Packaging Skinakas’ primary mirror
Back in November of 2019, the primary mirror (of 1.3m) at the Skinakas Observatory was dismounted to send it for recoating (a procedure performed once every 4-5 years). The following short clip shows the packaging of the mirror, a very delicate procedure (the whole process took several hours … compressed to a few minutes).
Cleaning the 3.5m mirror of NTT-ESO
That’s an impressive image of how to clean the main, 3.54m diameter, mirror of the New Technology Telescope (NTT) on La Silla. “This very delicate process is performed using a natural sponge, soft soap and distilled water”, as stated at ESO’s site.
