Founded in 2006, PlaneWave Instruments is committed to providing observatory-class products for serious astronomers at an unprecedented value. Developed by PlaneWave, the CDK (Corrected Dall-Kirkham) is a revolutionary new telescope optical system that was designed to excel at imaging on large format CCD cameras while remaining an excellent instrument for visual use. Created to meet the demands of both the serious imager and visual observer, the CDK 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 Ritchey-Chr├ętien (RC) telescopes as well as imaging and observatory class mounts to provide complete imaging systems for both individuals and industry.
