    About the Takahashi FC-76DS Doublet Fluorite Refractor

    The FC-76DS model features a the Sky-90 2.6 focuser to better hold imaging packages which include DSLRs and CCD cameras with filter wheels. An optional dedicated flattener as well as extender are available to further enhance the capabilities of the FC-76DS. A sliding dew shield is also included and a larger OD 90 mm tube is standard.

    The optional dedicated reducer changes the focal length to 417 mm with a focal ratio of f/5.5 and an image circle of 36 mm. The dedicated flattener operates at f/7.8 and 594 mm produces a 40 mm flat circle. This telescope is exceptionally well-suited for solar eclipse imaging and can be carried by the Teegul Sky Patrol III or larger PM-1mount. When picking out accessories for any Takahashi telescope, a system chart is of great use.
