C/2023 A3 (Tsuchinshan-ATLAS) 2024-May-05 Gianluca Masi

The image above comes from the sigma-clipping combination of six, 300-second exposures, unfiltered and unguided, remotely taken with the Celestron C14+Paramount ME+SBIG ST8-XME robotic unit available as part of the Virtual Telescope Project. The telescope tracked at the motion rates of the comet. Very good sky conditions.
