Then, by using the provided Allen screw, please fix the screws that fix the outer ring of SESTO SENSO 2 to your
focuser.
Finally, use the Allen screw to lock the 3 small grub screws fix the outer ring of SESTO SENSO 2 to your focuser.
NOTE: After installing SESTO SENSO 2 on your focuser, check the smoothness of the movement keeping SE-
STO SENSO 2 powered off and then manually moving the focus knob of your focuser. The presence of SESTO
SENSO 2 will make the movement harder (since the motor is connected) but the motion must still be uniform. If
you notice an uneven movement, repeat the installation procedure.
NOTE: SESTO SENSO 2 connects to several focusers that may have different machining and tolerances preci-
sions. Focusing accuracy, especially when using automatic focusing procedures, depends on the focuser me-
chanics and not only strictly on SESTO SENSO 2. If your focuser has an important backlash, you can adjust the
backlash parameter in the software.
