Comet C/2023 A3 Tsuchinshan-ATLAS: new image – 17 Dec. 2024
While it is fading and leaving the inner Solar System, we imaged comet C/2023 A3 Tsuchinshan-ATLAS again, now that the dense Milky Way on the background is making it harder to see.
C/2023 A3 Tsuchinshan-ATLAS: 17 Dec. 2024.
The image above comes from the sigma clipping combination of 6, 120-second exposures, remotely taken with the ARTEC250+Paramount ME+C3Pro61000EC robotic unit available as part of the Virtual Telescope Project facility in Manciano, Italy, under the darkest skies of the Italian peninsula (SQM=21.5). The telescope tracked at the motion rates of the comet, which was less than 20 deg. above the western horizon.
Comet C/2023 A3 Tsuchinshan-ATLAS is just a pale of the show we enjoyed a couple of months ago. Nonetheless, it is a rewarding sight, with its diffuse coma against so many stars.
We will continue monitoring C/2023 A3 Tsuchinshan-ATLAS as long as possible.
