The Baader Classic Ortho series is a modern interpretation of a classic design, beloved by observers seeking unmatched sharpness and contrast. These orthoscopic eyepieces are specially developed for applications where detail reproduction is crucial – such as observing the Moon, planets, and double stars.
The eyepieces are available in 6 mm, 10 mm, and 18 mm focal lengths, each with a sharp 52° field of view. Thanks to their minimalist design (four lens groups), they deliver an exceptionally bright, high-contrast image with minimal internal reflections or chromatic aberration.
Unlike many modern wide-angle eyepieces, the Baader Classic Orthos are built with a sharply corrected image across the entire field. This makes them not only perfect for visual observations but also highly suitable for use in binoviewers, where compact construction and minimal distortion are essential.
Key Features:
- Orthoscopic design: superior sharpness and contrast for lunar and planetary observations
- 52° apparent field of view: wider than classic orthoscopics, without optical compromises
- Very low distortion: ideal for double stars and detail-rich observations
- Multicoated optics: minimal reflections and excellent light transmission
- Rubber eyecup included: comfortable use, even with glasses
- Perfect in binoviewers: low mass, excellent matching between eyepieces
