Baader Hyperion eyepiece 8mm

Introducing the latest innovation from Baader: the Hyperion multifunctional wide-angle eyepieces, setting a new benchmark for optical excellence:

These eyepieces offer a 68° field of view, optimized for human vision, allowing for a complete view even with slight, involuntary head movements—ideal for prolonged observation sessions.

Engineered with eight lens elements in five groups, they provide unrivaled sharpness across the entire field and exhibit exceptional color fidelity right to the edges.

A versatile design enables dual functionality: the 2" barrel allows for wide-field, low magnification viewing without the negative achromat group, and a standard magnification is achieved with the inclusion of the 1.25" negative achromat group.

These eyepieces feature the lowest distortion and minimal astigmatism, thanks to the use of high refractive index glass elements. They also have the shortest field stop among all wide-field eyepieces currently available.

Designed specifically for binocular viewing, they ensure comfortable use with no 'kidney-bean effect', a common issue where the image disappears with slight movements—these eyepieces maintain a stable image throughout.

Additionally, they serve as effective projective lenses for photography. By replacing the eyecup with an M43-T2 adapter, they can connect to SLR and digital cameras, accommodating a wide range of devices through various adapter rings. Video cameras and webcams can also be attached, and the focal length can be adjusted by inserting spacers. Their design is compatible with bino-viewers, and the foldable eyecups provide ample eye relief for those who wear glasses.

Key Advantages:

• Superior craftsmanship ensuring durability and precision.
• Relaxed and immersive viewing with a large, clear field of view.
• Sharp imaging with excellent color fidelity across the entire field.
• Dual barrel functionality for varied observational flexibility.
• Minimized distortion and astigmatism for clear, accurate visuals.
• Absence of the 'kidney bean' effect, enhancing user comfort.
• Baader Phantom Group coating™: This advanced 7-layer broadband anti-reflection coating minimizes residual reflections. Each type of glass is specifically treated to maximize its effectiveness at about 520nm—the wavelength where the human eye is most sensitive in low light conditions.

These coatings are almost colorless, ensuring that they are effective across the visible spectrum and preventing any loss of light to the night-adapted eye while eliminating scattered light interference.

If you observe a strong green reflection on a lens surface, it is not from the Baader Phantom Group coating—such reflections indicate older, less efficient technologies that reflect light in the critical spectral range of 500-550nm, leading to light loss.
