FC-76DCU TUBE ASSEMBLY COMPLETE D-76mm F-570mm F/7.5 (FLUORITE DOUBLET)


The Takahashi FC-76DCU apochromatic refractor is equipped with a fluorite doublet at F/7.5. Its very low weight, only 1.9 kg for the tube alone, makes it a very portable instrument, usable on a simple photo tripod. It comes with a fixed dew shield and a 31.75 mm compact rack-and-pinion focuser inherited from the FS-60CB. A brake locks the focus and it is possible to add an optional Camera Angle Adjuster (CAA) to make it easier to frame the picture.

The FC-76DCU can be equipped with a focal reducer (76D-RD) or with a field corrector (76D-FL or multi-flattener FC/FS MFL1.04X) for deep sky imaging.

The 80 mm diameter tube is in 2 parts. It can receive the Extender 1.7XR from the FS-60Q, which increases the F/D ratio from 7.5 to 12.75. The focal length gain then allows optimal chromatic correction for unforgettable planetary observations.

For FS-60CB owners, there is a conversion kit available to convert this refractor to FC-76DCU.
