ZWO BC230 Counterweight Bar – Precision Balance for Your Astrophotography Rig

If you're running a fully loaded astrophotography setup, balance is everything. The ZWO BC230 Counterweight Bar is designed to provide a seamless weight adjustment solution for users of ZWO's AM3 and AM5 strain wave drive mounts. Whether you're fine-tuning balance for a heavy imaging train or just need a bit of extra stability, this precision-engineered counterweight bar ensures your mount operates smoothly and efficiently.

Designed for Stability and Smooth Tracking

The BC230 counterweight bar allows you to add counterweights to your ZWO mount, optimizing balance and reducing strain on your system. Proper balance is essential for achieving accurate tracking, minimizing guiding corrections, and reducing stress on the mount’s motors. If you're working with a larger refractor, a fully outfitted astrograph, or an extensive imaging setup, the BC230 gives you the flexibility to fine-tune your rig for optimal performance.

High-Quality Construction

Crafted from high-strength stainless steel, the BC230 is built for durability while maintaining a sleek, compact design. The precision-machined threading ensures a secure fit with your mount, preventing any unwanted movement during long-exposure imaging sessions. Measuring 230mm (9 inches) in length, the bar provides ample space for various counterweight configurations, allowing you to fine-tune your system's balance with ease.

Perfect Fit for ZWO AM3 and AM5 Mounts

The BC230 is specifically designed to work with ZWO's AM3 and AM5 harmonic drive mounts, offering a direct-fit solution that integrates seamlessly with your existing setup. Whether you’re using the AM5 for a portable deep-sky imaging rig or pushing the AM3 to its limits, this counterweight bar gives you the flexibility to compensate for a wide range of payloads.

Adaptable to Your Setup

Different astrophotography setups demand different balancing solutions. The BC230 works with standard counterweights, allowing you to customize the amount of weight based on your telescope and imaging equipment. If you're using a long focal length OTA, a heavy dedicated astro camera, or additional accessories like guidescopes and filter wheels, this bar gives you the freedom to distribute weight exactly where it's needed.
