The ESO New Technology Telescope
The ESO New Technology Telescope (NTT) is an Alt-Az, 3.58m Richey-Chretien telescope which pioneered the use of active optics. The telescope and its enclosure had a revolutionary design for optimal image quality.
The ESO New Technology Telescope, NTT, was commissioned in 1989, and completely upgraded in 1997 (Big Bang). It has an alt-az mounting, and two Nasmyth focii, which host two instruments. SUSI2 is mounted on Nasmyth A, while since 21 June 2008 EFOSC2 is mounted on Nasmyth B. The pointing error is about 1.5" RMS, but degradation occurs close to zenith and at zenith angle larger than 60 degrees. The pointing is limited to 70deg. zenithal distance, and 3 degrees from zenith.
Call for Ideas for the NTT
Published: 27 Feb 2014
This call opens new opportunities for large scientific projects at the NTT. In order to enable telescope access for innovative ideas, upgraded or new scientific instruments, up to 50% of the telescope time from 2016 to 2020 will be made available to selected projects in return for contributions to the NTT operation.
For the first phase of the definition of these projects, ESO is requesting ideas for scientific projects to be submitted no later than 31 March 2014. For details see the full text of the Call in PDF.
