PlaneWave Instruments is committed to providing observatory-class CDK and RC optics for serious astronomers at an unprecedented value. Created to meet the demands of both the serious imager and visual observer, the CDK (Corrected Dall-Kirkham) is offered at an unprecedented value for a telescope of this quality and aperture. One advantage of the CDK design is its ease of collimation and achievable centering tolerance for a telescope of its class. This assures the user will get the best possible performance out of the telescope. The end result is a telescope which is free from off-axis coma, off-axis astigmatism, and curvature of field, yielding a perfectly flat field all the way out to the edge of the largest CCD sensors available today. Today PlaneWave makes a full line of CDK and RC telescopes as well as imaging and observatory class mounts to provide complete imaging systems for both individuals and industry.
