The Takahashi FC-35 reducer shortens the focal length of the FC-100DF and FC-100DZ to capture a wider field of view. The catalog lists a focal length of 480 mm at F/D 4.8 with the FC-100DF and 530 mm at F/D 5.3 with the FC-100DZ, with an image circle of 44 mm in both configurations.
The photo montage follows the layout for each telescope: the CA Ring 100D TKA19202 is paired with the FC-100DF, and the CA Ring 102 TKA23202 with the FC-100DZ. Choose the adapter ring for your camera body based on this same diagram.
