The PlaneWave CDK500 combines a 20-inch Corrected Dall-Kirkham optical tube with the L-500 direct-drive mount, creating a premium system designed for serious astrophotographers and research applications. The CDK20 features fused silica optics and a dual carbon-fiber truss design that delivers a flat, coma-free field across a 52mm image circle with exceptional optical performance for large-format imaging. The L-500 mount employs direct-drive motors on each axis with high-resolution encoders, providing zero backlash, zero periodic error, and sidereal tracking accuracy of less than 0.30 arcseconds RMS, making it ideal for both visual observation and long-exposure astrophotography.
