The Isaac Newton Group of Telescopes (ING) consists of
the 4.2m William Herschel Telescope (WHT), the 2.5m Isaac Newton Telescope
(INT) and the 1.0m Jacobus Kapteyn Telescope (JKT), and is located 2,350m
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 and the Netherlands.
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 Instituto de Astrofísica de Canarias (IAC).
On the JKT the international collaboration embraces astronomers from Ireland.
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 IAC in Spain.
The Roque de Los Muchachos Observatory, which is the principal European Northern
hemisphere observatory, is operated by the IAC.
