The Takahashi TOA-35 reducer shortens the focal length of TSA/TOA telescopes to widen the field of view when photographing with the same sensor. Its nominal factor of 0.7× allows for a reduced-focal-length photographic setup.
The assembly depends on the telescope. On the TSA-120, the Takahashi diagram shows the TOA-35 installed after the CAA-M TKA23200N rotating collar, followed by the CA Ring 150 TKA32202 and the photo ring adapted to the housing. Part number TKA32580 refers to the reducer alone; the TKA32580NS kit combines this reducer with the CA Ring 150.
