Baader Hyperion 5mm 1.25" & 2" Eyepiece

The Baader Hyperion 5mm Eyepiece is engineered for observers who want crisp, high-magnification views without sacrificing comfort or image quality. Designed for detailed lunar, planetary, and double-star observation, this eyepiece is ideal for nights of steady seeing when fine detail truly matters.

High-Power Performance with a Wide Field

With a generous 68-degree apparent field of view, the Hyperion 5mm delivers a noticeably wider and more immersive image than traditional high-power eyepieces. This wider field helps keep objects in view longer, making it particularly useful for manual mounts and Dobsonian telescopes.

High-Contrast Optics with Phantom Group Coatings

Baader’s use of high-index optical glass combined with advanced Phantom Group multi-coatings ensures excellent contrast, sharpness, and light transmission. Internal reflections are kept to a minimum, resulting in darker backgrounds and well-defined planetary detail. Subtle surface features on the Moon and fine structure in planetary atmospheres are rendered with impressive clarity.

Comfortable Viewing at High Magnification

Despite its short focal length, the eyepiece maintains a comfortable 20mm eye relief, making it suitable for extended observing sessions and friendly for eyeglass wearers. The ergonomically designed housing further supports relaxed viewing, even during long periods at high magnification.

Flexible Dual 1.25" & 2" Compatibility

Built around Baader’s modular Hyperion system, the 5mm eyepiece is compatible with both 1.25-inch and 2-inch focusers via interchangeable barrels. This modular design offers excellent flexibility across a wide range of telescope setups and allows the eyepiece to adapt easily as your equipment evolves.

The Baader Hyperion 5mm 1.25" & 2" Eyepiece is an excellent choice for astronomers seeking precision optics, comfortable high-power viewing, and long-term versatility in a premium eyepiece.
