After the successful introduction of the CDK 12.5" and 17" Astrograph from PlaneWave for few years ago, the CDK 14" is now available in an aperture of 14"- which is much easier to finance than a CDK 17".
The abbreviation CDK stands for the optical system of the PlaneWave astrographs - a Dall Kirkham Cassegrain with a optical correction unit. The result is a CDK 14" which is free from off-axis coma and off-axis astigmatism, yielding a perfectly flat field all the way out to the edge of a 70mm image circle.
