Sky-Watcher 90 mm Tube Rings - Set of 2
Looking for a reliable way to secure your Sky-Watcher refractor tube? This set of two tube rings is exactly what you need. They hold the tube firmly on the mount and keep it stable even during longer observing sessions.
Secure fit for your refractor
The rings have an inner diameter of 90 mm and fit refractor tubes with a 90 mm outer diameter. A typical compatible model is the Sky-Watcher 90/900 or 80/400 refractor. With two rings supporting the tube at different points along its length, flexing and vibration are kept to a minimum.
Why good tube rings matter
Tube rings are a key part of your whole observing setup. Well-made rings prevent the tube from shifting on the mount, keep the optical axis correctly aligned, and make it easier to balance the telescope. If you plan to do astrophotography or long visual observing sessions, reliable tube rings are essential.

These are genuine Sky-Watcher accessories from one of the world's leading manufacturers of astronomical optics. Genuine parts fit together perfectly - no modifications, no compromises.
