The ESO New
Technology Telescope (NTT) is a 3.58m telescope which pioneered the use of active
optics. The telescope and its enclosure had a revolutionary design for optimal
image quality. Its current instrumentation consists of EMMI
(ESO Multi-Mode Instrument) for optical imaging in Blue or Red, low/medium/high
resolution spectroscopy, SuSI2
(Superb Seeing Imager - 2) for high resolution imaging and SofI
(Son of Isaac), the IR imager-spectrometer. The NTT first light happened
in 1989. In 1997, the telescope has been completely upgraded. The new system is
in fact almost identical to that to be used on the Unit Telescopes of the VLT.
In addition, new control software was written according to VLT standards for TCS,
EMMI, SUSI2 and SOFI. It now works at its best, producing top quality data in
a very reliable way: indeed, its down time is consistently less than 2% of the
available time. |
