This adapter allows you to install the ESATTO 3" robotic focuser to the Skywatcher Esprit 120 ED & 150 ED apochromatic refractors. A precise dovetail coupling system with 3 screws set at 120° allows you to manually rotate the focuser.
Note - When installing ESATTO 3" in a telescope with a long travel focuser (such as those usually found on refractors), it is necessary to take into account the lower travel of ESATTO 3" since it's a micrometric focuser. For this reason Prima Luce Lab have designed a 65mm extension tube that can be installed between ESATTO 3" and the telescope. Additional extensions may be required depending on what accessories you use.
