Tele Vue EDL-17.3 overview

  • 1Description

Taking design inspiration from the venerable Ethos line but with a narrower field of view to provide users with a long more comfortable eye relief, the Tele Vue Delos 17.3mm Eyepiece was designed for easy long-duration lunar and planetary observation. Index-matched anti-reflective multi-coatings applied to the glass lenses were engineered specifically to maximize light transmission, which produces sharp, bright, high-contrast, and color-faithful images across the entire spacious 72° apparent field of view. Its adjustable-height rubber eyecup helps to further enhance contrast by preventing stray light from entering the user's peripheral vision, which can interfere with the image seen through the ocular. The eyepiece is offered with a 1.25" diameter barrel for compatibility with a wide variety of filters and accessories.

    Rated 5 out of 5 by from Clear and comfortable This is becoming my go-to eyepiece to start viewing most things, because of its clarity and relatively wide AFOV. I really like the the eye relief and the flip-up eye ring. Will definitely be purchasing others from this family of eyepieces!

    Rated 5 out of 5 by from Excellent eyepiece! I just added the 17.3 Delos to my e.p's and it is superb..the clarity is just stunning. I have the 10mm, 6mm and now the 17.3. The wide a.f.o.v. really makes this a winner for me and as I wear glasses the 20mm of eye relief is a great help in making my observing a comfortable experience.Highly recommended !

    Rated 5 out of 5 by from Delos is good for me. Owned about every eyepiece TeleVue made until the Delos. Always something different and the Delos model is no exception. I like the way the eyepiece adjusts over the objective. The twisting of the barrel and the way it tightens up gives a feeling of ownership. It is heftier than the Radian line and a bigger field. It is priced right but the view is soft like an Ethos and the field is big enough. Even the box is up to date with plenty of foam.

    Rated 5 out of 5 by from Sweet Piece of Glass Exceptional viewing. I recommend using it with a parracor. Exceptional quality in the construction with a nice heft and feel.
