The New Technology Telescope or NTT is an Alt-Az, 3.58-metre Ritchey–Chrétien telescope part of the European Southern Observatory and began operations in 1989. It is located in Chile at the La Silla Observatory and was an early pioneer in the use of active optics. The telescope and its enclosure developed a revolutionary design for optimal image quality.
Currently, the NTT is equipped with 2 instruments:
- SofI ("Son of ISAAC", a VLT instrument), a near infrared camera and low-resolution spectrograph, with polarimetric and high-time resolution modes
- EFOSC2 (ESO Faint Object Spectrograph and Camera, v.2), a visible light camera and low-resolution spectrograph, with multi-object spectroscopy, polarimetry and coronography modes
