    Product Description
    Details
    Baader Aspheric 31mm 2" Eyepiece Baader Planetarium has evolved the wide-field astronomical eyepiece to a new level. Introducing the world’s first production Astronomical Eyepieces to use aspheric surfaces, the Baader Hyperion-Aspheric 31mm Telescope Eyepiece. This new technology has allowed Baader to eliminate eyepiece aberrations without the usual penalty of extra lens elements, excessive size and weight, or high cost. The Hyperion-Aspheric’s freedom from blackouts, kidney beaning, and lack of distortion combines with their long eye relief to produce a view that is uncommonly comfortable and natural for all users (including eye-glass wearers and users of popular astigmatism correcting lenses). The ultra-wide 72° field is extremely flat and distortionless (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. Superb for projection imaging. The Hyperion-Aspherics 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. Dual Barrel Configuration – two barrel sizes are provided with each Hyperion Aspheric. The standard 2” barrel provides the full 72º field size, and a special wide-field 1¼” barrel provides the maximum true field ever in a 1¼” format, with a field stop size of 1.265”(32mm)! - perfect for extracting every bit of field possible in 1¼” telescopes or binoviewers.
