This 200mm shaft provides the extra length needed to increase leverage, allowing you to balance heavier camera rigs on your SkyGuider Pro or HAE mount effectively. This means you can use your existing counterweights or fewer weights overall to achieve stable tracking.\u003c\/p\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"DAV-bg-light\"\u003e\n    \u003cdiv class=\"DAV-section\"\u003e\n      \u003ch3\u003eSecure Fit: 20mm Diameter with Included Safety Screw\u003c\/h3\u003e\n      \u003cp\u003eEngineered to match iOptron's standard, the shaft's 20mm diameter ensures a perfect fit for all SkyGuider Pro and HAE-compatible counterweights. A key feature is the included safety screw at the end of the shaft, which acts as a stop to prevent a counterweight from accidentally sliding off during setup or adjustment. For maximum flexibility, the shaft is threaded with a 3\/8\"-16 thread on both ends, allowing you to connect two shafts for extreme payloads.\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\"\u003eWhat mounts is the iOptron 200mm counterweight shaft compatible with?\u003c\/h3\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion-A\"\u003e\n    \u003cp\u003eThis counterweight shaft is designed specifically for iOptron's \u003cstrong\u003eSkyGuider Pro (SGP)\u003c\/strong\u003e and \u003cstrong\u003eHAE series\u003c\/strong\u003e equatorial mounts, featuring a standard 20mm diameter.\u003c\/p\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion\"\u003e\n    \u003ch3 class=\"DAV-accordion-Q\"\u003eWhy would I need this 200mm shaft for my SkyGuider Pro?\u003c\/h3\u003e\n  \u003c\/div\u003e\n  \u003cdiv class=\"DAV-accordion-A\"\u003e\n    \u003cp\u003eYou need the extended 200mm shaft when your imaging payload becomes too heavy or long to balance with the stock shaft.

Because the shaft has a 3\/8\"-16 thread on both ends, you can directly connect a second shaft to the first for a combined 400mm of length.
