Tele Vue Eyepieces
Tele Vue Optics has been thrilling customers since 1979. The company founder, Al Nagler, put his lifelong love of amateur astronomy to work as a professional optical designer in 1958. His involvement in designing NASA lunar landing simulators directly influenced the Tele Vue products of today. Al wanted his own observing equipment to deliver that limitless starry vista usually reserved for astronauts. Tele Vue has continued to push to realm of what is possible. They've produced more compact, lightweight, and economical versions of classic eyepieces. The revolutionary Ethos, Panoptic, Delos and DeLite series range of eyepieces is huge. Powermate and Barlows extend the abilities of other quality eyepieces as well. There's something for every die-hard amateur astronomer. The eyepiece is half of your telescope! Upgrades and improvements will help you see more clearly.

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.

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.
Check out the rest of the Panoptic range.

Review
This is a very good medium to low power eyepiece for viewing smaller emission and reflection nebulae, open clusters and for resolving stars in many globular clusters.
It can be used for low power lunar observing or even the planets. The rubber grip give sure grip and makes it comfortable to use in cold weather.
The 17mm eye relief makes it very comfortable to use and is a great eyepiece to barlow.
The 25mm TeleVue Plössl was top-rated in a recent test report of 31 eyepieces in Sky & Telescope magazine as being the best in its focal length.
Like all TeleVue Plossls it has filter threads to fit your filters and blackened lens edges as well as being parfocal.

TheTele Vue Plossl 32mm has been around for decades and is still one of the best eyepieces on the market.
With 22mm of eye relief it suits every observer, even with eye glasses the full field of view the Tele Vue Plossl 32mm offers is superb.
Great eyepiece for larger clusters and nebulae.
Crisp and sharp from edge to edge with the same true field of view as the 40mm Plossl but with higher magnification.
Edge blackend lenses and thread barrel to take standard 1.25" filters.
Everyone should own a Tele Vue Plossl 32mm at some stage in their astronomy life.
Televue's 32mm Plossl is a favourite for those wanting to upgrade to a quality low power eyepiece. Certainly one of the best simple eyepieces ever made.

Review
This is a very good low power/wide field eyepiece for ideal or large open clusters, emission and reflection nebulae, or large extended objects that require a big field of view, perfect for scanning the Milky Way star clouds in Scorpius- Sagittarius from a dark sky site
The rubber grip gives sure grip and makes it comfortable to use in cold weather. As with all TeleVue eyepieces all edges are edge blackened.
This one of the Classic eyepieces to own offering improved edge-to-edge sharpness, and a wider and brighter field of view to the standard 25mm eyepiece that comes with most telescopes.. The 22mm of eye relief offers unvignetted viewing for eyeglass wearers.
It is parfocal with the shorter focal length Plossls.
The 32mm Plossl, with its larger 50 degree apparent field, will deliver the same true field as the 40mm but with higher magnification. Filter threads to fit your filters.

The faster the focal ratio of your telescope, the greater your visual reward for using Tele Vue eyepieces. Tele Vue Plössls feature full multicoatings 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 undriven mounts to gaze longer before repositioning the image.
The 25mm, 20mm, 15mm, 11mm and 8mm Plössls round out the focal lengths for various observing from deep sky to planetary. They work best with Tele Vue Barlows or Powermates to effectively double the number of focal lengths in your collection.
Far superior to eyepieces usually provided as standard with most instruments.
Review
This is a very good medium power eyepiece for lunar observing, resolving globular clusters, picking up detail in the more compact emission and reflection nebulas, etc.
This 15mm focal length is a very good in between power eyepiece, filling the gap between the 25mm eyepiece that comes standard with most scopes and a high power eyepiece.
It has 10mm eye relief . Like all TeleVue Plossls it has filter threads to fit your filters and blackened lens edges as well as being parfocal.

Review
This is a very good medium high to high power eyepiece for resolving globular clusters, lunar and planetary detail, some smaller galaxies (depending on aperture).
It has 8mm of eye relief and so eyeglass wearers may wish to remove their spectacles.
This 11mm TeleVue Plössl was rated the best 10 -12mm Plossl in a recent test report of 31 eyepieces in Sky & Telescope magazine.
Like all TeleVue Plossls it has filter threads to fit your filters and blackened lens edges as well as being parfocal.

Like any Tele Vue eyepiece, the Tele Vue DeLite 7mm produces images rich in detail and popping with contrast. The Tele Vue DeLite 7mm would make a great higher powered eyepiece in most cassegrain telescopes. With a generous 62° AFOV and 20mm eye-relief the viewing experience will be very comfortable.
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 recognises designer Paul Dellechiaie's work.

Reviews
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.

-
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.

