Free Eyepiece Case


Receive a free eyepiece case when you buy this eyepiece from High Point Scientific! You will love the way the two piece “bolt-style” case threads together to securely protect your new eyepiece from dust, moisture, and scratches during storage.



Baader 31 mm Hyperion Aspheric 1.25" / 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 31 mm and 36 mm Baader Hyperion-Aspheric 72 degree Modular Eyepieces. 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" x 24 threads per inch (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 your imaging.




Compatible with and fits either 1.25" or 2" eyepiece barrels.
