Tele Vue's Delos 4.5mm is a short focal length eyepiece that will deliver high power magnification. 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. High powered views without the need for a Barlows or Powermate!

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 4.5mm has a standard 1.25" barrel making it suitable for almost any telescope or even bino-viewers!

Tele Vue Delos 4.5mm - Specifications

Model # EDL-04.5
Focal Length 4.5mm
Barrel Size 1.25"
Apparent Field of View 72°
Eye Relief 20mm
Weight 499g
Field Stop 5.6mm

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.

Sky & Telescope Hot New Product for 2012 Award

More Than Expected (Delos 6 and 10mm)
And while the 20 mm of eye relief make them attractive for those who were wearing eyeglasses, it was the "distinctly pleasurable" observing experience that most impressed our reviewer. When it comes to eyepiece design, The Delos seems to have hit all the sweet spots.

Excerpt from ATT review of Delos 6- & 10-mm eyepieces:

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. Bottom line: If you're in the market for a planetary eyepiece, you owe it to yourself to consider the Tele Vue Delos.

Review of the 6mm & 10mm Delos from Astronomy Magazine, December 2011

The contrast was excellent - right up there with some of the best planetary eyepieces 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.
Tele Vue has constructed an eyepiece that stands with the best deep-sky and planetary eyepieces on the market.

Excerpts from Sky & Telescope, June 2011, review of Delos eyepieces:

WHAT WE LIKE:

Essentially perfect optics
"Immersive" observation experience

WHAT WE DON'T LIKE:

I spent several nights viewing the Moon, Saturn, stars, and nebulae with a variety of telescopes

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. The view, especially during the daytime, is very pure with no noticeable color tint. And there wasn't a hint of ghosts or reflections, even with the brightest stars".

"What caught me a bit off guard, however, was something that's best described as the observing experience. It was distinctly pleasurable."

"I have the sensation of looking out of a circular window rather than into an eyepiece."

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.

Concept The Nagler Type 7 series was developed as a natural extension of our highly regarded, 85°, limited edition Apollo 11 eyepiece. However, the series can also be thought of as an extension of the long eye relief Nagler Type 4 concept. With the all-new Type 7 design layout, we achieved our goal of Apollo 11-like performance across a series of focal lengths that are eyeglass friendly.

Design Goals The design goal was simple. The performance of each of the Type 7 focal lengths must equal or exceed that of the Apollo 11 eyepiece in the areas of full-field sharpness, contrast, distortion correction, eye relief, and pupil comfort, but across an 82° apparent field of view instead of 85°.

Design Details If you have been waiting for a Nagler series for eyeglass wearers, the Type 7 is it. Combining the expansive 82° apparent field of view with 19 mm of eyeglass friendly eye relief, and large eyelens, the Nagler Type 7s give a new dimension to the "spacewalk" viewing effect. An easily adjustable, locking eye-guard is included for those who don't wear eyeglasses. It helps to correctly position your eye to the exit pupil so you don't get too close to the eyelens, as well as blocks contrast-robbing stray light from interfering with the view. Speaking of which, of course we've applied all the optical coating and baffling features Tele Vue eyepieces are known to maximize contrast and complement the fully corrected field; revealing beautifully natural star colors with pinpoint sharpness. The optical layout affords unrivalled parfocality throughout the four focal lengths and even between 1¼" and 2" modes when used with the Tele Vue Hi-Hat 1¼" and 2" adapter (ASF-8125). The Type 7 series is also parfocal with all other 1¼" Tele Vue eyepieces (except 40 mm Plössl) when those eyepieces are used in the Tele Vue Hi-Hat 1¼" and 2" adapter (ASF-8125). Available in focal lengths of 5.5, 9, 14, and 19-mm, the Type 7s complement the 22-mm Type 4 and 31 mm Type 5 as eyeglass friendly Naglers.

The Nagler Type 7 models all weight 19 to 21 oz / 540 to 590 gm.
