Focal Reducers and Flatteners

Takahashi 645 REDUCER 0.7X (FSQ-130ED) Reduces the focal length of the FSQ-130ED telescope by 0.7X, increasing the speed of the optical system for astrophotography. Produces a 70 mm diameter image circle that is ideal for larger imaging chips.  

Takahashi 645 Reducer QE 0.72x (FSQ-106)

Takahashi 645 REDUCER-CA (.72X) (CCA-250) Reduces the effective focal length of the CCA-250 telescope by 0.72X, increasing the speed of the optical system for astrophotography.   Produces a 60 mm diameter image circle that is ideal for larger...
