Tele Vue Delos 12mm Planetary Telescope Eyepiece EDL-12-0 is a high performance eyepiece designed for looking at planets through a wide range of telescopes. TeleVue has redesigned every optical, mechanical, and ergonomic aspect on the eyepiece to achieve reference-standard performance for any visual application. This Televue telescope accessory was conceived as a narrower field Ethos eyepiece; Tele Vue Optics has reduced the field of view to 72° and increased the eye-relief while controlling pupil aberrations, all without making the eyepiece too large. Using the high performance Ethos eyepieces as a starting point, the design of the TeleVue Optics Delos 12mm Telescope Eye Piece achieves full field sharpness, virtually perfect fθ distortion mapping, and color neutrality. Image fidelity is maximized utilizing glass-matched multi-coated lenses and anti-reflective surfaces throughout the Tele Vue Optics Delos 12mm Focal Telescope Eye Piece for Planets.

Contrast is further enhanced on the Tele Vue Optics Delos 12mm 72° Apparent Field Telescope Eye-Piece with a new, continuously adjustable height eyeguard system that can be locked in any position. Since the eye lens of the Televue telescope accessory is a large 35mm 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 Televue Delos 20mm Eye Relief 12mm Focal Length Telescope Eyepiece features a sliding action eye guard that allows you to position 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. View planets with extraordinary comfort and detail when you use the Tele-Vue Optics Delos Full Field 12mm Tele-Scope Eyepiece.
