The SESTO SENSO 3 SC is a high-performance robotic focusing motor engineered for Schmidt-Cassegrain (SC), EdgeHD, RASA, and similar telescopes with internal focusing mechanisms. Built for demanding astrophotographers, it delivers precise, repeatable focus control and seamless integration with modern astronomy setups.
Key Features
- All-in-One Compact Design: Houses all electronics in a lightweight enclosure, minimizing load on your telescope.
- Direct Pulley Clamp (DPC): Provides backlash-free, pulley-driven coupling for smooth, precise motorized and manual focusing.
- Integrated Encoder: Tracks focuser position even during manual adjustments, with Automatic Position Recovery to restore focus if moved.
- High-Resolution Motor: Offers up to 2 million steps for fine control of internal mirror focusers.
- USB-C and WiFi Connectivity: Control via computer, smartphone, or tablet using the Virtual HandPad—no physical hand controller required.
- Software Compatibility: Works with PrimaLuceLab PLAY software (including autofocus and temperature compensation) and ASCOM drivers for use with popular third-party astronomy applications.
- ARCO Rotator Port: Directly connects to the ARCO camera rotator for streamlined cable management and enhanced automation.
- DARK Mode: Dimmable or fully switchable-off LED indicators to protect night vision during imaging sessions.
- Temperature Sensor Port: Supports automatic focus compensation based on ambient temperature changes (sensor optional).
