Description

The TOA series is a member of Takahashi’s line of triplet refractors.  In the TOA design, three lens elements are used, with the front and rear constructed from ED glass. The resulting system achieves a high level of apochromatic performance for both visual observation and imaging. Takahashi engineers have a undertaken a complete redesign of the triplet system, completely eliminating spherical aberration while minimizing axial chromatic aberration in the visible light spectrum.

In typical apochromatic designs, the elimination of chromatic aberration is usually at the expense of increasing spherical aberration at various wavelengths.  However, with the TOA series, the focal shift across the entire visible spectrum from 436nm up to 656nm is less than +/- 0.01mm. This is less than 1/100 the aberration of a typical apochromatic design.

TOA-130NS

The TOA-130NS is a 130mm apochromatic f/7.7 refractor with a focal length of 1000mm.  It features a retractable lens hood and 2.7inch rack and pinion focuser.  A complete line of flatteners, reducers and extenders are available, including the 67-series flattener, which provides a 90mm imaging circle.

TOA-130NFB

The TOA-130NFB is a 130mm apochromatic f/7.7 refractor with a focal length of 1000 mm.  It features a retractable lens hood, a 4 inch rack and pinion focuser with a 7:1 fine focuser, and a 360-degree camera angle adjuster.  A complete line of flatteners, reducers and extenders are available, including the 67-series flattener, which provides a 90 mm imaging circle. 

Optical Tube Assembly only (mount, tripod, tube holder and finder sold separately).
