The extension of evolution of high-end telescope systems with 2.5m aperture.
ASA’s biggest mirror with 2,5m is built in the AZ2500 as a fully integrated Alt/Az observatory telescope system. This system is also equipped with quartz glass optics from ASA, which 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 reducing the size and cost of your dome infrastructure.
