Comet C/2023 A3 Tsuchinshan-ATLAS: new images – 28 Oct. 2024
At last, we imaged comet C/2023 A3 Tsuchinshan-ATLAS under good sky conditions, enjoying its features at different image scales and resolutions. Here we present the first two images we released.
C/2023 A3 Tsuchinshan-ATLAS, brightest region: 28 Oct. 2024.
The image above comes from the sigma clipping combination of 5, 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. The telescope tracked at the motion rates of the comet.
The ion tail is clearly visible with its typical structure. On the bottom, W of the pseudo nucleus, what is left of the antitail is visible as a faint, broad fan, developing on the E side of the comet.
We also managed to better investigate the inner coma, by sigma clipping combining 11, 30-second exposure, remotely taken with the “Elena” (PlaneWave 17″ + Paramount MEII + SBIG STL-6303E) robotic unit part of our facility.
C/2023 A3 Tsuchinshan-ATLAS, close up: 28 Oct. 2024.
The resulting image was carefully processed to extract the subtle features in the inner coma. Close to the central condensation, dest waves are visible, even if much less evident than in past images.
We will present more images from this observing session in a future release.
