Comet C/2023 A3 Tsuchinshan-ATLAS: new image – 25 Apr. 2025
We imaged comet C/2023 A3 Tsuchinshan-ATLAS again, four months after our previous observation: please find our picture here. The image above comes from the sigma clipping combination of 6, 120-second exposures, remotely taken with...
Comet C/2023 H5 Lemmon: a new image – 24 Apr. 2025
Here it is comet C/2023 H5 Lemmon, while it was crossing a nice spot in the sky, with galaxy NGC 3394. The image above comes from the sigma-clipping combination of 7, 30-second exposures, remotely...
Comet C/2025 F2 SWAN: a new image – 22 Apr. 2025
We imaged comet C/2025 F2 SWAN, despite the extreme (very low altitude, bright twilight) viewing conditions, after its likely disintegration. Here we present our picture. The image above comes from the average of 8,...
Comet C/2025 F2 SWAN (aka “SWAN25F”): a new image – 11 Apr. 2025
We imaged again comet C/2025 F2 SWAN, despite the full Moon and the bright sky at dawn, after it faded a bit since our previous observing session. Here we present our picture. The image...
Comet C/2025 F2 SWAN (aka “SWAN25F”): an image – 8 Apr. 2025
At the beginning of this month, a comet was discovered in the field of view of the SWAN instrument aboard the Esa/Nasa SOHO spacecraft. Temporarily named “SWAN25F”, then officially C/2025 F2 SWAN, it is...
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. The image...
Christmas with the Comet: online observation of C/2023 A3 Tsuchinshan-ATLAS – 23 Dec. 2024
After putting on a stunning show, comet C/2023 A3 Tsuchinshan-ATLAS is now a fond memory. We will look at it for Christmas, sharing images in real-time! We had a great time with this comet,...
Comet C/2023 A3 Tsuchinshan-ATLAS: new image – 30 Nov. 2024
Comet C/2023 A3 Tsuchinshan-ATLAS is constantly fading and now it is getting harder to spot, because of the dense Milky Way on the background. The image above comes from the sigma clipping combination of...
Potentially Hazardous Asteroid 2020 XR close encounter: an image – 30 Nov. 2024.
We release a new image of the Potentially Hazardous Asteroid 2020 XR, ready to have a close, but obviously safe encounter with the Earth next 4 Dec., coming as close as 2.2 millions of...
Comet C/2023 A3 Tsuchinshan-ATLAS: close-up and large view – 24 Nov. 2024
We release a couple of images of comet C/2023 A3 Tsuchinshan-ATLAS, now on its journey to the outer space, showing both the inner coma and the stunning spot of the sky the comet is...
Comet C/2023 A3 Tsuchinshan-ATLAS: new image – 24 Nov. 2024
We continue our follow-up observation of comet C/2023 A3 Tsuchinshan-ATLAS, constantly fading but still offering a remarkable view. The image above comes from the sigma clipping combination of 5, 120-second exposures, remotely taken with...
Comet C/2023 A3 Tsuchinshan-ATLAS: large field of view image – 19 Nov. 2024
We captured a new large field-of-view image of comet C/2023 A3 Tsuchinshan-ATLAS under very dark skies conditions. The image above comes from the average combination of 11, 120-second exposures, remotely taken with the Samyang 135+Paramount ME+ZWO...
Comet C/2023 A3 Tsuchinshan-ATLAS: new large field of view image – 13 Nov. 2024
We present an image of comet C/2023 A3 Tsuchinshan-ATLAS taken with an almost full Moon, using our large field-of-view astrograph. The image above comes from the average combination of 10, 120-second exposures, remotely taken...
