Levenhuk Ra R130 ED Triplet OTA is a refractor with a 130-mm (5.1-in) objective lens capable of yielding sharp and clear views of celestial objects. 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 retractable dew cap on the front end of the telescope tube protects the optics from humidity when needed most. The telescope tube of this model is made of metal, following a more traditional design.

The telescope tube is fitted with a modern dual-speed Crayford focuser that provides for precision focusing and eliminates backlash. The 1.25'' barrel diameter of the focuser allows you to use a number of accessories with this telescope. Levenhuk Ra R130 ED Triplet OTA also comes with an aluminum case for you to store and transport your telescope.
