Optical tube Takahashi TOA-130NS (OTA) single tube with adapter to 50.8

The Triplet Ortho-Apochromat concept of TOA binoculars combines outstanding sharpness and contrast. This unique optical formula, based on a high air-gap ED triplet, has the advantage of completely eliminating spherical aberration, while offering the best chromatic correction in the binocular range Takahashi. The TOA excels in both high planetary resolution and deep sky imaging, taking full advantage of the capabilities of cameras with the largest sensors.

The NS version of the TOA-130 is equipped with a classic 69 mm diameter rack and retractable demister. A balance collar is included to counteract the weight of the lens. In photography, the optional TOA-35 FL corrector mount offers a substantial 40 mm image circle. There is also a focal length reducer (TOA-35 RD) with a coefficient of 0.7x.
