It introduces an integrated position encoder that permits manual focuser adjustments without losing calibration, a Self Centering Clamp 2 (SCC2) for rapid installation without external brackets, and both USB-C and WiFi connectivity for complete control. You can operate the SESTO SENSO 3 from a computer via its ASCOM driver or PLAY software, or wirelessly from a smartphone using the Virtual HandPad.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eIntegrated Encoder: Manual Focusing Without Losing Calibration\u003c\/h3\u003e\n      \u003cp\u003eThe standout feature of the SESTO SENSO 3 is its integrated position encoder. This system precisely tracks the focuser shaft's movement, allowing you to make manual adjustments with the original focuser knob at any time without the motor losing its calibrated position. This is ideal for observers who switch between visual use and astrophotography.\u003c\/p\u003e\n      \u003cp\u003eFor added security, the Automatic Position Recovery function can be enabled. If the focuser is accidentally moved, this feature automatically returns it to the previous position after a user-defined delay, protecting your focus during public outreach events or unattended remote sessions.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eFlexible Control: USB-C, WiFi, and Virtual HandPad\u003c\/h3\u003e\n      \u003cp\u003eThe SESTO SENSO 3 offers modern, reliable connectivity options for any workflow.
