  • Tele Vue Delos Eyepieces

    "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 degree 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

    Tele Vue is pleased to introduce the Delos, mid-to-short focal length line of 20mm eye-relief, 72 degree 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 degree 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 degree (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.

    Outstanding eyepiece!

    This EP gives 100x and 2mm of exit pupil in my 8"f6 dob. The entire field is very sharp and the contrast is excelent. I really like the 20mm of eye relief of the Delos, even though I don´t wear glasses. The adjustable eyecup is very well made to achieve perfect eye placement and the 72º of AFOV is perfect for me. The body is this focal lengh isn´t particullary long, but be aware it´s on the heavy side (almost 0.5 kg) It performs very well with my 2x shorty barlow. Can´t go wrong with this one!


    OK thats it

    I have different makes of eyepieces that I think are better ,My Delos 12mm is hard to see through and find the target and when I do its not as clear as some of my other Eyepieces , Maybe just My Eyes but I don't see ( Get what you pay for on this one ) I call it as I see it or with this NOT SEE IT .
