Click here for a guide showing how to install the Sesto Senso 2 to your focuser.
SESTO SENSO 2 is the highly accurate, advanced, vibration free, robotic focusing motor for your telescope with an incredible precision of 0.7 microns.
SESTO SENSO 2 incorporates all the features of the previous version and it adds:
- USB-C port to connect it to any standard computer or EAGLE USB port. The USB-C port is a more sturdy, its connection is more reliable and it is also reversible for easier connections in the dark.
- Integrated Wi-Fi connectivity with Virtual HandPad to use it with a smartphone or tablet
- Self Centering Clamp (SCC) technology to connect it to focusers without using external brackets.
- Dimmable LED to reduce its light disturbance. Also the LED light can be turned off completely
- Compatible with ARCO camera rotator without the need for additional data or power cables.
Control via WiFi, from any smartphone or tablet via the Virtual HandPad
The SESTO SENSO 2 app can save preset settings to easily move the focuser to pre-determined positions. The Wi-Fi control works even if SESTO SENSO 2 is connected to a computer so you can control it simultaneously from 2 devices.
Easily connects to most focusers using the Self Centering Clamp (SCC) without the need of external brackets

I bought this to go with a new Esprit 120ED (also from Testar). It attaches easily and performs effortlessly. Beautifully built. Seamlessly integrated into the NINA platform.
Excellent product!
I would definitely buy this product again and highy recommend it.
Hightly responsive with no backlash.
Great software.
High quality build lives up to Prima Luce reputation.
Windows 11 install was challenging, but once installed all is working well.
It is well worth the extra 150$.
Can't review at moment as I have not fitted or used it. Going to dark sky workshop next week, may have coment later
Great, easy to fit, (Skywatcher quattro) set up to run in SGP, (needed a bit of google help to work out the numbers) and it works. makes a huge difference.
I bought the Sesto Senso to replace my broken zwo focuser. I am extremely happy with it paired with the skywatcher Evostar ED80. The stars are super sharp.
