TAKAHASHI
The Takahashi FC-100DC apochromatic telescope is designed around a fluorite doublet at F/D 7.4. Designed primarily for observation, it still allows the use of small cameras in astrophotography.

FC-100DC (OTA) WITH 31.75 ADAPTER
The Takahashi FC-100DC apochromatic telescope is designed around a fluorite doublet at F/D 7.4. It is equipped with a 31.75 mm compact rack-and-pinion focuser, inherited from the FS-60CB. It is much lighter than its big sister FC-100DF, only 2.8 kg compared to 3.6 kg for the FC-100DF. A small mount will be enough to make the most of it. Designed primarily for observation, it still allows the use of small cameras in astrophotography.
Photography at the native focal length of the refractor requires the 76D field corrector (or the multi-flattener). The FC-100DC can also be equipped with the 76D-RD focal reducer.
The user of large sensors, in APS-C or higher format, will prefer the FC-100DF model and its dedicated focal reducer, the FC-35RD.
