Encounter Within One Second ? Zhang Yanguang This image captures the International Space Station (ISS) transiting across the solar disc. The solar background was captured separately with double-stacked etalon[an optical filter that isolates specific wavelengths, used to observe solar details], and reveals high-contrast chromospheric details. The imaging sequences were strategically combined during post-processing to preserve both the spacecraft?s crisp silhouette and the Sun?s intricate surface features. Taken with a Takahashi Teegul 60 telescope, Coronado SolarMax 60 double stacked, Vixen polaris mount, Player One Astronomy Neptune-M camera, 500 mm f/8.3, 0.3-millisecond exposure Location: Xiamen, Fujian, China, 24 January 2025
