10mm Hyperion eyepiece with 68° field

The Baader Planetarium 10mm Hyperion Modular Eyepiece is a new astronomical eyepiece designed for visual observation through telescopes. It provides a wide 68° apparent field of view and 20mm of eye relief for comfortable extended viewing sessions. The modular design accepts both 1.25" and 2" focusers.

Suits observers wanting wide fields

This eyepiece suits observers who want a wide 68° field and generous 20mm eye relief for comfortable planetary and deep-sky viewing. It does not suit setups restricted to 1.25" focusers only, nor users who require a narrower field or shorter eye relief for specific applications.

68° apparent field of view

The single specification that decides fit is the 68° apparent field of view combined with 20mm eye relief at 10mm focal length. This combination determines whether the eyepiece matches the observer's desired magnification and viewing comfort for their telescope's focal ratio.

Questions about this item

Does the 1.25" barrel limit the true field of view at 68°?

The 1.25" barrel accepts the 10mm focal length with a 68° apparent field, so the true field is set by your telescope's focal length.

What focuser sizes will the modular body fit?

The eyepiece fits both 1.25" and 2" focusers using its modular design.

How do I attach a camera for afocal imaging with this eyepiece?

Remove the rubber eyeguard to expose the internal thread, then screw on a compatible Baader adapter for your camera.
