The unit includes dimmable status LEDs, which can be turned off completely to minimize stray light during nighttime observing or imaging sessions. Connectivity is streamlined and efficient: a USB-C port allows connection to an EAGLE or any Windows® computer using the included USB cable; the dedicated ARCO port enables both power and control of an optional ARCO camera rotator through a single cable; the 12V power port (5.5\/2.5mm, center-positive) supplies power to both the motor and internal electronics using the included cigarette lighter-style cable (or by using an optional cable for direct connection to the EAGLE); and a temperature sensor port lets you connect the optional probe for use with third-party software that supports automatic focus compensation based on ambient temperature changes.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/Sesto_Senso_3_Components.jpg?v=1759269935\" alt=\"\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/p\u003e\n\u003ch3\u003eEasy installation with \u003cspan\u003eSelf Centering Clamp 2 (SCC2)\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp\u003eSESTO SENSO 3 uses the new Self Centering Clamp 2 (SCC2), an evolution of the original SCC system, to easily connect the motor to the shaft of most focusers without the need for external brackets. SCC2 now supports multiple shaft diameters (25mm, 26mm, 33mm, 37mm) allowing for faster installation, and improved mechanical coupling with a wider range of focusers, \u003cstrong\u003ewithout the need for other adapters\u003c\/strong\u003e. In fact now SESTO SENSO 3 connects directly to 37mm shafts and, by adding one of the \u003cspan\u003eincluded adapters\u003c\/span\u003e, can be connected also to 25mm, 26mm, and 33mm diameter shafts. Another advantage of the SCC2 technology is that you can always use the manual (coarse) knobs of your focuser, even if SESTO SENSO 3 is installed, and thanks to the integrated encoder you won’t lose motor position if SESTO SENSO 3 is active. SESTO SENSO 3 is compatible with many telescopes (included bushings: red for 2,5mm diameter, black for 2,8mm diameter, blue for 2,4mm diameter, green for 3,5mm diameter, silver for 3,1mm diameter, gold for 4mm diameter), like (but not limited to these):\u003c\/p\u003e\n\u003cp\u003eSkyWatcher EVOSTAR, EVOLUX and ESPRIT\u003cbr\u003eSkyWatcher Newton and Quattro\u003cbr\u003eTakahashi FSQ85 and FSQ106 with fine focus knob\u003cbr\u003eBaader SteelTrack® focusers\u003cbr\u003eFeatherTouch focusers\u003cbr\u003eGSO Ritchey-Chretien with 2\" and 3\" focusers\u003cbr\u003eExplore Scientific focusers\u003c\/p\u003e\n\u003ch3\u003e\n\u003cspan\u003eIntegrated encoder\u003c\/span\u003e: precise control with freedom of movement\u003c\/h3\u003e\n\u003cp\u003eSESTO SENSO 3 integrates a position encoder that tracks the movement of the focuser shaft with extreme accuracy. This allows the user to manually move the focuser, with SESTO SENSO 3 installed and powered on, using the focuser’s original knob without losing motor position. Perfect for users who switch between visual and imaging sessions, this also speeds up and improves the calibration process.\u003cbr\u003e\u003cbr\u003eAnother advanced feature is the \u003cstrong\u003eAutomatic Position Recovery\u003c\/strong\u003e function, which if enabled automatically restores the previous focus position if focuser movement is detected. This feature is particularly useful in public or educational observatories, where visitors or users may be tempted to manually turn the focuser knob or if the focuser is accidentally moved. Another useful application is when the focuser drawtube shifts under load (please note that SESTO SENSO 3’s encoder is able to detect only shaft movements, not internal focuser slips that cannot be corrected by just the focusing motor but depend on the focuser itself). If you enable this function, you can set a recovery delay (from 0 seconds for instant reaction up to 20 seconds) after which SESTO SENSO 3 automatically moves the focuser drawtube back to its previous position.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cspan\u003eUSB-C connectivity\u003c\/span\u003e to control it from a computer\u003c\/h3\u003e\n\u003cp\u003eSESTO SENSO 3 features a modern USB-C port for direct connection to your control device, whether it’s a standard Windows 10 or 11 PC or the EAGLE computer. The USB-C interface offers a range of benefits over traditional USB connections: it’s reversible, making it easy to plug in even in low-light conditions, and it ensures a secure and reliable connection that’s resistant to accidental disconnections—especially useful in mobile or remote observatory setups. Plus, the wide compatibility with standard USB-C cables makes it easy to integrate SESTO SENSO 3 into any modern astrophotography workflow without the need for proprietary connectors.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0851\/2766\/files\/Play_Software_Sesto_Senso_3.png?v=1759269934\" alt=\"\" style=\"display: block; margin-left: auto; margin-right: auto;\"\u003e\u003c\/p\u003e\n\u003ch3\u003eEasy control with \u003cspan\u003ePLAY astrophotography software\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp\u003eSESTO SENSO 3 integrates perfectly with PLAY, the powerful astrophotography software developed by PrimaLuceLab to simplify and enhance your astrophotography.

With ARCO, you can remotely adjust the rotation angle of your camera to achieve perfect framing of your target. If you’re using an alt-azimuth mount, ARCO also allows you to de-rotate the field during long exposures—eliminating the need for an equatorial wedge. SESTO SENSO 3 and ARCO are designed to work seamlessly together, requiring only a single short cable for both power and data.

This allows full freedom of movement while maintaining accurate position tracking — ideal for telescopes with internal mirror focusing systems like Schmidt-Cassegrain, EdgeHD, or RASA. Whether you’re switching between visual and imaging setups or simply need to make manual adjustments, SESTO SENSO 3 SC ensures that the focus position is always known and reliable.\u003c\/p\u003e\n\u003cp\u003eA key feature exclusive to SESTO SENSO 3 SC is the \u003cstrong\u003eAutomatic Calibration\u003c\/strong\u003e mode, which works in synergy with the integrated encoder to automatically detect the minimum and maximum travel positions of your SC-type focuser. This makes SESTO SENSO 3 SC an ideal solution even for remote observatories, since you can calibrate the focuser remotely without manual intervention — a capability not available in other SESTO SENSO 3 models. Please note that the encoder tracks motor shaft rotation only and cannot detect focus shifts caused by mirror flop or internal mechanical play. Another advanced feature is the \u003cstrong\u003eAutomatic Position Recovery\u003c\/strong\u003e function, which if enabled automatically restores the previous focus position if focuser movement is detected. This is especially useful in public or educational observatories, where users may manually turn the focuser knob, or if the focuser is accidentally moved. When this function is enabled, you can set a customizable recovery delay (from 0 seconds for instant reaction up to 20 seconds) before SESTO SENSO 3 SC returns to the previous focuser position.\u003c\/p\u003e\n\u003ch3\u003e\n\u003cspan\u003eUSB-C connectivity\u003c\/span\u003e to control it from a computer\u003c\/h3\u003e\n\u003cp\u003e\u003cmeta charset=\"UTF-8\"\u003e\u003cspan\u003eSESTO SENSO 3 SC includes a USB-C port that allows easy and direct connection to your Windows 10\/11 PC or to the EAGLE computer.
