The Baader Planetarium 17 mm Hyperion 68-degree Eyepiece offers world-class performance and unique photo-visual features. No longer do amateurs need to spend more on their eyepieces than their primary instrument in order to get true high-end performance in a wide-field eyepiece. Not just a different branded version of their highly regarded cousins, the Hyperion have been totally redesigned to deliver better transmission, contrast and useful new features.
Baader Planetarium has worked hard to give the Hyperion the world's finest optical coatings, superb mechanics and their unique multifunctional design. As a visual eyepiece, the Hyperion delivers superb sharpness and color fidelity across their 68-degree wide, flat-field even in fast telescopes. In comparison to the Pentax XL eyepieces, the Hyperion matched the Pentax in every regard.
From their superb on-axis and off-axis sharpness to their pitch-black high contrast field, the Hyperion really works. Viewing through a Hyperion is notably comfortable and relaxing due to their forgiving eye-position, 20 mm of eye-relief, extra-large eye lens and an optical design that is free of annoying 'kidney-beaning' and blackouts.
