PlaneWave CDK300 Telescope System

PlaneWave CDK300 – 0.32-Meter Observatory Telescope System

A precision-engineered observatory platform for serious imaging and scientific observation.

The PlaneWave CDK300 system brings together the CDK12.5 optical tube assembly and the high-performance L-350 Direct Drive Mount, forming a compact, yet powerful observatory solution tailored for dedicated astrophotographers and astronomy researchers. Derived from the cutting-edge technology behind PlaneWave’s PW-1000 1-meter observatory telescope, this system offers unmatched performance in a mid-sized format.

Employing the Corrected Dall-Kirkham optical design, the CDK12.5 delivers a perfectly flat, coma-free, and astigmatism-free image field out to 52mm—ideal for large-format imaging and precise celestial measurements.
