The M65×1 adapter for ARCO 3" (PrimaLuceLab, SKU: PL3600468 ) allows you to directly attach the ARCO 3" rotator to focusers or correctors equipped with an M65 × 1 (female) thread. The adapter screws into the telescopic side of the rotator, providing an axial, rigid connection and adding only 3.5 mm to the optical path length.
