Anelli da guida 50mm

These high-quality pipe clamps are attached to a prism rail that can be inserted into the bracket of the William Optics telescopes. This ensures quick assembly with a secure hold. The clamps are lined with a felt to protect the 50mm finder / guide tube.

It is not a guide tube clamp in the classic sense, since the guide tube is not movable in this holder. Since the recommended guide tube from William Optics has a 5.7 ° field of view and should be used for relatively short focal length apochromats, this is also not necessary to find a guide star.
