A mini ELT dome?

This drone image from October 2023, taken on the summit of Cerro Armazones, where ESO’s Extremely Large Telescope (ELT) is under construction, almost looks like a second, miniature ELT dome is being constructed. This device is an azimuth cable wrap, ensuring that the extensive network of cables helping to operate the telescope moves smoothly when the telescope rotates horizontally. This cable wrap has already been installed on top of the telescope pier.