Nagler Type 5
With the 31mm, the unique 6-element design using four exotic glasses, maintains the contrast advancement of the Type 4s while achieving a true field area 82% larger than the 22mm Type 4!
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.
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.

Review
This is a very good medium high to high power eyepiece for observing lunar and planetary detail, resolving globular clusters, small planetary nebulae .
It has only 6mm of eye relief that will limit the field for eyeglass wearers.
This 8mm TeleVue Plössl was rated the best 8mm Plossl in a recent test report of 31 eyepieces in Sky & Telescope magazine.
Like all TeleVue Plossls it has filter threads to fit your filters and blackened lens edges as well as being parfocal.

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.

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.

Tele Vue's Delos 10mm is a short to medium focal length eyepiece that will deliver amazing detail. Importantly though it still achieves a generous 20mm eye-relief and wide 72° apparent field of view. Amazing in well corrected refractors with short to medium focal lengths. The Delos 10mm is suitable for any focal length telescope. Some of the shorter focal length Delos eyepieces may provide too much power in long focal length Cassegrains. For example in an 8" f/10 telescope the 10mm Delos provides 200x magnification with eye-relief galore!
There is a good chance the TeleVue Delos will be seen as the ultimate combination of performance, viewing comfort and price. If you've been keeping a spot in your case for an affordable, premium eyepiece, you should consider a Delos - you won't be disappointed! Lessons learned from the tremendously successful Ethos series were applied to develop this long eye-relief, 72° apparent field of view eyepiece line.
The Delos 10mm for a standard 1.25" barrel diameter making it suitable for almost any telescope or even bino-viewers!

In 2011 Tele Vue introduced the Delos, mid-to-short focal length line of 20mm eye-relief, 72° apparent field of view eyepieces. Every optical, mechanical, and ergonomic aspect was rethought to achieve reference-standard performance for any visual application.
The Delos was conceived as a narrower field Ethos. Reducing the field to 72° allowed freedom to increase eye-relief, while controlling pupil aberrations, all without making the eyepiece too large. With Ethos performance standards as benchmarks, the Delos design achieves full field sharpness, virtually perfect f θ (theta) distortion mapping, and color neutrality. Image fidelity is maximized utilizing glass matched multicoatings and anti-reflection surfaces throughout the eyepiece.
Contrast is further enhanced with a new, continuously adjustable height eyeguard system that can be locked in any position. Since the Delos eye-lens measures a quite large 35mm in diameter, preventing stray light from reflecting off the first surface and extraneous light from entering your eye pays off in a nice increase in perceived contrast. The eyeguard's sliding action allows for positioning the soft rubber eyeguard at the ideal height to suit the observer's preference. Indicator marks on the eyepiece body are handy reference guides for setting your perfect position. The eye-guard can also rotate for Dioptrx users.

Wide-Field Eyepieces That Pack a Planetary Punch
With the Delos, the eyepiece simply "disappears" and allows the observer to observe. I could find nothing whatsoever to complain about; the "twist and tighten" eye relief adjustment feature is the best I've ever seen in any eyepiece, and the optics are essentially perfect. Tele Vue somehow always finds a way to continuously improve upon their eyepieces and the Delos is certainly no exception. Bottomline: If you're in the market for a planetary eyepiece, you owe it to yourself to consider the Tele Vue Delos.

- Contrast was excellent - right up there with some of the best planetary eypeices I've ever used.
- I searched but saw no internal reflections or scattering in either eyepiece.
- The flat field the Delos eyepieces produce really made star fields pop. Open clusters epitomized the old standard "diamonds on velvet". Stars on and off axis showed no sign of astigmatism.

Review This is a very good medium power eyepiece for lunar observing, resolving globular clusters, picking up detail in emission and reflection nebulas, etc.
The rubber grip give sure grip and makes it comfortable to use in cold weather.
The comfortable 14mm eye-relief is suitable for those wearing glasses .
Like all TeleVue Plossls it has filter threads to fit your filters and blackened lens edges as well as being parfocal.

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.

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 DeLite 5mm is one of the 3 newest additions in the DeLite series. Revealed at the NEAF conference in April 2016 the Tele Vue DeLite 5mm is sure to become a favourite in any eyepiece collection.
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. The Tele Vue DeLite 5mm is the shortest focal length available in the series and would be a great choice for planetary and lunar observing.

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.

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. In contrast to the objective of your telescope which rarely covers an image angle of more than 2°, Nagler eyepieces remain sharp over an angle of 82° to truly inspire a spacewalk vista. For this reason extreme care must be taken to correct for aberrations - especially away from the optical axis.
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, Tele Vue's philosophy of inspiring spacewalk vistas always keeps their optical devices well ahead of the pack.

