The European Solar Telescope (EST) (http://www.est-east.eu) is a European solar physics initiative involving more than 30 institutions from 18 countries, under the coordination of the IAC, representing the largest infrastructure of European research projected in the field of solar physics from Earth.

The IAC has long been aware of the importance of promoting initiatives for the characterization and protection of the Canarian Observatories (Roque de los Muchachos -ORM- on La Palma and Teide -OT- on Tenerife). For this reason, the Sky Quality Team was created and then a technical office for sky protection (OTPC) to ensure that the Law protecting

FP6 viability study proposal for a European Extremely Large Telescope. Contains studies and developments in various astrophysics-related fields: wavefront control, optics, mechanics, control, dome and infrastructure, adaptive optics, operations, instrumentation, and site characterisation.

Participation in OPTICON. One of the main goals of this project, to which many of the individual activities being carried out at OPTICON are also contributing, is to produce construction specifications for a European Extremely Large Telescope.

Una vez construido, el Telescopio de Treinta Metros (Thirty Meter Telescope, TMT) será el telescopio terrestre más avanzado y potente de la historia, así como el telescopio óptico infrarrojo más grande del hemisferio norte que existirá en ese momento. Se incluye entre los denominados de tipo Telescopio Extremadamente Grande por el diámetro de su
