Sky-Watcher Wave Counter Weight Kit

Sky-Watcher Wave Counterweight Kit – Precision Balance for Your Tracking System

If you’ve invested in Sky-Watcher’s high-performance Wave 100i or Wave 150i Harmonic Drive Mount, you already know how smooth and compact these mounts can be. But even the most advanced harmonic drive systems benefit from fine-tuned balance—especially when you’re pushing your payload limits with heavy imaging gear, long optical tubes, or off-axis guiding setups. That’s where the Sky-Watcher Wave Counterweight Kit comes into play.

This optional counterweight system is designed specifically for the Wave mount series, offering additional control over balance and improving the overall performance of your rig—especially when operating near the upper end of the mount’s capacity.

Purpose-Built for the Wave Series

The Wave Counterweight Kit isn’t a one-size-fits-all solution. It’s custom-engineered to integrate seamlessly with the Sky-Watcher Wave mount body, maintaining the clean, compact form factor while delivering practical functionality. The counterweight shaft threads securely into the base of the RA axis and provides a low-profile solution for mounting the included counterweight without interfering with your cabling or polar alignment routine.

This isn’t about old-school equatorial balancing for the sake of tradition—it’s a purposeful design for modern imaging rigs that demand performance and stability, especially with longer setups or uneven gear distribution.

Improve Harmonic Mount Performance Under Heavy Load

Harmonic drive mounts like the Wave 100i and 150i are well-known for their ability to carry unbalanced loads without a traditional counterweight system. But “can” and “should” aren’t always the same thing. If you’re operating at 90–100% of the rated capacity, or running an off-kilter setup with a heavy camera, filter wheel, or guidescope far from the center of mass, you may see subtle issues creep into your guiding—backlash, oscillation, or tracking corrections that don’t quite settle.

By reintroducing a small, precise amount of counterbalance, the Wave Counterweight Kit helps reduce strain on the RA motor and improve tracking accuracy. It’s a smart way to increase your guiding precision and keep your harmonic mount performing at its best when fully loaded.

Kit Includes Everything You Need

The kit consists of a stainless steel counterweight bar 0.79-inch (20mm) diameter x 12.4-inch (314mm) length, and an extension bar 0.79-inch (20mm) diameter x 6.5-inch (164mm) length.  These two pieces will add under 2.5 pounds in total to your mount head.  The kit also comes with an 11 pound counterweight rounding out all the items you should need for that extra bit of payload you want your mount to carry.

A Thoughtful Addition for Advanced Imaging Setups

Whether you’re running a compact imaging rig or maxing out your payload with a large refractor and a full complement of accessories, the Wave Counterweight Kit gives you more control over your system’s balance and tracking behavior. It’s a smart investment for astrophotographers who want to squeeze every last bit of precision out of their mount—especially those pushing the performance envelope.

This kit doesn’t just help your mount—it helps your data. Better balance means smoother guiding, fewer corrections, and cleaner subs. That’s the kind of upgrade that pays off night after night.
