PLANEWAVE REDUCER 0.7X FOR CDK700

This reducer lens is designed specifically for flat field telescopes like the PlaneWave CDK700. This reduces the f ratio of the CDK700 telescope 70% yielding an effective focal length of 3150mm and an f-ratio of F/4.5 .

The reducer lens attaches to the Nasmyth focus port of the CDK700 and has mounting holes for attaching the IRF90 rotating focuser. The reducer lens has 3 inches of back focus from the mounting surface of the IRF90. 

Note: The use of the IRF90 with the reducer lens requires replacement of the threaded internal baffle (ROF 307).  Baffle come with standard with reducer lens.
