TAKAHASHI FC-100D - Imaging Use
Takahshi has just introduced an updated version of the original FC-100 now called the FC-100D. It has been designed for the digital age. The FC-100D uses the Steinheil design with the fluorite element in the rear and an eco-glass front element. The focal ratio has been reduced to f/7.4 with a 740mm fl.
The FC-100D was designed with a goal of being light weight and highly portable. It is offered in two light weight models: the ultra-portable DC visual model that weighs just 2.8kg [6.1lbs] uses the 2.2”FS-60CB focuser. While the DF model uses the 2.7” focuser and is designed to be used for imaging as well as visual using the dedicated four element FC-35 .66x new reducer that changes the focal ratio to f/4.9 with a Ø 44mm circle at a focal length of 485mm.
