C/2023 A3 Komet Tsuchinsan-atlas
About this celestial object
Comet C/2023 A3 shows a delicate coma—a fleeting visitor, caught just above the horizon.
C/2023 A3 (Tsuchinshan–ATLAS) is a long‑period comet; its coma and tail often change appearance within days.
At 250 mm f/5 the object stays compact in the frame; in 19 minutes total, the diffuse envelope already emerges.
Captured near 12° elevation and 71% humidity—conditions that can mute contrast and tail detail.
