Takahashi FC-76DS O.T.A.



The new FS-78D is an updated version of the original FC-76 from 1980. 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 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 reducer 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.

Both models are allow the user to use either for solar eclipse

imaging. Both can be carried by the Teegul Sky Patrol III

or larger PM-1.
