This M81 extension tube has 25mm thickness, it's made up of aluminum, black anodized and it has a M81 female on the camera side this way you can connect all the ESATTO 3\" camera adapters.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003ePrimaLuceLab 40mm extension tube for ESATTO 3\"\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eWhen 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 we have designed this 40mm 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003ePrimaLuceLab 65mm extension tube for ESATTO 3\"\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eWhen 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.
