TOA-130NFB REFRACTOR OTA
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 TOA-150B is equipped with an oversized 102 mm (4") rack-and-pinion focuser (with 1/7 microfocuser), a CAA (Camera Angle Adjuster) ring for photographic framing, an FQR-1 base for 7x50 finder scope and a retractable dew shield. It can be combined with the TOA-35 RD 0.7x field flattener but also the 67 FL super-corrector offering an incredible 92 mm image circle.
The TOA-150B is the flagship of the Takahashi refractors. It is resolutely turned towards imaging. It supports, without mechanical constraints, the heaviest photo setups including large sensor CCD cameras.
