iOptron HAZ46 Counterweight Shaft & Adapter

While the iOptron HAZ46 harmonic mount is built to carry impressive payloads without a counterweight, certain gear combinations—especially longer optical tubes or dual-saddle setups—can benefit from fine-tuned balance. That’s where the iOptron #8459 Counterweight Shaft and Adapter come in.

This accessory package includes everything you need to add a counterweight to your HAZ46 mount. Whether you're optimizing for smoother tracking, minimizing strain on the drive system, or balancing a heavy imaging train, this add-on delivers added versatility without compromising the HAZ46's portable, gear-driven performance.

What’s Included:

• Threaded Counterweight Shaft: A precision-machined stainless steel shaft designed to screw securely into the adapter base. The shaft is compatible with iOptron's standard 20mm bore counterweights (sold separately), such as those used on CEM26, GEM28, and other lightweight iOptron mounts.

• Custom Adapter for HAZ46: This anodized aluminum adapter bolts directly to the HAZ46’s dovetail saddle base, providing a stable mounting point for the counterweight shaft. It’s designed to integrate cleanly with the HAZ46’s form factor, maintaining a low profile when installed.

• Mounting Hardware: All necessary bolts are included for secure attachment. Installation requires only basic tools and takes just a few minutes.

Key Features:

• Increases Mount Versatility: Helps achieve better balance with longer optical tubes, off-axis guiders, or heavy filter wheels—especially in dual-saddle or side-by-side configurations.

• Stainless Steel Shaft: Provides a rigid, vibration-resistant anchor point for counterweights. Threaded end ensures secure mounting without wobble or loosening.

• Precision Fit: The adapter is machined to mate cleanly with the HAZ46 body for a secure and stable connection.

• Supports Standard iOptron Counterweights: Accepts counterweights with a 20mm center hole, such as iOptron’s 5kg and 10kg weights.

• Field-Friendly: Compact and easy to install, making it ideal for traveling astronomers or those who switch between visual and imaging setups.

• Shaft Material: Stainless steel

• Counterweight Compatibility: 20mm bore (standard iOptron)

• iOptron Part Number: 8459

Observing Tip:

Even if your mount “doesn’t need” counterweights, improved balance can reduce harmonic vibration and improve tracking accuracy in windy conditions or at longer focal lengths. Adding a counterweight isn’t always about capacity—it’s about control.
