Sky-Watcher 1.7kg Counterweight for EQ3 EQ5 - White

The Sky-Watcher 1.7kg White Counterweight is a practical balancing solution designed for astronomers who require precise stabilization for their telescope setup. Whether you are fine-tuning weight distribution for visual observing or astrophotography, this counterweight helps maintain accurate tracking by reducing strain on your mount’s motors and gears. At 1.7 kilograms, it is the ideal choice for users who frequently adjust their optical configurations or add accessories like cameras, guide scopes, and larger eyepieces. Unlike heavier weights that can over-compensate, this lightweight counterbalance allows for small, effective adjustments without introducing unnecessary mass to your equipment.

Engineered for seamless integration, this compact counterweight is compatible with Sky-Watcher mounts featuring a standard 19–20mm shaft, securing firmly in place to ensure dependable stability. It is finished in Sky-Watcher’s signature white coating, allowing it to blend beautifully with modern telescope aesthetics while offering durable, long-lasting performance. Easy to install and highly dependable, this weight is a valuable addition for any astronomer seeking enhanced precision and optimized mount efficiency during extended imaging or observing sessions.

Product Features in Detail

Precision Balancing for Specialized Gear

With a specific mass of 1.7kg, this counterweight is designed for the subtle art of fine-tuning. It is the perfect solution for astronomers who add small but significant accessories to their setups—such as guide scopes, dedicated astro-cameras, or heavy 2-inch eyepieces—allowing for exact balance without the "over-compensation" issues common with heavier 5kg weights.

Optimized Mount Efficiency and Longevity

Achieving a perfect balance is not just about stability; it is about protecting your investment. By using this counterweight to find the center of gravity, you significantly reduce the physical strain on your mount’s internal motors and brass gears. This ensures smoother tracking for astrophotography and prevents premature mechanical wear over years of use.

Seamless Sky-Watcher Ecosystem Integration

Engineered specifically for the Sky-Watcher family, this weight features a bore diameter perfectly suited for the 19mm to 20mm counterweight shafts found on EQ3 and EQ5 mounts. It integrates flawlessly with the existing hardware, ensuring a snug fit that eliminates vibrations and prevents the weight from shifting during steep slews.

Signature Aesthetic and Durable Finish

This accessory is finished in Sky-Watcher’s signature high-gloss white powder coating. Not only does it provide a professional, unified look when paired with modern "Black Diamond" or white optical tubes, but the coating also acts as a durable barrier against the moisture, dew, and temperature fluctuations typical of nighttime observing.

Secure Dual-Surface Locking Mechanism

Safety is paramount when suspending heavy metal weights above expensive equipment. This counterweight features a robust locking screw designed to grip the shaft firmly. This ensures the weight remains locked in place even during "meridian flips" or when the telescope is pointed at the zenith, providing total peace of mind during unattended imaging sessions.

Compact and Travel-Friendly Design

For the mobile astronomer, every kilogram and centimeter counts. The compact profile of the 1.7kg weight makes it much easier to pack into equipment cases compared to larger, bulkier alternatives. It offers a "grab-and-go" balancing solution for field trips where portability is just as important as performance.
