Takahashi Aux Ring for TOA‑130/FSQ‑130ED with 0.7× 645 Reducer (TKA38206)

This black-anodized M98 ring fills the 55 mm spacing gap required when coupling the 0.7× 645 reducer with TOA‑130 or FSQ‑130ED systems. With a sturdy, knurled build and precise threading, it's essential for achieving full frame coverage without pushing the focuser to its limits.

Cloudy Nights Community Insight:
Photographers frequently mention that with this ring installed, focus becomes attainable “without stressing the focuser or losing image consistency”—vital for long sub-exposure imaging setups.

Observing Tip:
Install this ring before the reducer when building the imaging train. It keeps the system balanced and secures the reducer position under load.
