10月14日，很难捕捉到彗星C/2023 A3 Tsuchinshan-ATLAS的全貌。在这颗彗星最接近我们美丽的星球之后拍摄的这张傍晚的天空图几乎是这样。这张照片是两幅长焦相结合的，从上到下，从亚利桑那州图森市的盖茨山口向西望去，从上到下绵延约26度。那天晚上，彗星观测者甚至可以识别出球状星团M5和周期彗星13P奥尔伯斯的微弱幻影，这颗彗星位于明亮的彗星昏迷上方的巨心山-阿特拉斯的白色尘埃尾巴的长路径附近。由于地球正穿过彗星的轨道平面，所以“土山-阿特拉斯”也有明显的反尾巴。反彗尾是由先前释放的尘埃组成的，这些尘埃沿着彗星的轨道从太阳向外散开，在明亮的彗发下方，朝向崎岖的西方地平线，呈针状延伸。不断增长的画廊：2024年的土钦山彗星

On October 14 it was hard to capture a full view of Comet C/2023 A3 Tsuchinshan-ATLAS. Taken after the comet's closest approach to our fair planet, this evening skyview almost does though. With two telephoto frames combined, the image stretches about 26 degrees across the sky from top to bottom, looking west from Gates Pass, Tucson, Arizona. Comet watchers that night could even identify globular star cluster M5 and the faint apparition of periodic comet 13P Olbers near the long the path of Tsuchinshan-ATLAS's whitish dust tail above the bright comet's coma. Due to perspective as the Earth is crossing the comet's orbital plane, Tsuchinshan-ATLAS also has a pronounced antitail. The antitail is composed of dust previously released and fanning out away from the Sun along the comet's orbit, visible as a needle-like extension below the bright coma toward the rugged western horizon.
