PLL-3600284 - PrimaLuceLab 65mm Extension Tube for ESATTO 3"
PLL-3600284 - PrimaLuceLab 65mm Extension Tube for ESATTO 3"
About This Product
When installing the PrimaLuceLab 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 the ESATTO 3" since it's a micrometric focuser. For this reason PrimaLuceLab has designed this 65mm extension that can be installed between the ESATTO 3" and the telescope tube. A precise dovetail coupling system with 3 screws set at 120° allows you to manually rotate the focuser.
