TeleVue Delos Eyepiece

The TeleVue Delos eyepiece was conceived as a narrower field Ethos. By reducing the field to 72° it made it possible to increase eye-relief, while controlling pupil aberrations, and all without making the eyepiece too large.

With Ethos performance standards as benchmarks, the Delos design achieves full field sharpness, virtually perfect f8 (theta) distortion mapping, and color neutrality.

Image fidelity is maximized utilizing glass matched multicoatings and anti-reflection surfaces throughout the eyepiece.

Contrast is even further improved upon with a new, continuously adjustable height eyeguard system that can be locked in any position.

Because the Delos eye-lens measures a rather large 35mm in diameter, which prevents stray light from reflecting off the first surface and extraneous light from entering your eye, pays dividends by a decent 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, whilst the eye-guard can also rotate for Dioptrx users.
