Starpark, also known as Chilgapsan Astronomical Observatory, is nestled within Chilgapsan Provincial Park in Cheongyang-gun, Chungcheongnam-do. This observatory is a science museum with a focus on astronomy and space, catering to both the general public and students. Conveniently, it's just a five-minute walk from the parking area. The facility is housed in a three-story structure. On the first floor, visitors can enjoy a three-dimensional dome theater and an audiovisual room. The second floor houses a publicity center and an observation deck. The observatory’s main observation room is on the third floor and features Korea’s largest refracting telescope (APO 304 mm), which is used primarily for viewing sunspots and prominences during the day. Additionally, there’s an auxiliary observation room equipped with Korea's first 180-degree hemispherical three-stage sliding system. This room is designed for nighttime stargazing and is fitted with a 400-milimeter reflecting telescope for observing planets, star clusters, and nebulae. Children are particularly fond of the 12-meter geo-massive astronomical projection room, where they can experience 5D images. For those wishing to extend their visit, accommodations are available at Namcheon-ri Sanchon Ecological Village or nearby Alps Village. Staying in these locations provides easy access to both the Chilgapsan Astronomical Observatory and the Cheonjangho Suspension Bridge, making for a comprehensive educational and recreational experience.
