PlaneWave 14" CDK Corrected Dall-Kirkham Carbon Fiber Telescope
The PlaneWave Instruments CDK14 is a 14 inch (0.36 m) f/7.2 Corrected Dall-Kirkham Astrograph telescope. The CDK14 covers a 70 mm field of view without any field curvature, off-axis coma, or astigmatism. The CDK14 is a lightweight carbon-fiber truss design weighing less than 50lbs, with 3 cooling fans blowing air throughout the back of the telescope. The CDK optical design is the innovative solution for unsurpassed astro-imaging quality at an affordable price.
The CDK (Corrected Dall-Kirkham) Optical Design 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.
