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.
