First picture I've taken of C/2025 R2 (SWAN) that shows just a hint of a tail.

Evening comets:

Left: C/2025 A6 (Lemmon)
Right: C/2025 R2 (SWAN)

If I'm feeling ambitious I'll try to shoot Lemmon again in the morning if the clouds aren't too bad.

🔭 Earlier this evening, before the Moon rose, I spent about an hour tracking Comet C/2025 R2 (SWAN). Its brightness has now dropped to magnitude 8.4 and after rounding the Sun, the comet is heading back toward the distant regions beyond the Kuiper Belt.

Намагаюся насолодитися кожною секундою без хмар. Минулий вечір, знову C/2025 A6 (Lemmon) і C/2025 R2 (SWAN) з дещо збитим фокусуванням.

4/4. Una última mirada antes de que el C/2025 R2 (SWAN) continúe su viaje de 800 años de vuelta. 🌌

Destacamos una vez más la extensa coma. La estrella 51 Aql sirve como referencia para su posición en el cielo nocturno.

¡Hasta la próxima, cometa! 👋

Ніч з вівторка на середу була (нарешті!) безхмарною.
Тому, вдалося впіймати:
C/2025 A6 (Lemmon) - 1 - увечері 2 - ядро крупним планом, 3 - на світанку
і 4 - C/2025 R2 (SWAN).
Обидві були майже на піку яскравості.

Видно яскраве зелене ядро та короткий пиловий хвіст на темному фоні неба. Комета C/2025 A6 (Lemmon) на світанковому небі. Слабше світіння, але помітне зелене ядро й тьмяний хвіст серед розсипу зірок. Фото зоряного неба з кометою C/2025 R2 (SWAN). Комета виглядає як слабке зеленувате ядро серед зірок, без чітко видимого хвоста.

Good Wednesday evening. The weather cleared up so time to set the s50 outside. Starting out with #comet #c2025r2. #seestar #s50 #space #astronomy #amateur
Comet C-2025 R2 - telescope processed image with Moon and Skylight filter. C/2025 R2 (SWAN) is a long-period comet discovered in Sept. 2025. It reached perihelion on Sept. 12, 2025, and made its closest approach to Earth on Oct. 20, 2025. Best seen with binoculars. Comet C-2025 R2 - unprocessed image with Moon and Skylight Filter. Its orbit takes 22,000+ years, so it's a true once-in-a-lifetime sight! It was surprisingly bright and caught astronomers off-guard when discovered by the SWAN instrument.

2/4. Para entender lo que vemos, señalamos las partes principales del cometa: el núcleo (la bola de hielo), la coma (la atmósfera nebulosa) y la tenue cola.

Dato: Hemos añadido la silueta de la Luna 🌕 para que te hagas una idea del tamaño del campo que cubrimos.

#comet C/2025 R2 (SWAN) on Oct 27, aligned on the comet. Definitely faded a bit and not helped by some fog that came in during the shoot

(Canon G7 X, 210x5s, f/2.8 ISO 800 100mm EFL)

A patch of night sky, centered on the green fuzzy blob of the comet, surrounded by a scattering of colorful stars. The stars smeared diagonally due to the image being centered on the comet, and in the upper left of the more severely due to incomplete lens correction

#comet C/2025 R2 (SWAN) last night, same stack aligned stars and comet and processed similarly. Also M16, M17 and various other DSOs

(Canon G7 X, 210x5s, f/2.8 ISO 800 100mm EFL)

#astrophotography #Astrodon #c2025r2
Night sky, blue black in the upper right strewn with colorful bright stars, Milky Way to the left and below with countless stars fading into a reddish haze and darker clouds. Near the center, where the edge of the Milky Way starts to fade to black, is the green glowing blob of a comet, smeared diagonally between the upper left and lower right by its motion. Glowing red nebulae are visible above and below left of the comet, and several dense star clusters are scattered around the scene. The same scene, but the comet is now a perfect glowing orb and the stars are streaked diagonally. Closer crop of the star aligned image, centered on the comet.
