TOA-130NS

The Triplet Ortho-Apochromat concept of the TOA refractors makes it possible to combine sharpness and extraordinary contrast.
Description

The Triplet Ortho-Apochromat concept of the TOA refractors makes it possible to combine sharpness and extraordinary contrast. This unique optical formula, based on a highly air-spaced ED triplet, has the advantage of completely eliminating spherical aberration while having the best chromatic correction in the Takahashi telescopes range. TOA excels in both high planetary resolution and deep sky imaging, fully exploiting the capabilities of cameras with the largest sensors.

The NS version of the TOA-130 is equipped with a conventional 69 mm diameter rack-and-pinion focuser and a retractable dew shield. A balancing ring is provided to compensate for the weight of the lens cell. In photography, the mounting of the optional TOA-35 FL field corrector offers a consistent image circle of 40 mm. There is also a focal reducer (TOA-35 RD) with a coefficient of 0.7x.
