Takahashi designed the reducer TOA-35 high performance for TOA-130, TOA-150, TSA-102 TSA-120 and with a reduction ratio of 0.7x. The focal length is reduced by a factor of 30% thanks to 4 divided into three groups optical elements made of low-dispersion glass with a high refractive index. The result of applying this optical system Takahashi is a flat image, limpid and from the correct color. < / p>
The reducer TOA-35 is available with two optional adapters: the CA 130 (TK-TKA31202) is designed to work with the TOA-130, the CA 150 (TK-TKA32202) is designed to work with TOA-150, the TSA-120 TSA-102. p>
When used with a TOA-130/150, the focal reducer produces stars from 3 microns to 6 microns from the center and stars at the edges . When used with optical tubes Series TSA image is 8 microns and 12 microns at the center to the edge. p>
