Whether you're looking to upgrade your mount or simply swap out a component, the counterweight plays a crucial role in maintaining the balance of your optical tube assembly (OTA) and any add-ons like cameras or guiders. If your setup is feeling a bit lopsided due to added gear, throwing in an extra counterweight can help you achieve that sweet balance.

However, don't just slap on a counterweight and call it a day; improper balance can lead to a range of problems, from damaging your OTA and mount to messing up your motor gear and tracking precision. Distributing counterweights evenly along the shaft is key, so make sure you give some thought to placement. And, of course, you'll want to make sure adding that extra counterweight is both a cost-effective and necessary move for your specific setup.

Our counterweight is built to last, featuring a robust knurled knob that securely locks it onto a 19mm counterweight shaft.
