The standard mounting plate is mainly used to mount an optical tube or a lens, while allowing for micrometric rotation of 90° (on the axis corresponding to declination). The hardness of the rotation is adjusted using a brake and the micrometric movement is controlled by a knurled screw.

The micrometric plate, equipped with a Kodak thread (1/4"-20), is removable. It releases a dovetail equipped with 2 screws with Congress thread (3/8"-16) at each end, allowing the attachment of 2 independent photo ball heads, or one ball head and one optical tube.

It is entirely possible to use the micrometric plate on one side and a classic ball head on the other side. The dovetail, the micrometric plate, and the 2 Congress thread screws offer a great diversity of mounts to adapt to all your needs.
