The new FC-76 Takahashi series is an updated version of the original 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. It allows the focal length to be reduced by 30mm 594mm at f/7.8. The model DC uses identical optical components in a smaller and lighter tube with a fixed lens shade and weighs a little less than 4lbs. The DC is easily transported and easy to set up.

Featuring a 2.6” focuser for imaging with CCD cameras and DSLRs makes it ideal for imaging. A fixed dew shield is included and a smaller, lighter 80mm tube is standard. The FC-76DC 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-76DC.

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