Levenhuk Ra R90 ED Doublet OTA is a compact refractor that has an objective lens of 90-mm (3.5-in) diameter and a focal length of 500 mm (19.7 in). The apochromatic objective lens consists of two 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.
This telescope tube is fitted with a dual-speed Crayford focuser that guarantees high precision focusing with no backlash. The 1.25'' barrel diameter of the focuser allows you to use a number of accessories with this telescope. Levenhuk Ra R90 ED Doublet OTA also comes with an aluminum case for you to store and transport your telescope.
