Rotators

ARCO is the robotic ARCsecond resolution rOtator, with low-profile and high load capacity, specifically designed to work with ESATTO or SESTO SENSO 2. Thanks to the incredible resolution of 1 arcsecond per step and to the special design, it allows you to rotate the camera and to de-rotate the field!

Connect ARCO to ESATTO or SESTO SENSO 2 by using the special port and you won't need other USB or 12V power cables. ARCO is available in different versions based on the free aperture you need and many optional adapters are available in order to personalize your system.
