ASA AZ1200 Ritchey-Chrétien Alt-Az telescope f7 f2
|
Next level high-end telescope system with 1.2m aperture. This complete solution represents a fully integrated alt-az observatory system. The AZ1200 1.2m 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
