Baader Aspheric Hyperion 31mm 2 /50.8mm

31mm Aspheric 2" eyepiece with reducer to 1¼" plug-in diameter and incl. rubber eyecup / lens hood #2454653. The aspheric correction of an optical system eliminates numerous imaging errors. Sharpness is maintained over the entire field of view and distortion is reduced to a minimum. In addition, the eyepiece can be made much more compact and lighter. Excellent viewing behavior without "kidney bean" effect. Extremely light and small and can be used as a photographic plano projector with all Hyperion system connections. Optimized phantom multi-coating for maximum transmission and very good contrast. Adaptation to T2 for SLR cameras and to almost all filter threads of digital cameras. 1.25" adapter included. Focal length: 31mm, field of view: 72°, weight: approx. 400g Coating: multi-coating on each glass/air surface
