Baader Hyperion 10 mm 68° Modular Eyepiece

Baader Hyperion 10 mm 68° Modular Eyepiece

DESCRIPTION

The Baader Hyperion 10 mm 68° eyepiece is a versatile optical tool combining high contrast, precision, and modularity. With a 68° apparent field and 22 mm eye relief, it's ideal for lunar, planetary, and deep-sky observation at high magnification. The 8-element, 5-group optical layout delivers edge-to-edge sharpness.

Baader’s Phantom Group-Coating, applied to every optical surface, minimizes stray light and maximizes light transmission, especially around 520 nm – where night-adapted vision is most sensitive. The coating is nearly colorless, ensuring the most natural view possible.

This eyepiece includes 1¼" and 2" interchangeable barrels, both threaded for filters. It features two camera-adaptable threads (M43 and SP54) for direct afocal or classical projection. Focal length can be modified using Baader’s 14 mm and 28 mm fine tuning rings, without adding optical elements.

It can also be used with Zeiss Diascope spotting scopes via the Baader bayonet adapter (not included). An optional stop ring (#2958097) helps maintain perfect focus when switching eyepieces in 2" setups.
