I've been to several observatories around the world, but Purple Mountain Observatory stands out for its exceptional services. The observatory offers a unique experience to explore the night sky. I was impressed by the knowledgeable staff who provided detailed explanations. The facilities were top-notch, and the telescopes provided a clear view of celestial objects. Highly recommended for astronomy enthusiasts!
