A mountain observatory is a type of astronomical observatory located in a high altitude environment, typically on the summit of a mountain. The high altitude provides clearer and less turbulent views of the night sky, allowing for more precise and detailed observations of celestial objects. Mountain observatories are often equipped with advanced telescopes and instruments to study objects such as stars, galaxies, and other astronomical phenomena. They are used by astronomers and researchers to conduct a wide range of studies and observations in astronomy and astrophysics.
