8.2-m main mirror in its cell

KUEYEN Start-Up: Reinstallation of the Mirrors

The main mirror in its cell is lifted towards the lower part of the telescope structure to which it will next be bolted. (Photo obtained on 18 March 2000).

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 so called 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.
