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 FC-100D series consists of an apochromatic fluorite Steinheil doublet with a 100 mm objective diameter.  Two focal lengths are available:  a 740 mm f/7.4 instrument, and a 900 mm f/9.0 instrument.  The front element uses an eco-glass for maximum light transmission, with a coated fluorite rear element for superb color correction. 


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.


The FC-100DF is optically identical to the DC model, but features an enhanced 2.7–inch focuser.  It also features a shorter tube length that provides additional back focus for digital imaging applications.  This added back focus allows use of the FC-35RD reducer, which converts the DF to an f/5.4 instrument.


The FC-100DL is a full-fledged long focal length apochromatic refractor from Takahashi. This is the same FC-100DL that was offered in limited quantities in previous years. With the exception of the focal length, it is identical to the FC-100DF.

APRIL 2017 . . .

The FC-100DL was released as a limited edition several years ago by Takahashi.  Because of it’s popularity then, Takahashi has brought this telescope back for a second run.  The FC-100DL is a 100 mm aperture long focal length doublet similar to the FC-100DF, but with a 900 mm focal length.  It has the same heavy duty focuser with fine focus reduction and is able to use the same extenders and reducers as the FC-100DF.  Production limited to 100 scopes worldwide.
