CAA Reducer Coupling for Takahashi FSQ-106EDX refractor. Number 17 on the System Chart.
The Takahashi TKA36002 Reducer Coupling was designed specifically for the FSQ-106ED Camera Angle A. Item #17 on Takahashi FSQ-106 ED Photo-Visual Systems Chart.
The TRDC0106 Takahashi Reducer Coupling is made to sit inside the Camera Angle Adjuster (CAA) on the FSQ-106ED telescope on one end, and the 0.73X Reducer on the other. This negative length 92mm - 72mm adapter puts the reducer inside the CAA so that it can reach infinity focus using the standard TCA1020 and TCDXXXX adapter for your specific CCD camera.
