The evolution milestone of telescopes.
The ASA800 0.8m is the largest aperture OTA offered from ASA without mount. Perfect fit for the ASA direct drive mounts with absolute encoders. As all ASA telescopes the ASA800 is equipped with quartz glass optics from ASA Our optics guarantee diffraction limited performance and best micro roughness numbers even under the most perfect earthbound astronomical seeing conditions while maintaining a fast f-ratio primary mirror design leading to less obstruction, higher contrast and a more compact system.
