Optical Tube Assemblies

This first addition to the new Epsilon Series introduces the newly designed ED corrector and fast speed of f/2.8. This fast field photo/visual astrograph is perfect for digital 35mm cameras and CCD cameras.

The Takahashi Epsilon-180ED (D=180mm, F/2.8), based on catadioptric telescope design (means association of lenses and mirrors) offers a fundamental innovation compared with Newton reflector or Schmidt astrograph.

Are you looking for an extreme high quality refractor telescope to serve across a variety of purposes? Then look no more... Takahashi has your answer with the FS-60CB Fluorite Refractor

Dall-Kirkham Telescope combines refractor-like performance in a larger folded optic reflector design. The Takahashi Mewlon 210 at prime focus provides a focal length of 2415mm, focal ratio of f/11.5 and image circle of 18mm

The Mewlon combines refractor-like performance in a larger folded optic reflector design. The 250 optical tube assembly has 9.8" of aperture and a focal ratio of 12.

The Mewlon combines refractor-like performance in a larger folded optic reflector design.The 300 optical tube assembly has 11.8" of aperture and a focal ratio of 11.9

The Takahashi Sky 90 is a refractor telescope that executes optical excellence.

The Takahashi TOA-150B optical tube assembly is based upon an apochromatic refractor design which is beneficial to inhibit uncessary color often exposed when viewing bright stars and/or planets.

The TSA-10S2 is the first in the new TSA line of Takahashi triplet apochromats. The color free images produced will delight the lunar, planetary and deep sky observer with very high contract images with pin point stars.

CCD cameras have challenged telescope optics beyond anything ever placed at the focal plane. I knew our APO objectives were up to the challenge, and with the proper tweaks would be extraordinary tools for the imager.

Both the optical and mechanical designs have been revised to reduce atmospheric defocusing sensitivity (visually the difference is virtually indiscernible)
