Levenhuk Ra R115 ED Triplet OTA is a refractor with an objective lens of 115-mm (4.5-in) diameter that is perfect for visual observations of the celestial sphere. 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.
