Takahashi FS-128

The FS-128 and FS-128F are two versatile highly transportable 5" apochromatic refractors. With their multi-coated diffraction-limited optics, they produce the brightest possible images with outstanding contrast and color fidelity. Each has knife-edged baffles and the focuser painted inside with the same paint used on expensive 35mm cameras to eliminate internal light reflection. Their focal length of f/8.1 and f/5.9, with dedicated focal reducer, enable these instruments to be used as first rate wide field astrographs or lunar and planetary telescopes.

The FS-128 uses a 2.7" focuser and the FS-128F uses a 4" focuser. This is definite advantage for the serious astrophotographer. A 35mm, meduim format 6x7 vacuum holder, or 6x7 camera can be used to produce incredible astrophotos. The FS-128F opens new territory in astro-photography for 5" refractors. The dedicated reducer at f/5.9 produces a 63mm circle, while the dedicated flattener at f/9 produces an amazing 89mm circle on 6x7 film!
