ASA AZ1500 Ritchey-Chrétien Alt-Az telescope f6
|
An evolution milestone of high-end telescope systems with 1.5m aperture. This complete solution represents a fully integrated alt-az observatory system. The AZ1500 1.5m is equipped with quartz optics from ASA. This guarantees diffraction-limited performance and best micro-roughness values even under the most perfect Earth-based astronomical seeing conditions. With fast focal ratio, the design results in less obstruction, higher contrast, and a more compact system. The size and cost of your dome infrastructure is reduced. Main Facts
