The Isaac Newton Group of Telescopes (ING) consists of the 4.2-metre
William Herschel Telescope (WHT), the 2.5-metre Isaac Newton Telescope (INT)
and the 1.0-metre Jacobus Kapteyn Telescope (JKT). The ING is located 2350 metres
above sea level at the Roque de Los Muchachos Observatory (ORM) on the island
of La Palma, Canary Islands, Spain. The WHT is the largest telescope of its
kind in Western Europe.
The construction, operation, and development of the ING telescopes is the result
of a collaboration between the United Kingdom, The Netherlands and Spain. The
site is provided by Spain, and in return Spanish astronomers receive 20 per
cent of the observing time on the telescopes. The operation of the site is overseen
by an International Scientific Committee, or Comité Científico
Internacional (CCI).
A further 75 per cent of the observing time is shared by the United Kingdom,
the Netherlands and the Spanish Instituto de Astrofísica de Canarias.
The remaining 5 per cent is reserved for large scientific projects to promote
international collaboration between institutions of the CCI member countries.
The ING operates the telescopes on behalf of the Particle Physics and Astronomy
Research Council (PPARC) of the United Kingdom, the Nederlandse Organisatie
voor Wetenschappelijk Onderzoek (NWO) of The Netherlands and the Instituto de
Astrofísica de Canarias (IAC) of Spain. The Roque de Los Muchachos Observatory,
which is the principal European northern hemisphere observatory, is operated
by the IAC.
