Comet C/2023 A3 Tsuchinshan-ATLAS: new images – 22 Oct. 2024

Despite less than ideal sky conditions, we imaged comet C/2023 A3 Tsuchinshan-ATLAS with different telescopes and we share the results here.

C/2023 A3 Tsichinshan-ATLAS and its antitail: 22 Oct. 2024.

C/2023 A3 Tsichinshan-ATLAS and its antitail: 22 Oct. 2024.

The image above comes from the average combination of 5, 60-second exposures, remotely taken with the Samyang 135+Paramount ME+ZWO ASI 6200MC Pro robotic unit available as part of the Virtual Telescope Project facility in Manciano, Italy, under the darkest skies of the Italian peninsula. The telescope tracked at the motion rates of the comet. Sky conditions were far from being ideal, with plenty of thin clouds (see the haloes around the brightest stars), but we could capture an interesting image, also showing the antitail. The ordinary tail exceeds the field of view, so it is longer than 13 degrees.

We also imaged comet C/2023 A3 with our ARTEC250+Paramount ME+C3Pro61000EC robotic unit, allowing us to isolate the region around the nucleus. The image below comes from the average combination of 10, 30-second exposures: the result is satisfying, also showing an hint of the antitail and clear evidence of a ion tail.

We will continue monitoring this comet, despite the weather is not cooperating at all.
