本系列精心打造的古代天文觀測儀器，以純銅材質呈現，涵蓋渾儀、簡儀、赤道經緯儀、地平經緯儀等經典款式。渾儀，古代重要的天文觀測工具，其結構復雜而精巧，通過多個同心圓環的組合，能夠測量天體的赤經、赤緯等坐標信息，為古代天文學家探索宇宙奧秘提供了有力支持。簡儀則是對渾儀的改進與簡化，去除了不必要的部件，在保持觀測精度的同時，提高了觀測效率，使天文觀測更加便捷。赤道經緯儀專為觀測赤道坐標而設計，其獨特的結構能夠精準地測量天體在赤道坐標系中的位置，對于研究天體的運動規律具有重要意義。地平經緯儀則側重于測量天體的地平坐標，通過水平和垂直兩個方向的測量，幫助觀測者確定天體在地平坐標系中的位置，廣泛應用于天文觀測和航海定位等領域。這些儀器采用純銅材質，不僅具有良好的耐久性，還賦予了它們獨特的藝術價值，無論是作為科學研究工具，還是作為裝飾品擺放在歷史室中，都能展現出古代天文學的魅力與智慧。

This series of ancient astronomical observation instruments, crafted from pure copper, includes classic models such as the Armillary Sphere, Simplified Instrument, Equatorial Coordinate Instrument, and Horizontal Coordinate Instrument. The Armillary Sphere, a significant ancient astronomical observation tool, features a complex yet exquisite structure. Composed of multiple concentric rings, it can measure the right ascension and declination coordinates of celestial bodies, providing strong support for ancient astronomers exploration of the mysteries of the universe. The Simplified Instrument is an improvement and simplification of the Armillary Sphere. By removing unnecessary components, it maintains observation accuracy while increasing efficiency, making astronomical observations more convenient. The Equatorial Coordinate Instrument is specifically designed for observing equatorial coordinates. Its unique structure can accurately measure the positions of celestial bodies in the equatorial coordinate system, which is of great significance for studying the laws of celestial motion. The Horizontal Coordinate Instrument focuses on measuring the horizontal coordinates of celestial bodies. By measuring in horizontal and vertical directions, it helps observers determine the positions of celestial bodies in the horizontal coordinate system and is widely used in astronomical observations and navigation. Made from pure copper, these instruments not only have good durability but also possess unique artistic value. Whether used as scientific research tools or displayed as decorations in a history room, they can showcase the charm and wisdom of ancient astronomy.
