Takahashi FC-76DS Doublet Fluorite Apochromatic Telescope


Takahashi FC-76DS Apochromatic Refractor Telescope
The new FS-78D is an updated version of the original FC-76 from 1980 by Takahashi. The multi-coated fluorite rear lens and eco-glass front element provides maximum light transmission. The design takes advantage of the advances in high resolution digital imaging. The advanced design allowed the focal length to be reduced by 30mm 594mm at f/7.8.

The FC-76DS by Takahashi features a 3.6” focuser for imaging with CCD cameras and DSLRs. A sliding dew shield is also included and a larger OD90mm tube.

The Takahashi FC-76DS model features a the Sky-90 2.6” focuser to better hold imaging packages which include DSLR’s and CCD cameras with filter wheels. A dedicated and flattener as well as extender are available to further enhance the capabilities of the FC-76DS.

The dedicated reducer changes the focal length to 417mm with a focal ratio of f/5.5 and an image circle of  36mm. While the dedicated flattener at f/7.8 and 594mm produces a 40mm flat circle.
