The Baader Hyperion 17 mm eyepiece offers a generous 68° apparent field of view—roughly as much as the eye can take in without moving.
Its 8-element optical design in five groups delivers sharp, colour-error-free images across the entire field of view, with a comfortable 20 mm eye relief. Thanks to its modern glass types and special anti-reflection coatings, it provides exceptionally high light transmission and colour fidelity. Internal anti-reflection threading eliminates ghost images.
After removing the eyecup, an M43x0.75 thread is accessible at the top of the eyepiece for attaching various cameras; an M43/T2 adapter is required.
The eyepiece provides a similarly wide area of sky as a longer focal length Plössl eyepiece, while its higher magnification makes celestial objects appear more impressive. The eyepiece focal length can optionally be adjusted using fine tuning rings or 2” Baader filters.
The eyepiece is compatible with both 1.25” and 2” focusers.
