This threaded extension provides the necessary 2\" of additional spacing between the focuser body and the Apex threaded adapter. By threading directly onto the focuser, it creates a rigid, secure, and perfectly square connection for your imaging train, preventing any tilt or flex that could compromise your final image.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhy is the Apex ED Threaded Extension required for the Esprit 120 and 150?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Starizona ApexED 0.65x reducer needs to be placed at a specific distance from the telescope's optics to function correctly.
