The CDK20 is an innovative solution for unsurpassed astroimaging quality at an affordable price. The CDK telescope design provides excellent imaging with large format CCD cameras while remaining superb for visual use. The CDK design far exceeds the off-axis performance of most commercial telescope designs including the Ritchey-Chrétien design.

PlaneWave 20" CDK20 Corrected Dall-Kirkham Carbon Fiber Truss Telescope - Fused Silica

The CDK20 is an innovative solution for unsurpassed astroimaging quality at an affordable price. The CDK telescope design provides excellent imaging with large format CCD cameras while remaining superb for visual use. The CDK design far exceeds the off-axis performance of most commercial telescope designs including the Ritchey-Chrétien design.

This no-compromise design is unique in making the optical alignment forgiving and collimation very easy. This guarantees the user the best possible performance from the telescope. The end result at the image plane of the CDK design is no off-axis coma, no off-axis astigmatism, perfectly flat field (no off-axis defocus). The CDK design will give you pinpoint stars from the center to the corner of the field of view.

Carbon Fiber Truss Design

Open truss tube design with carbon fiber frame minimizes thermal expansion which causes focus shift with changes in temperature. Carbon fiber truss design also promotes quick thermal cooling and provides a rigid, lightweight structure.

3D Printed Baffles

Planewave uses digital 3D printing technology to produce lightweight baffle tubes. 3D printers add successive layers of material to construct a baffle system with precision positioned internal stray light baffles to minimize vignetting and maximize image contrast.

Dovetail Expansion Joint

Allows for the difference in thermal expansion between carbon fiber and aluminium. The expansion joint allows the aluminum dovetail to expand and contract without stressing the carbon fiber lower truss.

Delta-T Ready

For added dew prevention, the CDK20 is internally wired with polyimide film heater pads and temperature sensor, ready to be controlled with the Delta-T.
