This mechanical extension helps maintain a shorter overhang when using heavy photographic accessories. It is used, in particular, in the assembly of the FCT-65D field corrector.<\/p>\n<h3>Compatibility and Installation<\/h3>\n<p>The ring uses the Takahashi M55.9 thread with a pitch of 0.75 mm. Position it according to the diagram for the telescope and corrector.
