The ESATTO 3" → Takahashi TSA-120 adapter (PrimaLuceLab, SKU: PL3600296 ) allows you to replace the factory Takahashi TSA-120 apochromat focuser with a remote-controlled, precision ESATTO 3" focuser. The collar uses the original hole spacing of the refractor's rear cell, making the mount non-invasive and the telescope's designed back-focus fully preserved.
