The PlaneWave Instruments CDK14 is a 14 inch (0.36 m) f/7.2 Corrected Dall-Kirkham Astrograph telescope. The CDK14 covers a 70mm 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

STANDARD FEATURES
| CDK Optics | The Corrected Dall-Kirkham design yields a perfectly flat field free from off-axis astigmatism, coma and defocus. |
| Carbon Fiber Truss Design | Minimizes thermal expansion which causes focus shift with changes in temperature |
| Dovetail Expansion Joint | Allows for the difference in thermal expansion between carbon fiber and aluminum. The expansion joint allows the aluminum dovetail expand and contract without stressing the carbon fiber lower truss |
| Cooling Fans | Three cooling fans blow air inside the back of the telescope. This helps the telescope to reach thermal equilibrium quickly. The fans are controlled by a computer if the optional Electronic Focus Accessory (EFA Kit) is purchased. |
| Delta-T Ready | For added dew prevention, the CDK14 is internally wired with polyimide film heater pads and temperature sensor, ready to be controlled with the optional Delta-T controller. |
