PlaneWave CDK350 Telescope System f/7.2

Based on the technology of our PW-1000 (1-meter) Observatory telescope, PlaneWave combines its revolutionary optical systems with its brand new innovative L-Series direct drive mount that sets a new standard for small observatory telescopes.

PlaneWave CDK350 Telescope System f/7.2 consits of the CDK14 and the L-350 Direct Drive Mount with integrated high resolution encoders and high speed slewing.

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. More about the Optical Design (CDK).
