Bague d'arrêt de réglage fin Baader Hyperion 2" avec bague de serrage en laiton - 2958027

We ordered this Stop Ring because our Focal Extender would have hit the mirror in our star diagonal without it. Quality product from Baader who seems to cover all the bases in their portfolio. Works as expected, good fit, and 2 thumb screws for the brass ring ensure a solid connection. As expected prompt service from Telescopes Canada. One of the benefits of ordering here is they stock a good variety of products so if something happens your downtime is mitigated.
