Levenhuk Ra R80 ED Doublet OTA is a two-lens apochromatic refractor with extra-low dispersion optics. This optical tube is perfect for astrophotography, especially for extended objects, and quite well for visual observations. It features a wide field of view, high resolution, and excellent mechanics. Due to its compact size and light weight, this optical tube is irreplaceable during trips. In addition, the kit includes robust aluminum case for storage and transportation.

The telescope effectively reduces chromatic aberration, transmits images of high contrast and clarity. Fully multi-coated optics allows for observing even faint stars. You can easily observe deep sky as well as outer space. Due to the dual-speed focuser, the 2’‘ accessories can be installed. The focuser provides a very precise sharpness adjustment.

The OTA is made of anodized aluminum and features a high-quality blackening inside. The quick-release thumbscrew allows for installing this OTA on most modern mounts.
