12P/Pons-Brooks 2024-Mar-12 Gianluca Masi

The image above comes from the sigma clipping combination of 7, 120-second unfiltered exposures, unguided, taken with the ARTEC250+Paramount ME+C3Pro61000EC robotic unit available as part of the Virtual Telescope Project facility in Manciano, Italy. The telescope tracked the comet during the imaging session. The resulting image was carefully processed to preserve the finest details along the tail.
