The Baader-MicroGuide is the only micrometric crosshair guiding eyepiece in the market, still being produced with the original GenuineOrtho lens set! This means: perfect sharpness, no ghosting and freedom from distortion across the full field of view - just like the real Ortho-optics design that Carl Zeiss had introduced originally for measuring purposes. The 12.5mm focal length is the ideal combination in regard to high magnification, generous viewing comfort and ample pupil distance.
