About Baader Hyperion Aspheric Eyepieces...
Baader has evolved the wide field visual observing to a new level with the introduction of the Hyperion Aspheric Eyepiece. The Baader Hyperion Aspheric 72 Degree Modular Eyepieces are one of the world's first to incorporate aspheric surfaces! This new technology has allowed Baader to eliminate eyepiece aberrations without the usual penalty of extra lens elements, excessive size and weight, or higher.
Available in 31mm or 36mm focal lengths, the Baader Hyperion-Aspheric Eyepieces are great for projection imaging, and are 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-Aspherics 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.
