TAKAHASHI FC-100DC/FC100DF
* More Beautiful refractors from Takahashi *

The FC100DC and FC100DF return to the days of beautiful long focus doublet refractors, which Takahashi did so well before they introduced compact travel scopes. The models have the identical object lenses, the DC model have the same focuser as FS-60, and the DF model having the same focuser as Sky 90.
Thus the DC model is cheaper and lighter, and uses the same focal reducer as the FC-76DC (also a lot cheaper). So why one asks would you go for the DF model? The key here is that the image circle is a lot larger. The FC-35 focal reducer has a 44mm diameter image circle, enabling full frame CCD and DSLR cameras to be used, whereas the 76DC focal reducer has a 30mm diameter image circle. This though is fine for CCD/CMOS chips up to 2/3 full frame, so will be perfect for a great many users.
