Takahashi FC-100DC F/7.4 Fluorite Refractor OTA

Takahshi introduces an updated version of the original FC-100 designed for lightweight portability in mind. Weighing just 6.2 pounds, the Takahashi FC-100DC is a perfect travel companion. The FC-100D uses the Steinheil design with the fluorite rear element and an eco-glass front element. The focal ratio of f/7.4 can be reduced to f/4.9 with an optional reducer. The 100D model uses the same 2.2" focuser that can be found on the FC-60.

Questions & Answers

Product Questions

What tubes and connectors come for visual use? In pic I see the connector that screws onto draw tube, an extension tube, the visual connector, and then the step down to 1.25" and chrome compression ring. Do all those come with the 100DC so all I need is a 1.25" diagonal?

Is it possible to use 2" diagonals and 2" eyepieces, e.g. TV 35 Panoptic on the DC model scope? If so, what adapters are needed?

Thank you.
