Takahashi FC-100DF f/7.4 Doublet Fluorite Apochromat Refractor

Essentially a Takahashi FC-D100DC fitted with a larger, stronger, Sky 90 2.7" focuser making it more suitable for deep sky imaging with the optional FC35 Focal Reducer (provides a 44mm circle and an F4.9 focal ratio).

The new Takahashi FC-100DF is fitted with a premium quality F7.4 Fluorite doublet optic that provides superb contrast, sharpness and colour correction. 

Utilises  the Steinheil design with a fluorite rear element and an eco-glass front element. 

A versatile telescope that provides wonderful views at low and high magnifications but can also be used for astrophotography. When combined with the optional FC-76 Reducer the FC-100D operates at F5.4 and delivers a fully corrected 35mm circle that is perfect for APS sized DSLR's. 

The FC-100D is surprisingly light but. like all Takahashi scopes, is very well engineered.

The package version includes Tube Holder, 6x30 Finderscope and Bracket.
