Installing SESTO SENSO 2 on the telescope’s focuser
In order to connect SESTO SENSO2 to the focuser of your telescope, remove the manual focus micrometric knob
by unscrewing the screw normally present on the knurled knob. After pulling it out, you also need to disconnect the
coarse focuser knob, by means of an Allen screw on the knob. On some plastic-covered focusers, you need to re-
move the plastic to access the disassembly screw. Connect one of the bushings you find in the SESTO SENSO 2
box (based on the diameter that fits your focuser) to the small focuser shaft of your focuser.
Now you can connect SESTO SENSO 2 to your focuser by paying attention to centering the micrometric pin with
the pre-assembled bushing on SESTO SENSO 2, until it stops. By using the provided Allen screw, lock the 2 grub
screws that fix the pre-assembled bushing on SESTO SENSO 2 to the bushing you just installed on your focuser's
shaft.

NOTE
in order to work, SESTO SENSO 2 requires
your focuser to have the micro metric knob.
NOTE
SESTO SENSO 2 is designed to be connec-
ted to 25mm shaft. If you have another dia-
meter, you may add the optional 26, 33 or
37mm adapters. Please refer to page 25 in
order to know how to install the adapters.
