PlaneWave CDK17 Optical Tube Assembly
Capturing the most stunning astrophotographs possible is something our team is passionate about. From design to manufacture, our goal with the Corrected Dall-Kirkham (CDK) 17″ telescope was centered around performance and ease of use. The CDK17 is an incredible breakthrough in telescope technology and produces no off-axis coma and no off-axis astigmatism. Additionally, the CDK17 provides a perfectly flat field so your astrophotographs will have stunning clarity from corner to corner of the image without field curvature degrading the photos. Offering the simplicity of single-mirror collimation, the stray light control of advanced baffles, structural performance created through finite element analysis (FEA), and decades of telescope design experience, the CDK17 is an exceptional diffraction-limited telescope. CDK17 users can experience pinpoint stars edge-to-edge and a 61 x 61 arcminute field of view when using large 16803 size camera sensors. When equipment fades into the background and simply performs, the astrophotography experience becomes even more fun and rewarding!
- f/6.8 and 2939mm focal length.
- No coma, no off-axis astigmatism, and no field curvature.
- Pinpoint stars across a 70mm image circle.
- Rock solid fused silica mirrors with low thermal expansion.
- Carbon fiber optical tube assembly for rigidity and fast cooling.
- Simple secondary mirror collimation thanks to the fixed primary mirror.
