The Prima Luce Lab ARCO is the new low profile ARCsecond resolution rOtator that, thanks to its incredible resolution of 1 arc second per step, is the most precise camera rotator and field de-rotator.

This adapter allows you to connect the Prima Luce Lab ARCO 2″ robotic rotator to the ESATTO 4″ microfocuser and control it via the dedicated port on the ESATTO.

Adding this adapter will increase the thickness of the ARCO to 21mm.
