ASA 600 f7

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/!

Model until 2024

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.

Electronic: 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 remote controllable Software. /More/

Optic: Only the best for your telescope!We believe that the most important part in producing optics is the testing. So ASA decided that we invest in the best test equipment available, remove any measuring error as good as possible and use real values in our specifications. /More/

Technology: Our mounts are manufactured with the lastest CNC technology. /More/
