Takahashi

Takahashi telescopes, correctors, eyepieces and accessories at Ontario Telescope and Accessories. Takahashi builds fluorite and ED apochromatic refractors, Dall-Kirkham Cassegrains and hyperbolic astrographs in Tokyo, along with the matched flatteners, reducers, extenders and adapters that complete each system. Every optical train is documented by a published system chart, so the parts fit together with known spacing rather than trial and error.
