Baader 36 mm Hyperion Aspheric Eyepiece - 2"/1.25" - HYP-36

The Baader 36 mm Hyperion Aspheric 72 Degree Modular Eyepiece is one of the world's first eyepieces with aspheric surfaces! This technology has allowed Baader to eliminate eyepiece aberrations without the usual penalty of extra lens elements or excessive size and weight.

The Baader 36 mm Hyperion-Aspheric Eyepiece is great for projection imaging, and is threaded to accept the full line of Hyperion Digital T-Rings for a robust direct attachment of almost any camera. The clever use of 2"x24tpi SCT threads for attaching the 2" barrel permits the Hyperion-Aspheric to directly thread onto the rear cell of popular SCTs. This results in the highest rigidity possible for imaging. Two barrel sizes are provided with each Hyperion Aspheric. The standard 2" barrel provides the full 72 degree field of view, and a special wide field 1-1/4" barrel provides the maximum true field ever in this barrel size, with a field stop of 1.265 (32mm!) - perfect for extracting every bit of field possible in 1.25" focusers or binoviewers.  

• The Baader Hyperion Aspheric eyepiece offers freedom from blackouts, kidney beaning, and lack of distortion, and combines with long eye relief to produce a view that is uncommonly comfortable and natural for all users. Even eyeglass wearers and users of popular astigmatism correcting lenses will enjoy the comfort level of this 36 mm Baader Hyperion Aspheric!

    

• The ultra-wide 72 degree field of view of this eyepiece is extremely flat and without distortion, and is virtually free of angular magnification distortion.

   

• Baader's renowned Phantom Group Multi-Coatings and thorough internal baffling produce an extremely bright and high contrast view that is free of scatter.

   

• The Hyperion Aspheric eyepiece accept Tele Vue's Dioptrx astigmatism correcting lenses.

    

• Threads onto the back of most SCT rear cells, producing a rigid connection for imaging.
