Like the FS series, the FC series are apochromatic refractors with two-element fluorite lenses.  The FC series have larger apertures and longer focal lengths than the FS series, and provide outstanding performance both for the visual observer and the digital imager.  The FC series has its own dedicated set of reducers and flatteners, and is also able to use some of these accessories from the TOA series. The front element uses an eco-glass for maximum light transmission, with a coated fluorite rear element for superb color correction. The FC-76DCU model features a fixed dew shield and smaller, 80 mm diameter barrel for the same performance in a package featuring reduced weight and overall length.  It utilizes a 1.25 inch rack and pinion focuser.
