TeleVue 1.25" Eyepiece DELOS 17.3 mm - 72° Field

Tele Vue is pleased to introduce the Delos, mid-to-short focal length line of 20 mm 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 35 mm 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.
