This adapter allows you to connect the Prima Luce Lab ARCO 3" robotic rotator to the ESATTO 4" microfocuser and control it via the dedicated port on the ESATTO.
It has an optical thickness of 1.5mm, so adding this adapter will increase the thickness of the ARCO 3" from 23mm to 24.5mm.
Note: This adapter cannot be used to connect the Arco 3" to the Takahashi FSQ-106 series due to interference with the internal lens elements. Please contact us for an alternative solution.
