The PrimaLuceLab M56 to M57 adapter allows you to connect any accessory with an M57×0.75 female thread to the ESATTO 2" focuser or the ARCO 2" rotator. Simply thread this adapter to the ESATTO's M56 focuser draw tube, or the ARCO's M57 threads. When paired with the ESATTO, the provided stop ring lets you fix the accessory at a specific angle for accurate sensor alignment. When used with the ARCO, the adapter works as a connector/spacer, allowing rotation and secure attachment without affecting backfocus.
- Optical length of adapter from M56 to M57 with stop ring for ESATTO 2" is 4 mm (1.5 mm adapter + 2.5 mm stop ring).
