The FC-35 0.66x reducer was designed to be used with the FC-100DF to produce a 485mm focal length at f/4.9 which is a 34% reduction in the focal length. It produces a field flat to within 20 microns over a 35mm full frame.
This reducer is compatible with the following FC and FS Series telescopes: FC-100, FS-102, FC-125, FS-128 and FS-152. The FC-35 produces a 10% reduction in the focal length and a 1/3rd improvement to the RMS-Spot when compared to previous models.
The FC-35 has been designed for the digital imaging age. It is now available for most of Takahashi’s FC and FS refractors. All reducers are supplied with a dedicated CA ring.
