With a standard 19 mm (0.74 in.) diameter, it accepts common small counterweights and attaches securely to the mount head via its M14 female thread.

For visual use with standard 1.25\" eyepieces, a 90mm Maksutov is usually light enough not to require counterweights. However, if you add a heavy 2\" diagonal, a large eyepiece, or a camera to the back, the scope will become back-heavy. In that scenario, this 150 mm shaft and a small counterweight would be necessary to restore balance.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use the Cube Counterweight shaft to balance a short-tube 80mm refractor with a camera?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, this is an ideal use case. An 80mm refractor, especially with a field flattener and DSLR or dedicated astronomy camera attached, creates a significant load that must be balanced.
