Product description

The Takahashi TSA-120 is equipped with an air-spaced ED triplet apochromatic lens with 120 mm diameter (900 mm focal length and F/D 7.5), mounted in a 3-element barrel. The latter ensures good stability of the optomechanical chain in the face of usual transport constraints and significant variations in operating temperature. It has a retractable dew shield and the length of the tube does not exceed 990 mm for a moderate weight of 6.7 kg.

The lens has been designed to achieve a very high level of performance in observation and photography. The chromatic aberration in short wavelengths (blue and violet) is reduced by one third compared to the old FS-102/FS-128 with Fluorite lens. The Strehl ratio at optimal wavelengths of human vision is almost perfect, at 99.2%, equivalent to that of the TOA series.

The TSA-120 is therefore a lightweight, compact and economical refractor, whose performance is similar to that of the TOA, Takahashi's flagship models and recognized as among the best in the world.
