FC-100D Refractor Telescope

Description 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. FC-100D The FC-100D series consists of an apochromatic fluorite Steinheil doublet with a 100 mm objective diameter. Both telescopes in the series are 740 mm f/7.4 instruments. The front element uses an eco-glass for maximum light transmission, with a coated fluorite rear element for superb color correction.  FC-100DC The FC-100DC model features a fixed dew shield and a 2.2 inch rack and pinion focuser.  While a capable imaging instrument, it is designed with the visual observer in mind. FC-100DF The FC-100DF is optically identical to the DC model, but features an enhanced 2.7
