Celestron Counterweights for 19mm Shafts – Balance for Peak Mount Performance

Optimise Your Telescope Balance for Smooth Tracking and Motor Longevity

Whether you're upgrading your astrophotography rig or replacing essential hardware, a properly balanced mount is critical for precision tracking and reliable operation. These Celestron counterweights are specifically designed to offset the weight of your optical tube assembly (OTA) and any additional accessories—such as cameras, guide scopes, or filter wheels—on the opposite side of the Right Ascension (RA) axis.

Why Counterweight Balance Matters

An imbalanced setup can lead to:

  • Increased strain on motors and gears

  • Decreased tracking accuracy

  • Potential long-term mechanical wear

Adding the correct counterweight improves balance and reduces mass inertia, ensuring smoother slewing and tracking. For best results, distribute the weight evenly along the counterweight shaft for optimal performance and minimal stress on the system.

Rugged Design with Secure Locking

Each counterweight features:

  • A durable metal construction for long-lasting reliability

  • A knurled locking knob that fastens securely to 19mm (0.75") shafts

  • Compatibility with multiple Celestron German equatorial mounts

Does it come with a warranty?

All our products are UK stock so come with manufacturers warranty

What happens if I don't like it?

We always want you to be happy with your purchase — so if you’re unsure, please ask us first. We’re always happy to give honest advice before you buy.

If the product arrives and you simply decide it isn’t for you, you can usually return it within the cooling-off period — as long as it’s unused, in perfect condition, and returned with all original packaging and accessories.

Because telescopes and optical equipment are large, delicate and expensive to ship, you’ll need to cover the cost of sending it back, and if we originally subsidised delivery, we may deduct our outbound shipping costs from your refund.

We’re a small specialist business, and unnecessary returns genuinely hurt us — so if you’re unsure at all, please talk to us first. We’d rather help you choose the right item than process a return.

How fast is shipping?

We aim to ship in-stock items as quickly as possible.

  • Most in-stock orders dispatch within 1–2 working days
  • Delivery usually takes 1–3 working days after dispatch (UK mainland)
  • Heavier / oversized items and special orders may take a little longer

You’ll receive tracking details as soon as your order is on its way.

Astronomy equipment often requires specialist packing and trusted couriers — we do this to keep your gear safe, not to slow things down. If you need something urgently, just ask and we’ll do our best.
