TeleVue Delos 24mm – 72° Wide-Angle Eyepiece

TeleVue Delos 24mm: 72° Wide-angle eyepiece: Delos eyepiece with 72-degree field of view

The Delos 24 mm is the latest addition to the series and the only one with a 2-inch thread. TeleVue showed it in April 2025 and delivered it starting in the autumn of that year.

It is also the only model with a 22 mm eye distance instead of 20 mm. For wearers who want to see the entire field, this is the widest option that TeleVue offers in this series.

72 degrees with a long eye relief

The Delos series is designed as a narrower Ethos field with more space behind the eyepiece. By keeping the field of view at 72 degrees, TeleVue was able to reduce the eye distance to 22 mm without the eyepiece becoming unwieldy.

For eyeglass wearers, that's the difference between seeing the full field of vision and missing a part of it. Even without glasses, you're looking more relaxed because your eye doesn't have to push against the lens.

What the 2 inch punch delivers

With an effective field stop of 29.6 mm, this eyepiece exceeds the limits of what a 1.25 inch objective allows. The true field of view is therefore noticeably larger than with the 17.3 mm, at a still modest magnification.

The ocular is parfocal with most 1.25-inch TeleVue oculars when used with the HiHat adapter. Due to its size and weight, this model is not intended for use in a binocular.

Interpupillary distance and adjustable eyecup

The eyecup is steplessly adjustable in height and lockable in any position, with index markings so you can find a previously found position. This ensures your eye's pupil is always in the same position relative to the telescope's exit pupil.

That's more than comfort. A misplaced eye causes edge discoloration and shadows in the image. With a fixed, repeatable eye position, that problem is gone, even during long sessions.

In your telescope

In a telescope with a 1200 mm focal length, this eyepiece provides approximately 50x magnification with a true field of view of approximately 1.41 degrees. For your own telescope, calculate this using the field stop: where field of view = 57.3 x field stop divided by the telescope's focal length.

The effective field of view of this model is 29.6 mm. That number determines how much of the sky you actually see, not just the focal length alone.

Included

• Height-adjustable, lockable eyepiece
• Dust caps for objective and eyepiece lenses
• Filter thread abandoned

Featured accessories

This series accepts TeleVue Dioptrx, which allows you to correct your own astigmatism without glasses. For higher magnifications without sacrificing eye relief, use a Powermate. With a fast parabolic Newtonian, the Paracorr corrects for mirror coma, something no eyepiece alone can solve.
