1x Baader HYPERION Wide Angle Eyepiece 17mm Top Quality Wide Angle Eyepieces - both for visual and photographical applications

 

 

Baader HYPERION Eyepieces were designed both for visual and photographical applications and excel in both fields. They offer an excellent performance in all fields of amateur astronomy at a sensational price.

Properties - Visual Use:  

68° Apparent Field of View A comfortable and large field of view - easily visible even with eyeglasses. A field of view of 68 degrees has been tested as being ideal for astronomical observations. It is the largest field of view that can be viewed without strain and without turning your eyes.
Excellent Image Sharpness Both on axis and over the entire visible field these eyepieces offer an excellent image sharpness. Even short focal ratio Newtonians at an extreme f/4 offer great, sharp stars over the entire field.
Very Good Light Throughput and Contrast Hyperion eyepieces have an excellent multi-layer coating on each glass-to-air surface. Blackened lens edges and a blackened interior of the eyepiece body further reduce internal reflections and ghost images. The result is a bright image, no internal reflections and a very good contrast.
No Kidney-Beaning Cheap eyepieces and too extreme wide angle eyepieces often suffer from "Kidney-Beaning". When you move the head only slightly a black, kidney-shaped shadow will cover a part of the field of view. This effect is avoided in the Baader Hyperion eyepieces by use of oversized lenses.
Suitable for Use in Binocular Viewers Hyperion eyepieces are very well suited for binocular viewing. With an interpupillary distance of 56mm or more you will have no trouble looking through both eyepieces at the same time without getting into a conflict with your nose. A low focal plane allows you to reach focus more easily.
1.25" and 2" Dual Barrel Hyperion eyepieces do not only have a 1.25" barrel. The lower part of the eyepiece body is built as an additional 2" barrel. For use in 2" star diagonals you should check that the 1.25" barrel doesn't hit the mirror, though.
One Eyepiece - Two Focal Lengths By removing the 1.25" barrel with the first group of lenses you turn the Hyperion eyepiece into a 2" wide angle eyepiece with the standard M48 filter thread. A much lower magnification and larger true field of view is the result. You should know that the optical quality suffers by this, though! The eyepiece can then be used as an eyepiece for finding objects, but is not recommended for regular observations.

 

Specifications:  

Field of View apparent field of view 68° - nearly undistorted field
Eye Relief approx. 20mm
Lens Layout 8 Lenses - 5 Groups
Coating Full Multi-Layer Coating - blackened lens edges, blackened inside of eyepiece body
Threads and Barrel Sizes Eye & Camera Side Threads: - M43 x 0.75 thread - M54 x 0.75 thread Telescope Side Barrel Sizes & Thread: - 1.25" and 2" barrel - 1.25" filter thread in the 1.25" barrel - with 1.25" barrel and first group of lenses removed you also have the 2" filter thread (M48x0.75))

 

Properties - Photographical Applications:  

Simple and Strong Screw-On Camera Adaptation

Each Hyperion eyepiece has an M43x0.75 and an M54 thread near the eye lens. We offer nearly any conceivable adaptation on T2 or your camera's filter thread. Just let us know which exact camera you have and we will suggest the best adaptation.

Suitable For Heavy Cameras

The eyepiece body is made of metal, as are the precise threads. You can attach even heavy cameras securely.

One Eyepiece - Two Magnifications

By removing the 1.25" barrel with the first group of lenses you turn the Hyperion eyepiece into a 2" wide angle eyepiece with the standard M48 filter thread. A much lower magnification and larger true field of view is the result, well suited for taking images of extended nebulae and galaxies. In the standard configuration you have an excellent projection eyepiece for moon and the planets.

A Large Useful Field of View

The eye lens of the Hyperion eyepieces has been designed for largest possible useful field. Vignetting in digital cameras with fixed lens is drastically reduced
