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 –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.

FC-100DL 

 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. It also includes the MEF-3 focuser.

Optical Tube Assembly only (mount, tripod, tube holder and finder sold separately).
