PLANEWAVE REDUCER 0.66X FOR CDK12.5 / 14 / 17

This is a reducer designed specifically for PlaneWave CDK flat field telescopes. This reduces the f ratio of the CDK telescope 66%. The CDK12.5 f/8 telescope will be reduced down to f/5.3. The CDK14 will be f/4.8 and for CDK17 f/6.8 will be reduced to f/4.5

Note: 125166 adapter is compatible with CDK17 that have 10.24″ back focus. CDK17 with 8.81″ back focus will use the 200166 focal reducer.

We do not have vignetting plots for the reducer paired with the CDK 14", but from our estimation based on user data, there will be about 25% light falloff at the corners of a full-frame sensor. This can be easily corrected with flat frames. See the image below:
