Baader - 31mm Hyperion 72° Aspheric 2" Eyepiece

Baader Planetarium 31mm Hyperion Aspheric Telescope Eyepiece

Baader has evolved the wide field astronomical eyepiece to a new level with the introduction of the Hyperion Aspherics. The 31mm Baader Hyperion Aspheric 72º Modular Eyepiece is 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 

The Baader Hyperion-Aspherics 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 72º 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.
