TAKAHASHI TOA-150B OPEN BOX SPECIAL
This is an Open Box Special of an unused TOA-150B. A customer bought this scope thinking it came with a mount and tripod, and then returned it within 24 hours of receipt for another system. This telescope has never been used and was shipped via 2nd day air both ways. It comes with the full Takahashi warranty and has been full inspected by Takahashi America technicians. The only reason it is not being sold as new is that it was shipped to a customer and then returned. Please call with any questions.
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 436 nm up to 656 nm is less than +/- 0.01 mm. This is less than 1/100 the aberration of a typical apochromatic design.
The TOA-150B is a 150 mm apochromatic f/7.3 refractor with a focal length of 1100 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.
A tube weight is standard to assist in balancing instrumentation or visual accessories.
Optical tube only. Mount, Accessories and Tripod sold separately.
