Chinese astronomy enthusiast's 'chasing project'
90后追星“青年”为中国空间站拍“写真”
Liu Boyang, a post-1990 astrophysics doctor and astronomy enthusiast, took hundreds of thousands of photos of the China Space Station (CSS) with a self-developed automatic tracking script for optical recognition.
中国90后天体物理学博士、天文爱好者刘博洋用自主开发的光学识别自动跟踪脚本，拍摄了数十万张中国空间站的照片。
Common methods for shooting celestial bodies are not suitable for taking higher-precision photos of the space station.
常用的天体拍摄方法不适合拍摄更高精度的空间站照片。
Given some of the disadvantages of the current methods, Liu came up with his own plan – writing an automatic tracking script for optical recognition, then manually finding the space station and framing the tracking based on the control of proportional, integral and differential units.
考虑到现有方法的一些缺点，刘博洋提出了自己的方案——编写一个光学识别的自动跟踪脚本，然后手动找到空间站，并基于比例、积分和微分单元的控制框架跟踪。
It took a lot of trial and error before Liu finally fixed the bug and verified the function of the program this April.
经过大量的尝试和失败，他终于在今年4月修复了这个错误并验证了该程序的功能。
Starting in April, Liu and his team have been chasing the space station and recorded over 50 configuration changes from Beijing and South China's Hainan province. He captured the Tianzhou-3 cargo spacecraft's separation from its core module, the Shenzhou-14 spacecraft's launch, and the Mengtian Lab Module's docking with the core module, among others.
自从4月拍下中国空间站开始，刘博洋和团队半年来开启“逐天模式”。从天舟三号撤离空间站，到天舟四号、神舟十四号发射，再到问天舱、梦天舱对接成功，刘博洋一行人在北京、海南等多地，50余次追拍中国空间站特写影像并把这些构型变化完整记录下来。
When asked about his plan for the future, the 32-year-old astronomer said that he had been preparing himself to record the Tianzhou-5 cargo spacecraft and Shenzhou-15 spaceflight, and it would be his lifetime commitment to explore every possibility to show people the sky and help them learn about space and the universe.
当被问及他的未来计划时，这位32岁的天文学家说，目前他正在准备天舟五号货运飞船和神舟十五号载人飞船的跟拍计划，这将是他毕生的承诺，探索各种可能性，向人们展示天空，帮助他们了解空间和宇宙。
