Levenhuk Ra R102 ED Triplet OTA is a refractor with a 102-mm (4-in) objective lens and focal ratio of f/7, best suited for visual observations of celestial objects. The telescope tube is fitted with a modern dual-speed Crayford focuser with the 3'' large diameter thread that provides for precision focusing and eliminates backlash.
The apochromatic objective lens consists of three lenses that reduce chromatic aberration to a barely noticeable minimum. The fully multi-coated lenses are made of ED glass and yield crisp and clear views of the night sky. The telescope tube of this model is made of metal, following a more traditional design.
