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.
1500mm f6/f2 Ritchey-Chrétien Nasmyth design is equipped with absolute encoder secondary mirror focusing unit and configurable with up to 4 Nasmyth ports.

RC & CDK Comparison
In our comparison, we compare our corrected RC to a CDK (corrected Dall-Kirkham):
1. The ASA RC primary mirrors are faster than a CDK and therefore the OTA is significantly shorter.
2. The CDK design requires a larger secondary for a given aperture (RC offers higher contrast).
3. ASA’s design is more versatile than the CDK where the corrective optics must be used.
Our closed loop direct drive systems, sensor technology and observatory safety modules play a major role in achieving optimum results. All moving accessory components are equipped with high-resolution encoders and closed-loop feedback systems. We provide event timer modules, and customer updatable firmware.
