Chilgapsan Astronomical Observatory Star… | Attraction Guide

Chilgapsan Astronomical Observatory Star Park is located halfway up Chilgapsan, known as the ancestral mountain of Baekje. The name Chilgap comes from 'Chil (7),' the principle of the creation of the universe and all things, and 'Gap,' symbolizing the first in the sixty-gapja celestial cycle. Chilgapsan Astronomical Observatory, the only one situated within a provincial park in Korea, is an astronomy and space-themed science center where visitors can experience the clear night sky in the pristine nature of Cheongyang. It features Korea's largest refracting telescope with a full-dome 3D imaging system and various astronomy programs to feel the mystery of the universe. The observatory includes a planetarium, main observatory, auxiliary observatory, and audiovisual room. The planetarium projects a virtual sky identical to the real night sky onto a 10m dome screen, enabling astronomy education regardless of weather conditions. It offers high-resolution 3K Full Dome videos using a 5-channel laser projection system and space science videos with a 5.1-channel surround sound system. The main observatory, equipped with the country's largest 304mm refracting telescope for a public observatory, allows observation of planets, nebulae, and star clusters. The auxiliary observatory, designed with a hemispherical sliding dome surrounding the main observatory for the first time in Korea, houses various auxiliary telescopes of different types and apertures, also for observing celestial objects. On the first floor, the audiovisual room provides astronomy lectures focused on space science during events.
