Product Info
Manufacturer Description
Tele Vue is pleased to introduce 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.
All Tele Vue Delos eyepieces have proprietary tuned full multi-coatings, blackened lens edges, high index glasses, fold-down eyeguards, rubber grip rings, cover for the eyeguard, an undercut in the barrel for extra locking security, and filter threads. The Delos eyepieces are parfocal up to the focal length of 12mm within the series, and with several other TeleVue eyepieces. All Tele Vue eyepiece lines are proprietary, in-house designs manufactured to their specifications and tolerances. Every eyepiece is individually tested at Tele Vue to ensure it meets high optical and cosmetic standards.
Concept: "It was natural to take lessons learned from the tremendously successful Ethos project and apply it going forward. In the fall of 2008, Paul Dellechiaie was tasked to investigate a long eye-relief eyepiece design in the 70° AFOV range, retaining the key performance goals met with Ethos. My father named Paul's design, "Delos." Delos is a beautiful Greek island which happens to be the mythical birthplace of Apollo, god of light. More importantly the name was chosen to give recognition to Paul, principal designer of both Delos and Ethos." — David Nagler

Oct 31, 2014The best 72 AFOV eyepiece ever made....!
Pros:Easy to Use,Quality Lenses,Strong Construction
Cons: Comments:This eyepiece produces 100X in my scope. My first target was Orion nebula. WOW.... I was amazed with the clarity and the detail it produced. Trapezium was stunning and I was able to see the green and blue ting in M42.
Bottom Line: Would you recommend this item? Yes
This eyepiece has a adjustable eye guard and it is very easy to adjust according to our preference. Some folks says it is difficult to get the proper eye positioning but after few minutes it will become one of your second natures.
I wholeheartedly recommend this eyepiece to anyone who is willing to have the best views of planets and DSOs.....!This review was provided courtesy of AgenaAstro.com
