Sky-Watcher Tube Rings 160 mm - Set of 2
A secure tube connection is the foundation of reliable and comfortable observing. If you own a Sky-Watcher 130 mm reflector telescope - such as the popular Sky-Watcher 130/650 or Sky-Watcher 130/900 - these Sky-Watcher tube rings with a 160 mm inner diameter are designed precisely for the outer diameter of those tubes. The set includes two rings, which is the minimum needed for even and safe tube mounting on a mount - without any risk of tube flex or unwanted vibrations.
Precision fit and reliable clamping
Each ring is manufactured to Sky-Watcher quality standards. The 160 mm inner diameter matches the outer diameter of the compatible reflector tubes exactly. The clamping elements grip the tube evenly without deforming it, and the build quality handles regular use both in the field and at a fixed observing site. You do not need to worry that uneven tightening will cause tube flex or affect the pointing accuracy of your mount.
When do you need replacement tube rings?
Tube rings are one of those accessories that are easy to overlook - until you actually need them. There are several situations where a replacement set becomes essential:
- You are moving the tube to a different mount
- You are building a custom telescope cradle or a parallactic cart
- The original rings are damaged or no longer tighten properly on the tube
In all of these cases, having the correct original replacement part means everything fits together as intended. The set of two rings also ensures even weight distribution along the tube axis. This is especially important in astrophotography with longer exposures, where even minor vibrations or tube flex can cause blurring in your images.
