Vai al moduloThe new Baader Hyperion eyepieces set new standards in optical performance and versatility. The 21mm model features a 68° apparent field of view, perfectly matched to the human eye's physiology—offering a natural immersive experience without the need to shift your gaze.
Thanks to an advanced optical design with 8 elements in 5 groups, it delivers sharp definition across the entire field and excellent color fidelity, even at the edges.
Dual use: with the 2" adapter, it functions as a wide-angle eyepiece with low magnification. With the 1.25" negative element, it provides the designated magnification. Ideal for deep-sky observation and visual comfort.
