ESATTO 3" EXTENSION TUBE 65mm

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 has designed this 65mm extension that can be installed between ESATTO 3" and the telescope tube. A precise dovetail coupling system with 3 screws set at 120° allows you to manually rotate the focuser.

Two M5 screw holes are included on the side of the extension at a distance of 22mm centre-to-centre for connecting a finderscope saddle such as the PLLBACEDX DX Finder Base.
