1.25-inch / 2-inch 68 degree Apparent Field of View ocular with excellent image sharpness
A comfortable view - easily visible even with eyeglasses. A field of view of 68 degrees has been tested as being ideal for astronomical observations. It is the largest field of view that can be viewed without strain and turning your eyes. Excellent Image Sharpness both on axis and over the entire visible field these eyepieces offer an excellent image sharpness. Even short focal ratio Newtonians at an extreme f/4.5 offer good, sharp stars over the entire field.
The new 24mm uses a different optical design and delivers outstanding performance over its 68° wide apparent field. It is totally free of blackouts and other annoying exit pupil behaviors, delivers long eye relief (17mm), virtually zero distortion, and is sharp to the edge even in fast telescopes. Its flat focal plane is particularly suited to very fast newtonians that use coma correctors. The 29mm field stop makes the 24mm Hyperion the widest 24mm eyepiece we know of. The 24mm Hyperion is also the smallest and lightest of the Hyperions.
Very good light throughput and contrast, Hyperion eyepieces have an excellent multi-layer coating on each glass-to-air surface. Blackened lens edges and a blackened interior of the eyepiece body further reduce internal reflections and ghost images.
1.25" and 2" Dual Barrel Hyperion eyepieces do not only have a 1.25" barrel. The lower part of the eyepiece body is built as an additional 2" barrel similar to the superb Vixen LVW ep's.
