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-130NFB is supplied with a retractable dew shield. The oversized 102 mm diameter rack-and-pinion focuser is equipped with a 1/7 ratio microfocuser and with a CAA (Camera Angle Adjuster) for photographic framing. Thanks to this configuration, the NFB is resolutely turned towards imaging. It allows more robust photo shooting, especially with large CCD cameras, without generating mechanical constraints. This focuser accepts some specific accessories, such as the 67 FL super-corrector which offers an incredible 92 mm image circle (60% unvignetted).
