New aluminization of the mirror of the Joan Oró telescope
19/07/2018
 
During last June, the astronomers and technical staff of the Montsec Astronomical Observatory (OAdM) carried out the dismantling of the primary mirror of the Joan Oró telescope.

The 80 cm mirror, weighing around 110 kg, was carried to the Calar Alto observatory in Almeria, we there is the necessary infrastructure for the cleaning of the mirror and the vacuum chamber for injecting of a new layer of aluminium.

The operation, one of the most delicate that is performed in the maintenance of the TJO, and which had been carried out for the last time in 2013, has been successfully completed and the OAdM astronomers could measure an increase in reflectivity of the mirror between 60 and 65% in the different filters available to the MEIA2 instrument.
