Baader Hyperion Universal Mark IV 2", 8-24mm Zoom eyepiece (53114)

The Hyperion Zoom Eyepiece, now in its fourth generation, offers five focal lengths in one compact design: 8, 12, 16, 20, and 24 mm. With an improved click-stop detent mechanism and an apparent field of view ranging up to 68°, this eyepiece delivers exceptional versatility and performance. It is ideal for both visual observation and imaging, making it a favorite among amateur astronomers and professionals alike.

Some of the standout features of this high-quality zoom eyepiece include:

• Telescope Connection: Compatible with both 2" and 1.25" focusers, as well as bino-viewers. It also includes a 1 3/8" spotting scope thread for additional versatility.
• Camera Compatibility: Features an M43 camera/video adapter thread for afocal and classic projection photography, allowing easy connection to most cameras.
• Visual Use: Comes with three interchangeable eyecups—an adjustable height eyecup, a smaller rubber eyecup, and a fold-down winged eyecup—ensuring comfort for all users.
• Safety Design: Equipped with safety kerfs instead of grooves to prevent accidental slippage without causing irritation during use.
• Convenient Carrying: Includes an eyepiece holster with a belt loop that can also attach to tripod legs for easy transport and accessibility.

Baader Phantom Group Coating™

This eyepiece features Baader's advanced Phantom Group coating™, a 7-layer broadband anti-reflection coating designed to minimize residual reflections and maximize light transmission. Each glass surface is coated with a system optimized for the human eye's peak sensitivity at night (around 520 nm in the green spectrum). The coatings are nearly colorless, ensuring minimal light loss and no interference from scattered light.

Unlike lower-quality coatings that produce strong green reflections (indicating wasted light), Baader's Phantom Group coating ensures efficient light transmission across the visible spectrum, preserving image brightness and contrast in critical wavelengths.
