Danish 0.5-metre telescope (decommissioned)
The Danish 0.5-metre telescope was installed at La Silla in 1971, together with its twin, the ESO 0.5-metre telescope. It was equipped with a revolutionary photometer that permitted simultaneous observations in all the filters of the Strömgren system. Moreover, the telescope was fully programmable, which made it a precursor of the later automatic telescopes.
