PlaneWave manufactures your telescope of choice for unsurpassed astroimaging, research, or satellite tracking. Here are the basics of the PlaneWave CDK14:
- f/7.2 and 2563mm focal length.
- No coma, no off-axis astigmatism, and no field curvature.
- Pinpoint stars across a 70mm image circle.
- Rock solid fused silica mirrors with low thermal expansion.
- Carbon fiber optical tube assembly for rigidity and fast cooling.
- Simple secondary mirror collimation thanks to the fixed primary mirror.
NOTE: Shipping cost will be determined after the order is made and must be paid before the telescope will ship. A shipping quote can be obtained on request.

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. |
