Following the��coating of the 8.2-m main mirror of KUEYEN, the mirror in its cell was returned to the telescope enclosure.

Here it was remounted on the telescope structure in a series of operations that involved, among others, the installation of the socalled��M3-tower��in the central hole in the mirror. This structure supports the tertiary mirror (M3) that deflects the light towards the Nasmyth foci on the sides of the telescope.
