The Bresser tube ring stirrup with main thread can be used with Bresser 90 mm tubes or SkyWatcher 80 and 90 mm objective tubes.

The tube ring stirrups connect our binoculars to the carrying mechanism with the vixen mounting system. The product comes with a vixen-compatible prism rail design so you don't even need to buy one separately.

We insert the tube into the folding stirrup, then close the stirrup with the screw - thus "holding" our scope. If you don't want to use it for a Bresser product, but for telescope building, the good news is that we also provide a short tube as a gift with the slip-on, but in this case you will have to make some kind of intermediate piece yourself.

Optionally, you can mount a variety of devices on the top - opposite the prismatic lens: a camera, etc.
