Baader Classic Ortho are parfocal eyepieces with very high transmission, very high contrast and thus an extremely clear, completely distortion-free image. Due to the multicoating optical treatment, they have extremely low internal reflections. The eyepieces offer 52° field of view, a very sharp field and excellent ergonomics for a comfortable viewing experience.
The Classic Ortho eyepieces optical design has four lenses. All the lenses are blackened to effectively suppress the effect of stray light. The anodized nose has an internal thread for receiving filters. The view is so great, with a very high resolution that the performances are close to 5 times more expensive pure planetary eyepieces. The same type of glass and the same optical design are used for the former Zeiss Jena orthoscopic eyepieces.
