the 41mm Panoptic eyepiece is the big brother to the 24mm Panoptic (largest 1.25" field).
With its 46mm field stop, the 41mm Panoptic delivers the largest 2" field possible.
Because of its long focal length, it is brilliant in SCTs. It is ideal for observing large emission and reflection nebulae and Supernova remnants. The 19mm of eye relief means that eyeglass wearers can see the whole field of view with no vignetting. An adjustable and removable screw-type top allows quick, comfortable eye positioning. The scalloped shape gives a positive grip. It has a soft rubber eyecup for comfort which can be rolled down or left up.
The Tele Vue DeLite 11mm is a versatile medium focal length eyepiece. Generally eyepieces in the 9-15mm focal length range are excellent all-rounders. The DeLite 11mm could well be an ideal choice as your main high quality eyepiece.
Available in 18.2, 15, 11, 9, 7 and 5mm focal lengths, the DeLite series is a delightful addition to Tele Vue's visionary line of eyepiece developments. Named DeLite because that best describes the viewing experience, the name also recognizes designer Paul Dellechiaie's work.

Early reviews of the Tele Vue DeLite 62° Apparent Field Eyepieces
Excerpt from Tom Trusock's March 2016 review in Astronomy magazine.
Eyepieces are a visual astronomer's window to the universe. And history shows that Tele Vue led the revolution in high-quality wide-field eyepieces with its introduction of the Nagler line in the early 1980s. Company founder Al Nagler was the driving force and principal optical designer on all eyepieces until the introduction of the Ethos line, when protégé Paul Delechiaie stepped up to the plate. Delechiaie went on to design the Delos line and, most recently, the DeLite line.
Tele Vue targeted the DeLites, introduced just before the 2015 Northeast Astronomy Forum convention, at observers looking for an economical high-end eyepiece that's small and light yet provides diffraction-limited performance, high contrast, and generous eye relief.
At night, contrast was superb, enabling me to make out fine detail within the planetary bands of Saturn. And in the rings, the Cassini Division was obvious though ... smaller scopes. The eyepieces showed no sign of scattered light or ghost images, and transmission was quite good. Also, I noted no glare or internal reflections. Although I tend to prefer using single eyepieces to achieve desired magnifications, that's not always possible. So, it was good to learn that these eyepieces worked well with Barlow lenses.
I then moved to other targets. Through the 6-inch, the gold and blue of Albireo (Beta <ß> Cygni) simply popped. Through the 18-inch, the Hercules Cluster (M13) was a jellyfish of suns against a deep-black background, and stars were pinpoint out to the edge of the field.

Selling points are long eye relief, a small and light design, and the relatively inexpensive cost. The DeLite line should be on your must-view-through list of eyepieces at the next star party.

