    Takahashi FC-35 .66X Reducer
    for FC-125, FS-125 & FS-152 Telescopes

    The FC-35 0.66 X Reducer was designed by Takahashi Japan for a wide variety of their FC and FS series telescopes. This FC-35 comes with a dedicated CA 130 Ring, and is compatible with the FC-125, FS-128, and the FS-152 refractors. A FC-35 with CA 100 Ring is also available for the FC-100DF, FC-100 & FS-102. The only difference is this model comes with a CA 100 Ring instead of the CA 130.

    The FC-35 will reduce the focal length of your telescope by 10%, and will provide a 44 mm diameter image circle. The metal back, as measured from the flat, rear-most shoulder of the FC-35, is 70.3 mm. With the FC-35 & CA 130 Ring installed, each compatible telescope will have the following focal length and f/ratio:

    • FC-125: 672 mm, f/5.4
    • FS-128: 700 mm, f/5.5
    • FS-152: 819 mm, f/5.4
