The photographer sent in this description with his image: In the foreground at both edges of the image stands the MAGIC Telescope I and II (Major Atmospheric Gamma-ray Imaging Cherenkov Telescopes). MAGIC-II is located at a distance of 85 meters from the first MAGIC telescope (at right). The stereo operation of both telescopes has increased the sensitivity of the observatory by a factor of ~3. MAGIC is not only huge (it was the largest telescope mirror in the world, with 17 meters in diameter, before the construction of H.E.S.S.) but also pioneers a number of technical developments that had never been applied to Cherenkov telescopes before. The mirror is extremely light and can be moved to any position in the sky in less than 30 seconds. It is made up of 270 individual mirror panels that can be independently focused using an active mirror control system equipped with lasers.

Between the giant Cherenkov Telescopes stands the mountaintop of the Roque de los Muchachos, where is placed from right to left, telescopes like Gran Telescopio Canarias (GTC), with a 10.4m primary mirror reflecting telescope (first silhouette), Telescopio Nazionale Galileo (TNG), that is a 3.6m alt-azimuth telescope with a Ritchey-Chrétien optical configuration, Nordic Optical Telescope (NOT) a modern 2.6m optical/infrared telescope, Dutch Open Telescope (DOT) an innovative optical telescope with a primary mirror of 0.45m diameter, for high-resolution imaging of the solar atmosphere, Swedish 1m Solar Telescope is the largest solar telescope in Europe and number one in the world when it comes to high spatial resolution, and finally the great William Herschel Telescope, the largest optical telescope of its kind in Europe, with a primary mirror of 4.2m in diameter, is one of the most scientifically productive telescopes in the world.
