Neutrino telescopes complement gamma ray telescopes in the observations of energetic astronomical sources as well as in searching for the dark matter. This paper gives the status of the current generation neutrino telescopes projects: Baikal, AMANDA, NESTOR, NEMO and ANTARES with particular emphasis on the ANTARES telescope in the Mediterranean Sea.

An active optics system for large UVOIR space telescopes
Paper 106986C, 7 S.The next generation of large monolithic mirror space telescopes will use aberration correction to ensure resolution performance is maintained throughout their mission. This is due to the use of ever thinner and lighter primary mirrors,

Grinding metre scale mirror segments for the E-ELT ground based telescope [PDF]
The next generation of ground based telescopes require many hundreds of metre scale off-axis mirrors. In this paper the grinding of a 1.45m scale Zerodur® mirror segment for the European Extremely Large Telescope (E-ELT) is introduced.

Optimized background suppression in near field lidar telescopes [PDF]
It is shown that a tilted slit in the focal plane of the lidar telescope limits the telescopes field of view efficiently and suppresses the background in the lidar signal by up to an order of magnitude better than a circular ...

The burst observer and optical transient exploring system in the multi-messenger astronomy era
The Burst Observer and Optical Transient Exploring System (BOOTES) was first designed as an asset of autonomous telescopes that started to be deployed in 1998, taking 24 years to be fully developed around the earth.

The LATT way towards large active primaries for space telescopes [PDF]
The Large Aperture Telescope Technology (LATT) goes beyond the current paradigm of future space telescopes, based on a deformable mirror in the pupil relay. Through the LATT project we demonstrated the concept of a low-weight active primary mirror, whose
