ASA600 Ritchey-Chrétien f7 telescope

Next level telescope ready for more.

ASA600 OTA is the perfect fit for the ASA Direct Drive mounts with absolute encoders. As all ASA telescopes the ASA600 is equipped with quartz glass optics from ASA. Our optics guarantee diffraction limited performance and best micro roughness numbers even under the most perfect earthbound astronomical seeing conditions while maintaining a fast f-ratio primary mirror design leading to less obstruction, higher contrast and a more compact system.

f7/f2.5 full carbon Richey-Chrétien design with absolute encoder secondary mirror focusing unit.

This big 600mm telescope is also available as a package in combination with a ASA DDM200 Direct Drive mount and also as a package in combination with a ASA DDM100 Direct Drive mount!

RC & CDK Comparison

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.
