Description:
Captured in the early hours of 30 November 2025, while the comet was still only about 23 degrees above the horizon, the view follows this true visitor from beyond the Solar System as it sweeps along a hyperbolic trajectory back into interstellar space. The image combines 30 one-minute RGB exposures obtained between 03:12 and 04:52 UT (04:12–05:52 CET). Tracking and registration were performed on the background stars; the final frame shows the appearance of 3I/ATLAS with respect to the star field at the time of the first exposure. The data were processed and photometrically calibrated to produce accurate RGB color while preserving the faint outer coma and surrounding star field.
