The tube ring pairs and tube rings connect our telescopes to the carrying mechanism - so the use of these rings is essential for medium and larger telescopes, and necessary for smaller telescopes when using precision mechanisms.
In the opening rings, we insert the tube (see photos), and then close the ring with the screws - this "captures" our scope. Then we attach the chosen prismatic lens to the bottom of the ring , which can then be easily inserted into the specially designed part of our mechanism. And you have your skywatcher ready to go.
In addition to "holding" the telescope, tube rings have other, additional functions - in many cases they become carriers themselves. At their upper point, opposite the prismatic lens, they can optionally be used to hold a variety of devices: a camera, a guide ring with a guide telescope (for astrophotography), etc.
The rings are made of aluminium - this ensures both lightness and a strong and solid support for your favourite and precious telescope.
