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

      5.0 Amazing clarity

      Pros:

      Cons:

      Comments:

      I am a member of our local astronomical society and have used barrowed TeleVue lens delos and ethos and they never fail to give a great view. The image clarity, color, and contrast is truly amazing compared to my other eyepieces. I now own both a Panoptic 24 and this Delos 10 and both eyepieces are exceptional. They are very expensive but if you can afford one, get one. You wont be disappointed. Wearing glasses I appreciate the sliding eye guard on the delos. I am using this with my Celestron Evo 9.25 and was rewarded with a spectacular view of Jupiter, its cloud bands, and the great red spot the other night. My other eyepieces couldn't come close to revealing the detail seen in the Delos. I will definitely be adding another Delos to my collection. Highly recommended.

      5.0 Great Eye Piece

      Pros:

      Cons:

      Comments:

      I use binoculars that take 1.25 eye pieces. I purchased the Delos as an addition to one I already have (I use Delos with my scope as well). I find this eye piece to have the right field for my eye, and it is a great item for any collection.

      5.0 TeleVue 10mm Delos

      Pros:

      Cons:

      Comments:

      Like all of TeleVue products, the construction, fit and finish of this eyepiece is first class. The optics are flawless with a sharp field from edge to edge in my C8 and 10" Skywatcher dob. The Delos series of eyepieces with thier 72 degree AFOV and 20mm eye relief are a joy to use with or without glasses. What I really like though, is the sliding eyecup. You can adjust it just right and lock it in place. This eyepiece is never leaving my EP case.

      5.0 Choose the best things. And of them - what is available!

      Pros:

      Accurate,Easy to Use,Quality Lenses,Comfortable,Strong Construction,Lightweight

      Cons:

      Comments:

      This eyepiece has become the perfect addition to my telescope Lightbridge F/5 12". When observing deep-sky objects through the eyepiece, I am very glad to see the high contrast of the image and feel comfortable. Now visible are the DSO, which before I only planned on the maps of the sky. The moon and Jupiter (Delos 10mm + 2x Barlow lens) - fantastically sharp!
      Thanks Agenaastro-team for the sale of great things for my hobbies and fast shipment!

      Strong Construction,Quality Lenses,Lightweight,Accurate,Easy to Use,Compact

      Cons:

      Comments:

      This is a great eyepiece for eyeglass wearers. I also purchased the 6-14-17.3. Plan on adding the 8. Works very well in my 10" dob and 4" triplet refractor. Clear edge to edge. You can't go wrong. Also Agena's service is second to none.
