Takahashi FC-100DC Refractor Optical Tube

12/26/2024 update

Due to overwhelming demand, Takahashi just quoted delivery of March 2025 on this particular model.  We will consider any sale of this scope as of this date a special order.  This means it is non-refundable and you will own this telescope.  This isn't a normal way for us to conduct business, but we don't want to create a false economy for Takahashi or get stuck with tens of thousands of dollars of it as well.

The Takahashi FC-100D is Takahashi's latest update to the 100mm fluorite refractor.  The FC-100D uses the Steinheil design with the fluorite element in the rear and an eco-glass front element.  This apochromatic telescope provides outstanding views, both visually and with digital imaging hardware.

The FC-100D was designed to be light weight and highly portable. It is offered in two models: the ultra-portable DC visual model that weighs just 2.8kg [6.1lbs] and uses the 2.2" FS-60CB focuser, and the DF model that uses the 2.7" focuser and is designed for imaging as well as visual use.  In their standard configuration, each scope is a 740 mm f/7.4 doublet.

With the optional 4 element FC-35 reducer, the DF version becomes a 485 mm f/4.9 imaging telescope, providing a 44 mm imaging circle that is suitable for full frame CCD and DSLR cameras.
