Iso-Heikkilä Observatory, Astronomical observatory and library in Iso-Heikkilä, Turku, Finland
Description
Iso-Heikkilä Observatory is a stargazing facility in Turku equipped with telescopes and astronomical equipment for observation work. The building features two 6-meter domes, with one housing a 15-centimeter refractor telescope positioned at approximately 20 meters in elevation.
History
The site was built in 1937 under Professor Yrjo Vaisala's direction and originally served the University of Turku's astronomy department. In 1972, it transitioned to amateur astronomers as urban growth made professional observations less practical.
Culture
The site functions as a gathering place for the Turun Ursa amateur astronomy association, where members and visitors share observations and discuss the night sky together. These gatherings have become part of how the local community engages with astronomy and the cosmos.
Practical
The facility is located at Pohjantähdentie 7 and operates primarily for members of the local astronomy community. Those interested in visiting should check availability in advance, as access is mainly restricted to association members.
Did you know?
Before transitioning to amateur use, researchers working here discovered 807 minor planets and seven comets. This remarkable output reflects the site's former importance as a center for professional astronomical discovery.
