Manual focusing is still possible at any time by rotating the lens’s focus ring, while the integrated encoder keeps track of the motor’s position—even after manual adjustments.

Ideal for astrophotographers who need to fine-tune focus manually before switching to fully automated control, this feature also improves the initial calibration process.\u003cbr\u003eAnother advantage of the integrated encoder is its ability to detect and compensate for small shifts in focus caused by lens mechanics.

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\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg title=\"SESTO SENSO 3 robotic focusing motor for external focusers\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/sesto-senso-3-robotic-focusing-motor-encoder_8a6aa38e-1319-4e1b-b28e-2d933b8b3a03.gif?v=1766572777\" alt=\"SESTO SENSO 3 robotic focusing motor for external focusers\" width=\"1000\" height=\"625\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\n\u003cspan\u003eUSB-C connectivity\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003eto control it from a computer\u003c\/h2\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.

To support light-sensitive environments, the LED brightness can be finely adjusted—or completely turned off—by enabling DARK mode through the PLAY software or ASCOM driver. This helps protect your night vision and eliminates unwanted illumination during imaging. When paired with an EAGLE control unit, DARK mode can be triggered automatically: as soon as an acquisition sequence begins in PLAY, the system disables all LEDs to ensure a fully automated and light-controlled astrophotography session.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg title=\"SESTO SENSO 3 SC robotic focusing motor for SC type telescopes\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0686\/0049\/6239\/files\/sesto-senso-3-sc-robotic-focusing-motor-DARK-mode_3f99a9c6-6453-44a6-be4f-5181d6ca1092.gif?v=1766572828\" alt=\"SESTO SENSO 3 SC robotic focusing motor for SC type telescopes\" width=\"1000\" height=\"579\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\n\u003cspan\u003eGHOST mode\u003c\/span\u003e\u003cspan\u003e \u003c\/span\u003econnectivity and easy firmware upgrades\u003c\/h2\u003e\n\u003cp\u003eSESTO SENSO 3 SC takes full advantage of GHOST mode when paired with an EAGLE computer, allowing you to operate the focuser without a USB cable—perfect to simplify your setup.