This is a very good low power/wide field eyepiece. With 43 degree apparent field it provides the widest field possible from a 1.25” eyepiece. It's ideal for large open clusters, emission and reflection nebulae, large and faint nebula remnants such as the Vela Supernova Remnant and galaxy clusters.
The rubber grip gives sure grip and makes it comfortable to use in cold weather.. Better suited to the longer focal ratios of refractors, Schmidt-Cassegrains, and Maksutov-Cassegrains than it is to reflectors with focal ratios shorter than f/6.
In scopes that are longer than f/6, it will give you the widest and brightest field possible from a 1.25” focuser telescope.
The 28mm of eye relief makes it a good choice for eyeglasses wearers. It' s parfocal with the shorter focal length Plossls. Filter threads to fit your filters and blackened lens edges.

Tele Vue's Delos 14mm is a medium focal length eyepiece that creates an “immersive viewing experience”. With its generous 20mm eye-relief and wide 72° apparent field of view you will be hard pressed to find another eyepiece that is such a pleasure to look through. Amazing wide fields of view in well corrected refractors with short to medium focal lengths (over 1° FOV up to 1000mm focal length). While some of the shorter focal length Delos eyepieces may provide too much power in long focal length Cassegrains, the Delos 14mm is suitable for any focal length telescope.
There is a good chance the TeleVue Delos will be seen as the ultimate combination of performance, viewing comfort and price. If you've been keeping a spot in your case for an affordable, premium eyepiece, you should consider a Delos - you won't be disappointed! Lessons learned from the tremendously successful Ethos series were applied to develop this long eye-relief, 72° apparent field of view eyepiece line.

The Delos eyepieces are "easy to look through … . They have flat fields, delivering absolute pinpoint stars from edge to edge with no hint of color aberration.

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.

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 17mm 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 Tele Vue ETHOS 17mm is an ideal complement to the 31mm Nagler Type-5. They are parfocal (both have focus locations about 10mm above shoulder) and the 31mm Nagler Type-5 has exactly twice the true field area.

Tele Vue's Delos 12mm is a medium focal length eyepiece that creates an "immersive viewing experience". With its generous 20mm eye-relief and wide 72° apparent field of view you will be hard pressed to find another eyepiece that is such a pleasure to look through. Amazing wide fields of view in well corrected refractors with short to medium focal lengths (over 1° FOV up to 800mm focal length). While some of the shorter focal length Delos eyepieces may provide too much power in long focal length Cassegrains, the Delos 12mm is suitable for any focal length telescope.
There is a good chance the TeleVue Delos will be seen as the ultimate combination of performance, viewing comfort and price. If you've been keeping a spot in your case for an affordable, premium eyepiece, you should consider a Delos - you won't be disappointed! Lessons learned from the tremendously successful Ethos series were applied to develop this long eye-relief, 72° apparent field of view eyepiece line.
The Delos 12mm has a 1.25" barrel making it suitable for almost any telescope or even bino-viewers!

- Eye Relief 20mm
- Weight 408g

Background:
In 2011 Tele Vue introduced the Delos, mid-to-short focal length line of 20mm eye-relief, 72° apparent field of view eyepieces. Every optical, mechanical, and ergonomic aspect was rethought to achieve reference-standard performance for any visual application.
The Delos was conceived as a narrower field Ethos. Reducing the field to 72° allowed freedom to increase eye-relief, while controlling pupil aberrations, all without making the eyepiece too large. With Ethos performance standards as benchmarks, the Delos design achieves full field sharpness, virtually perfect f θ (theta) distortion mapping, and color neutrality. Image fidelity is maximized utilizing glass matched multicoatings and anti-reflection surfaces throughout the eyepiece.
Contrast is further enhanced with a new, continuously adjustable height eyeguard system that can be locked in any position. Since the Delos eye-lens measures a quite large 35mm in diameter, preventing stray light from reflecting off the first surface and extraneous light from entering your eye pays off in a nice increase in perceived contrast. The eyeguard's sliding action allows for positioning the soft rubber eyeguard at the ideal height to suit the observer's preference. Indicator marks on the eyepiece body are handy reference guides for setting your perfect position. The eye-guard can also rotate for Dioptrx users.

Tele Vue Ethos 8mm
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.
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.

Quotes from review of 10mm, 4.5mm, & 14mm Delos on Alpha Lyrae website.
- The stunningly flat field and lack of optical aberrations really allow clusters to shine and galaxies and nebulae are resplendent.
- It is rare I use any other eyepiece for deep sky observing anymore.
- Quite simply, the planetary performance matches the very best dedicated planetary eyepieces I have ever used such as the TMB Super Monocentric.
- There is also an indescribable quality which makes them a very easy and relaxing eyepiece to use.
