Focusing systems for telescopes: how to choose the best solution among SESTO SENSO and ESATTO

Our ESATTO and SESTO SENSO are the best focusing systems. They share the same features but they have a different design. Which one to choose? Both have the USB-C type port for computer connection, the port to connect the optional ARCO rotator, the 12 volts power port, the port for the temperature probe, dimmable LEDs and Wi-Fi connectivity in order to control them from a smartphone or a tablet, but SESTO SENSO is a robotic focusing motor that we designed in order to easily connect to your telescope focuser and use it in order to properly focus your telescope. While the ESATTO is a complete robotic microfocuser that is perfect for telescopes that haven’t a very precise and high load capacity focuser. This way we suggest the use of the SESTO SENSO if you want to use your telescope both for visual or for astrophotography.

This way you install 01:10 - SESTO SENSO on your original focuser and you can keep your original focus draw tube travel but if you have an heavy camera and you want to use your telescope for astrophotography you may want to install the ESATTO instead. ESATTO is perfect for telescopes like Schmidt-Cassegrain or Aplanatic Schmidt-Cassegrain where you can keep the original focuser as a course knob and then you focus precisely with the ESATTO avoiding any focus shift. SESTO SENSO or ESATTO? Robotic focus motor or robotic microfocuser? In any case you have the best focusing solution! .
