Eyepieces

As a visual eyepiece, we have found the Hyperions deliver superb sharpness and color fidelity across their 68° wide, flat-field, even in fast telescopes. In our own comparisons to our personal favorites, the Pentax XL, the Hyperions matched the Pentax in every regard, and at just over 1/3 the price! From their superb on-axis and off-axis sharpness, to their pitch-black high contrast field, the Hyperions really work. Viewing through a Hyperion is notably comfortable and relaxing, due to their forgiving eye-position, 20mm of eye-relief, and an optical design that is free of the annoying kidney-bean effect.
