Tele Vue Delos 17.3mm Eyepiece (1.25")

Taking design inspiration from the venerable Ethos line but with a narrower field of view to provide users with a longer, more comfortable eye relief, the Tele Vue Delos 17.3mm Eyepiece was designed for easy long-duration lunar and planetary observation. Index-matched antireflective multicoatings applied to the glass lenses were engineered specifically to maximize light transmission and produce sharp, bright, high-contrast, and color-faithful images across the entire spacious 72° apparent field of view. The rubber eyecup has an adjustable height to further enhance contrast by preventing stray light from entering your 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 .
