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.
Technical Details
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.