INNOVATION IN EVERY DETAIL
"CONSTANTLY IMPROVING WHAT IS GOOD"
This has been the SWAROVSKI OPTIK motto since day one. For Swarovski, this also means exceeding their customers’ expectations and surprising them time and again – with the precision of Swarovski's products, with their innovative technology and with their comprehensive service.
PRECISION GUARANTEED
Swarovski's products are manufactured with ultra precise tolerances of 8 μ, less than a hair’s breadth (approximately 60 μ). It is only through a combination of maximum precision, state-of-the-art technology and adherence to the high SWAROVSKI OPTIK quality standards that they are able to consistently and permanently assure the optical perfection for which SWAROVSKI OPTIK is renowned, including tazor-sharp, high-contrast images with maximum colour fidelity as a result of exclusively using high-precision lenses and prisms, and complete reliability from -20 °C / +55 °C.
QUALITY MANAGEMENT SYSTEM
To ensure a consistently high quality level in all their products, Swarovski subject every product and every phase of production to comprehensive, manual quality controls. Every product also undergoes a full image and material control. Swarovski's quality management system has been certified to ISO 9001/2000 since 1999. Their environmental management system has been certified to ISO 14001 since 2000.
SWAROVISION
The SWAROVISION technology redefined the concept of optical quality.
Field Flattener lenses provide unprecedented peripheral definition, fluoride-containing HD lenses minimize colour fringing, while optimized coatings ensure maximum colour fidelity.
Large eye relief offering a full field of view for those wearing eye glasses.
HD-OPTICS
Swarovski's HD optics feature fluoride-containing lenses, which virtually eliminate colour aberrations.
The scatter is considerably less with fluoride than with even the best types of optical glass.
This enables maximum colour fidelity and leads to a significant improvement in resolution and contrast
SWAROTOP AND SWARODUR
Coatings for bright, high-contrast images: Reduces surface light reflection from 4-6% to 0.2%.
Used on all the lenses and prisms found in SWAROVSKI OPTIK products.
SWAROBRIGHT
Coating for maximum colour fidelity across the whole light spectrum: SWAROVSKI OPTIK was the first manufacturer in the world to use this technology in series production.
SWAROCLEAN
This non-stick coating on the lenses makes it easier to clean away dirt such as water marks, insect repellents, or tree resin.
NEW FEATURES AND FIELDPRO PACKAGE
The launch of the EL binoculars by SWAROVSKI OPTIK marked a milestone in long-range optics. These binoculars have now been further enhanced following intensive development and a great deal of dedication. The result of these efforts is the best EL Family ever.
Completely redesigned strap and harness connection.
The new rotating strap connector with a cord adapts perfectly to any movement.
The bayonet catch enables you to fit and switch the carrying strap and accessories very quickly and flexibly.
With a simple turn of its practical quick catch button you can rapidly and silently adjust the carrying strap to the right length.
The objective lens covers blend aesthetically into the overall design and also remain securely attached to the binoculars thanks to the innovative connector.
The focusing wheel can also be used more easily, thanks to its softer, fully armored, and more slip-resistant design.
The diopter adjustment’s new lock function ensures that your personal settings cannot be changed.
PREMIUM QUALITY DOWN TO THE SMALLEST DETAIL
Like every product from SWAROVSKI OPTIK, all EL SWAROVISION binoculars are produced using the lowest possible production tolerances and undergo a 100% quality check. The 8x42 or 10x42 models of the EL 42 SWAROVISION binoculars are available in green. As standard, the binoculars also come with eyepiece and objective lens protectors, as well as a lift carrying strap.
Field flattener lenses: contrast right up to the image periphery
HD optics: maximum contrast & colour fidelity
Eye relief plus: 100 % field of view even for spectacle wearers
Maximum colour fidelity: through optimized coating of the lenses and prisms.
Swarovski's commitment to complete customer satisfaction is reflected in their comprehensive 10 year warranty. Should your binoculars develop a fault or be damaged, even outside the warranty period, you can be assured of service second to none.
Revolutionary optical performance, outstanding ergonomic design and perfect functionality. Swarovski EL binoculars embody absolute excellence in long-range optics.
Birders and nature lovers trust Swarovski EL 10x42 binoculars to share special moments in every exciting detail. For instance, have you ever watched a Wandering Albatross, an exceptionally gifted glider among water birds, letting itself be skillfully carried up high by the updraft? This is a moment that displays nature as majestic and commanding in its own absolute perfection, and you will want only the best set of optics to bring you closer.
Anyone who picks up a pair of EL Family binoculars can sense immediately that Swarovski Optik has been inspired by such sights. With these binoculars, future-oriented technologies meet master crasftsmanship. The result is an almost magical interaction between optics, ergonomics and functionality, rolled into a masterly crafted design that stands out with its subtle elegance from all competitors.
The new EL generation is also molded in this proud tradition. The crystal-clear optics provided by SWAROVISION technology and the unique ergonomic design, including the EL wrap-around grip, are enhanced by the new, perfectly harmonized FieldPro package. This offers an unprecedented level of comfort while birding and enjoying wildlife, thanks to the new carrying strap and objective lens and eyepiece covers.
