Comet Tsuchinshan-ATLAS and M5

[mreclipsen]

Comet Tsuchinshan-ATLAS( C/2023 A3 ) and the M5 Serpens Cluster in the same frame. The image was captured in 2024 using a Canon EOS 6D (infrared-modified) digital SLR camera paired with a 65mm APO. ISO3200, single exposure of 8 seconds, with a total of 180 frames stacked. In the limited shooting window, I used deep sky photography techniques to clearly capture the anti-tail of the comet, M5, and the surrounding stars. It turns out that the details of this comet are easier to capture with an infrared-sensitive camera.The window for capturing the comet and M5 in the same frame was very short, and before I could accumulate enough signal-to-noise ratio, they set below the horizon. This photo was taken at an altitude of 2,000 meters to obtain as much low-altitude exposure time as possible.
This moment marks the first time the comet has been photographed alongside a famous Messier object during its post-sunset observation period.
Taken on October 15, 2024, at Bingshanliang (altitude 2000m) in Zhangjiakou, Hebei Province, China.
