iOptron 2.2 lb Counterweight for SmartEQ and SmartEQ Pro
Part Number: 3106-02
Compact Balance for Lightweight Mounts
The iOptron 2.2 lb (1 kg) counterweight is a precision-balanced solution designed specifically for the SmartEQ and SmartEQ Pro mounts. When you're working with compact, portable equatorial systems, even a small imbalance can affect slewing accuracy, tracking precision, and motor performance. This lightweight counterweight allows you to restore proper equilibrium when using slightly heavier accessories or telescopes than your stock configuration was designed for.
Whether you're running a compact refractor, a DSLR, or a small guide scope, this weight provides just enough extra mass to get your rig dialed in—without overloading the system.
Designed for 16mm Counterweight Shafts
This counterweight is machined to fit 16mm diameter counterweight shafts, the standard used on both the SmartEQ and SmartEQ Pro. It includes a built-in hand-tightening knob that allows you to attach or reposition the weight easily in the field—no tools required.
Its compact profile—measuring approximately 3" in diameter and 1" tall—makes it ideal for travel and field use. The black finish matches iOptron’s standard mount aesthetic and blends in cleanly with your existing gear.

Observing Tip
If you're using the SmartEQ or SmartEQ Pro with a DSLR or heavier eyepieces, this 2.2 lb counterweight is an excellent way to restore balance without carrying an extra full-size weight. Keeping your system in balance not only improves GoTo accuracy but also extends battery life—since unbalanced systems force the motors to work harder than they need to.
Final Thoughts
The iOptron 2.2 lb Counterweight (#3106-02) is a must-have accessory for any SmartEQ or SmartEQ Pro user looking to expand their payload slightly without compromising performance. Lightweight, durable, and easy to install, it gives you just the right amount of counterbalance to keep your mount performing at its best—especially when you're traveling light.
