About this product
Part Number: PL3600284
When installing the ESATTO 3" Focuser in a telescope with a long travel focuser (normally found on refractors), it is necessary to take into account the shorter travel of the ESATTO 3" (due to it being a micrometric focuser).
For this reason PrimaLuce have designed this 65mm extension that can be installed between the ESATTO 3" Focuser and the telescope tube. A precise dovetail coupling system with 3 screws set at 120° allows you to manually rotate the focuser.
