The CDK Optical Design

The CDK 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 of the unique features 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 a 52mm image circle.
This means pinpoint stars from the center out to the corner of the field of view.  More on the optical design.
