Dutch Open Telescope, Solar telescope at Roque de los Muchachos Observatory, La Palma, Spain.
The Dutch Open Telescope features a 0.45-meter mirror and operates at an elevation of 2350 meters for solar observation and research.
The telescope began operations in 1997 at La Palma, introducing an innovative open design that differed from traditional vacuum-style solar telescopes.
Scientists from multiple institutions collaborate at this facility to study solar phenomena, magnetic fields, and surface activities of the sun.
The telescope employs specialized filters and cameras to capture simultaneous images across different wavelengths, enabling detailed solar surface analysis.
Wind circulation around the mirror maintains constant temperature, while a polymer fiber roof system ensures structural stability during observations.
