Equipment: Sky-Watcher Quattro 150P, ZWO ASI585MC Pro

Integration: 1h 1m 44s

A capture of the infamous 3i/Atlas comet heading away from Earth on 20th December 2025. I wish I used a longer exposure to get the brighness up as the comet is barely visible - 8 seconds didn’t cut it this time - although you can barely make out the tail.
