Takahashi Seisakusho of Tokyo, Japan has been producing fluorite apochromatic refracting telescopes since they introduced the 90mm f/10 FC-90 in 1979. This revolutionized amateur astronomy as the world's first fluorite apochromatic telescope in regular production. Since that time Takahashi has not only produced fluorite apochromats up to 250mm but also mountings and a variety of state-of-the-art telescopes such as the four-element FSQ-106, Hyperbolic Astrographs, Newtonian-Cassegrains and Dall-Kirkham Cassegrains.

Takahashi produces polar equatorial mounts from the ultra-compact Teegul Sky Patrol 2 to the 350lb. capacity, 2.5 arc-second accurate EM-3500 observatory mount. Additionally, Takahashi manufactures two small, compact alt-azimuth mountings with fine slow-motion controls for those who prefer the simplicity of this design for terrestrial and astronomical applications. All Takahashi metal castings are sand cast from their own factory located near their Urii, Japan fabrication facility.
