ASA AZ1750 f6 f2

An evolution milestone of high-end telescope systems with 1.75m aperture.

This telescope system is a fully integrated Alt-Az observatory telescope system. The ASA AZ1750 1.75m is 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.
1750mm f2/f6 Ritchey-Chrétien Nasmyth design with absolute encoder secondary mirror focusing unit, and configurable with up to 4 Nasmyth ports.
