The Levenhuk Ra R80 ED optical tube with doublet is a two-lens apochromatic refractor with extra-low dispersion optics. This optical tube is perfect for astrophotography, especially of large objects, and is also suitable for direct observations. It features a wide field of view, high resolution, and excellent mechanics. Thanks to its compact size and lightweight, this optical tube proves indispensable during excursions. Additionally, the kit includes a sturdy aluminum case for protection and transport.
This telescope effectively reduces chromatic aberrations and delivers clear and high-contrast images. The fully multi-coated optics allow observing even the faintest stars. It is possible to observe both deep sky and cosmic space. Thanks to the dual-speed focuser, 2'' accessories can be installed. The focuser ensures extremely precise sharpness adjustment.
This OTA is made of anodized aluminum and features high-quality internal blackening. The quick-release knurled screw allows mounting this OTA on most modern mounts.
Please note: mount, tripod, and optical accessories are not included.
