ARCO 3" Camera Rotator and Field De-Rotator

Description:

ARCO 3" is the larger version of PrimaLuceLab’s high-resolution camera rotator, offering an exceptional precision of 1 arcsecond per step. Designed for astrophotographers demanding the highest level of accuracy, ARCO 3" provides both camera rotation and field de-rotation functionalities in a compact, robust housing.

With only 23 mm thickness and a wide 76.3 mm clear aperture, ARCO 3" integrates seamlessly into any optical train. Thanks to its dedicated connection to ESATTO or SESTO SENSO 2 systems, it operates without the need for additional USB or 12V power cables. All connections and controls are managed through a single short cable.

ARCO 3" is fully compatible with PrimaLuceLab’s PLAY astrophotography software, allowing precise control of camera rotation and de-rotation, as well as full telescope configuration using ASCOM-compatible mounts. The dedicated ASCOM driver also supports third-party software integration.

Constructed with a precision-machined aluminum case, ARCO 3" supports heavy cameras and accessories without introducing flexure. Optional adapters allow seamless connection to a variety of focusers and optical components, including all M81 accessories with stop ring.

It can be easily adapted to ESATTO 3" and 4" focusers using the PL3600458 and PL3600459 adapters. For setups with SESTO SENSO 2, optional adapters are available for M63x1 and M86x1 threads. Additionally, ARCO 3" supports a wide range of M-thread adapters to connect with T2, M48, M54, M57, M68, M72, and 2” visual accessories.
