ASA AZ1500, AZ800 and ASA600 at the Atacama Desert, Chile
Four domes and three new telescopes was placed at the Observatory Cerro Armazones (OCA) in the Atacama Desert, Chile. OCA is ready for high-impact scientific observations.
- ASA600, an 0.6-m telescope,
- AZ800, an 0.8-m telescope and
- AZ1500, a1.5-m telescope
Our ASA team showed all their skills. Not only domes and telescopes were set up, but also all the ancillary work such as foundations, laying cable channels, etc. was done brilliantly by the ASA team.
