It is a modified form of a Cassegrain telescope Cassegrain telescope, mounted on an Altazimuth mount alt azimuth mount. Scheme As in the Cassegrain telescope, the light falls on a concave primary mirror, then goes into a convex secondary mirror. However there is no hole in the primary mirror. Instead a small flat mirror reflects the light to one of the sides of the telescope. This flat mirror is placed on the altitude axis, so that the exit beam comes out of a hole in the middle of the altitude bearing. This means the eyepiece or instrument does not need to move up and down with the telescope therefore a heavy instrument can be used without upsetting the balance of the telescope or increasing the load on the altitude bearings. This has significant advantages for spectrographs and other heavy instruments typically used at research observatories. Most modern research telescopes can be configured into a Nasmyth telescope i.e. to use the Nasmyth Focus . Observatories The Sierra Nevada Observatory OSN in Spain has 2 Nasmyth telescopes, including a 1.5 meter diameter aperture one.

It is named after Gerard Mercator , famous cartographer. The telescope contains two different measuring devices. First of all, there is the MeropeII CCD camera . This camera has a size of 2k by 6k pixel s Frame Transfer detector originally designed for ESA s canceled Eddington space mission. The filters used together with this camera are according to the so called geneva photometric system . The second instrument on the Mercator Telescope is the HERMES echelle spectrograph . It covers a wavelength range between 380 and 875 nanometer nm with a spectral resolution of R 85000 ref http www.mercator.iac.es instruments hermes RaskinHERMES.pdf ref . The P7 photometer was active from May 2001 until July 2008. The photometer measured in the 7 band Geneva photometric system. It measured the star in one channel and the sky in another so that the sky can be subtracted. The filter wheel is turning at a rate of 4 Hertz Hz , changing between the filters of the photometric system. It is sited at the Roque de los Muchachos Observatory Observatorio del Roque de Los Muchachos on La Palma . The Swiss Euler 1.2m Telescope and the Mercator Telescope were part of the Southern Sky extrasolar Planet search Programme which has discovered numerous extrasolar planets. ref http obswww.unige.ch udry planet coralie.html ref For other large telescopes of the period see List of largest optical telescopes in the 20th century .

A network telescope also known as a darknet , Internet motion sensor or black hole ref name ieee cite web url http ieeexplore.ieee.org xpls abs all.jsp?arnumber 1550875 title Defining and Evaluating Greynet s Sparse Darknets publisher ieeexplore.ieee.org accessdate 2008 06 24 ref is an Internet system that allows one to observe different large scale events taking place on the Internet. The basic idea is to observe traffic targeting the dark unused address space of the network. Since all traffic to these addresses is suspicious, one can gain information about possible network attacks random scanning worms, and DDoS Internet background noise Backscatter Noise backscatter as well as other misconfigurations by observing it. The resolution of the Internet telescope is dependent on the number of dark addresses it monitors. For example, a large Internet telescope that monitors traffic to 16,777,216 addresses a 8 Internet telescope in IPv4 , has a higher probability of observing a relatively small event than a smaller telescope that monitors 65,536 addresses a 16 Internet telescope . A variant of a network telescope is a sparse darknet, or greynet, consisting of a region of IP address space that is sparsely populated with darknet addresses interspersed with active or lit IP addresses. ref name ieee See also Honeypot computing External links http www.caida.org research security telescope CAIDA Network Telescope Research http www.simwood.com 2011 08 an introduction to the simwood darknet Simwood eSMS Darknet Project http www.team cymru.org Services darknets.html Team Cymru Darknet Project References Moore et al. http www.caida.org publications papers 2004 tr 2004 04 tr 2004 04.pdf Network Telescopes Technical Report , 2004 reflist Category Internet terminology compu network stub ... more details
