The Baader Hyperion 36 mm (2") eyepiece has a field of view of 72° - exactly the distance your eyes can see without moving. The 8-member lens system, arranged in five groups, gives a sharp, colour-free image across the entire field of view, with a comfortable 20 mm eye relief. Its grain-like lens materials and anti-reflective coating adapted to their type provide outstanding light transmission and colour fidelity. It is ghost-free thanks to anti-reflective latches. On top of the eyepiece, there is an M43x0.75 thread for mounting various cameras.
The 21 mm eyepiece gives a similar field of view to a 32 mm Plössl, but the higher magnification makes the sky more spectacular.
Hyperion 31 mm and 36 mm eyepieces offer the maximum in a 2" eyepiece: although they have a 1.25" adapter, you can expect increased vignetting in this size of focuser.
