12P/Pons-Brooks 2024-Feb-03 Gianluca Masi
The image above comes from the sigma clipping combination of 25, 120-second unfiltered exposures, taken with the ARTEC250+Paramount ME+C3Pro61000EC robotic unit available as part of the Virtual Telescope Project facility in Manciano, Italy. A nice, faint tail is visible, spanning for more than 1.5 degrees.
At the time of our image, the comet was just undergoing a new, small outburst.
