Baader 36mm Hyperion Aspheric 2" Eyepiece

Normally, near-the-edge, rays are refracted towards the center when passing a lens, as near-axis light beams. Therefore, the image field in an uncorrected system can become blurred to the edge. The aspherical correction of an optical system, as with these eyepieces, now resolves numerous imaging errors at once. The sharpness is achieved over the entire image field, the distortion is reduced to a minimum and the eyepiece can be made much smaller and lighter.

The eyepieces are each delivered with 1¼ "and 2" plug-in sleeves
