2023年10月至2025年6月姚安高精度望远镜海王星卫星观测图像

该图像数据来源于中国科学院紫金山天文台姚安天文观测站，使用配备高灵敏CCD相机的80厘米姚安高精度望远镜，在2023年10月至2025年6月间连续开展海王星卫星系统的长期观测任务。数据的生产过程包括原始图像采集、天文图像预处理（如平场校正、暗场校正、星像配准）过程。该数据集内容丰富，覆盖多个观测季节和不同位相下的海王星卫星系统，能够支持对天体运动与特性等科学问题的深入研究。其科学意义在于为改进现代行星历表中天然卫星轨道。在应用层面，这些图像可广泛服务于天体力学研究、历表产品更新、教学展示与公众科学传播等多个领域，具有重要的学术价值与应用前景。This image dataset originates from the Yao'an Astronomical Observatory of the Purple Mountain Observatory, Chinese Academy of Sciences. Long-term observations of the Neptune satellite system were continuously conducted using the 80cm Yao'an high-precision telescope equipped with a highly sensitive CCD camera from October 2023 to June 2025. The data production process includes raw image acquisition and astronomical image preprocessing steps such as flat field correction, dark field correction, and stellar image registration. This dataset is comprehensive, covering the Neptune satellite system across multiple observation seasons and different orbital phases, enabling in-depth research on scientific issues including celestial motion and its characteristics. Its scientific significance lies in providing support for improving the orbits of natural satellites in modern planetary ephemerides. In practical applications, these images can serve a wide range of fields such as celestial mechanics research, ephemeris product updates, teaching demonstrations, and public science communication, holding significant academic value and application prospects.
