- Great for visual and astrophotography
- Optional accessories for planetary and deep space imaging
- Larger 100mm aperture great high contrast views
- Excellent for viewing galaxies, globular clusters, nebulae, and planets
- Rear Flourite element for optimum color correction
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
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.
*Optical Tube Assembly only (mount, tripod, tube holder and finder sold separately).
