Aspherical surfaces of the Baader Hyperion 31 mm eliminate distortions without introducing additional elements that would affect the weight of the eyepiece and its price. The eyepiece is compatible with the 2 "and 1.25" hood (reduction included). In addition, the Hyperion 31 mm eyepiece provides a wide 72 ° field of view and a comfortable distance from the eye.
Usually, rays of light passing through the lens near its edges are more refracted than rays near its axis. Therefore, the image in the uncorrected optical system may be blurred at the edge of the field of view.
Aspherical correction of the optical system eliminates several types of aberrations at once. We achieve sharpness in the whole field of view, while image distortions are reduced to a minimum, and the eyepiece can be much smaller and lighter.
