The PlaneWave CDK400 is a professional-grade 17-inch Corrected Dall-Kirkham astrograph telescope system designed for deep-sky imaging and astronomical research. This complete observatory package combines the CDK17 optical tube with PlaneWave's L-500 direct-drive mount, delivering exceptional off-axis optical performance with zero coma, astigmatism, and field curvature across a flat 70mm field of view. The system features fused silica mirrors, a carbon-fiber truss design with integrated cooling fans, and the L-500 mount's precision direct-drive motors with high-resolution encoders, enabling sub-0.30 arcsecond tracking accuracy and rapid 50 degree-per-second slew speeds for both astrophotography and visual observation.
