TeleVue Delos 10mm 1,25" (22172)

TeleVue Delos 10 mm 1.25" Eyepiece (Model 22172)

The TeleVue Delos 10 mm eyepiece belongs to a premium line of mid-to-short focal length eyepieces engineered for reference-level visual performance. With a 72° apparent field of view and a comfortable 20 mm eye relief, it delivers an immersive yet relaxed observing experience. Every optical, mechanical, and ergonomic detail has been carefully optimized to meet the highest standards for contrast, sharpness, and usability. It is ideal for detailed observations of the Moon, planets, and a wide range of deep-sky objects.

The Delos series was developed as a slightly narrower-field alternative to the Ethos design. By reducing the apparent field to 72°, the designers were able to extend eye relief and control pupil aberrations without making the eyepiece overly large. The result is edge-to-edge sharpness, extremely accurate distortion correction, and excellent color neutrality. Carefully matched glass elements, multi-coatings, and advanced anti-reflection treatments maximize brightness and image fidelity.

Contrast is further enhanced by a continuously adjustable and lockable eyeguard system. The large 35 mm diameter eye lens helps minimize stray light and unwanted reflections, improving perceived contrast. The sliding rubber eyeguard allows precise adjustment to suit individual viewing preferences, while indicator marks on the housing make it easy to return to a preferred setting. The eyeguard can also rotate for compatibility with Dioptrx systems.
