10000053: Levenhuk Ra R66 ED Doublet Carbon OTA

Apochromatic refractor. Objective lens diameter: 66 mm. Focal length: 400 mm

Levenhuk Ra R66 ED Doublet Carbon OTA is a compact refractor for visual observations. It has a 66-mm (2.6-in) objective lens and a focal length of 400 mm (15.7 in). Its carbon fiber shell provides for extremely light weight, and significantly reduces the time it takes your telescope to adapt to outside temperatures. With the standard barrel diameter of 1.25'', this telescope readily accepts a number of various eyepieces - including those from different manufacturers. Levenhuk Ra R66 ED Doublet Carbon OTA also comes with an aluminum case for you to store and transport your telescope.

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 1.25'' barrel diameter of the focuser allows you to use a number of accessories with this telescope.
