Easy installation and broad compatibility
Thanks to new technology SCC2, The SESTO SENSO 3 attaches directly to most eyepiece holders without the need for an external support. It is compatible with a wide range of instruments such as :
SkyWatcher EVOSTAR, EVOLUX, ESPRIT, Newton and Quattro
The port USB-C guarantees a fast, reliable connection, while the Integrated Wi-Fi offers wireless control via smartphone or tablet. The software PLAY provides intuitive engine control, auto-tuning, temperature management and real-time system status monitoring.
Compatibility with ARCO
Connect the ARCO rotator for motorized camera rotation or field de-rotation on alt-azimuth mount. A single cable is all you need for power and data transfer.
