ULTRACAM on the 3.5m NTT


To date, ULTRACAM has been used for a total of 659 nights on the ESO 3.5m New Technology Telescope (NTT) at La Silla, Chile. It was first mounted on the NTT in 2015 at the "straight-through" position of the Nasmyth B focus. From 2019 to the present day, ULTRACAM has been permanently mounted at the "folded" position of the Nasmyth B focus, fed by a quaternary mirror (M4) in the instrument "cube".
