Omegon Pro 1.25'', 45° penta-prism

Pentaprism: Effortless Orientation with a 90° Viewing Angle and Crystal-Clear Images

Experience seamless navigation through the cosmos with the Omegon Pentaprism, a quintessential accessory for refractors and catadioptric telescopes. Offering a natural 90° viewing angle, this five-sided prism ensures optimal comfort and eliminates physical strain during observation sessions. Whether you opt for the 90° or 45° viewing angle version, orienting yourself in the night sky becomes a breeze, especially when consulting lunar and star charts.

Key Advantages:

• Natural orientation at 90°: Enjoy telescope observations akin to a straight-through refractor, enhancing ease of use and comfort.
• Observer-friendly design: Simplify orientation with lunar and star maps, ensuring seamless navigation through celestial wonders.
• 29mm optical aperture: Accommodate long eyepiece focal lengths and wide fields of view without vignetting, delivering immersive stargazing experiences.
• 120mm optical path: Ensure precise image reproduction, surpassing the performance of traditional Amici prisms.
• Superior image quality: Crafted with BK-7 glass, dielectric mirrors, and multi-coated optical surfaces, the Pentaprism delivers unparalleled brightness and contrast. Its innovative design mitigates image degradation, resulting in stunningly clear views rivaling those of premium Amici prisms.
• Vignetting-free viewing: Enjoy unobstructed observation with no darkening at the edge of the field of view, enabling the use of long focal length eyepieces or wide fields of view.
• Anodized housing with low-reflection blackening: The prism's interior features light-tight construction, maintaining high contrast and ensuring an enjoyable observing experience.

Professional Aid for Astronomical Observing:

The Pentaprism revolutionizes astronomical orientation by providing an image orientation identical to that of a refractor. Equipped with two highly reflective reflecting surfaces, this optical marvel ensures incoming light always forms a right angle, regardless of the angle of incidence.
