  • The CDK14 is PlaneWave's 14" Corrected Dall-Kirkham Astrograph telescope.
  • Extra large, fast optics with a focal ratio of f/7.2.
  • Covers 70mm field of view without any field curvature, coma or astigmatism.
  • Ultra light-weight carbon fiber truss tube design makes this large telescope highly portable.
  • Cooling fans keep your optics temperature stable.


By pairing the classic Dall Kirkham design of an elliptical primary mirror combined with a spherical secondary mirror, with a correcting lens group PlaneWave creates an optimal imaging instrument. With an impressive image circle of 70mm that is completely flat and free from any coma or astigmatism, you'll be able to capture extremely wide field images. Focus is extremely stable and images are tack sharp.

Taking advantage of the natural durable, lightweight, temperature stable properties of carbon fiber, Planewave's CDK telescopes are not just portable but also resist focus shift which is extremely important during very long exposures. An open truss design helps to keep weight low - resulting in a 48 pound, 14" optical tube. Three cooling fans, located behind the primary mirror further help with keeping your mirror stable by ejecting air from the back of the telescope. Thermal equilibrium is quickly reached.

Add the optional EFA kit to control your fans via computer and don't forget the optional Delta T controller. Your PlaneWave Corrected Dall Kirkham telescope is already internally wired with polymide film heater pads and a temperature sensor to prevent dew.

Product Questions

How much better is the Planewave 14 inch than the Telestron 14 inch with there being a $5,000 difference. The Observatory in Dallas does not sell anything larger. Thanks
I live just north of a light polluted city. I have a 130 mm apo refractor in a observatory. I'd like a little more aperture. Would I be better with a TEC 180 FL or would the planewave 14" suffer more from light pollution. . I enjoy both visual and CCD..thanks
