Comet C/2026 C1 (Tsuchinshan) remained near mag. 18 before disappearing into solar conjunction. It was still essentially stellar, with its tiny coma below my system's resolution. My last image until November, when it should be slightly brighter. #astronomy #comet ℹ️ cometografia.es/2026c1-tsuch...

Comet 220P/McNaught faded to about mag. 12 just three weeks after its remarkable outburst. A faint greenish coma, an elongated central condensation and a short dust tail remained, while later images showed no clear evidence of major fragmentation. #astronomy #comet ℹ️ cometografia.es/220p-mcnaugh...

Comet 10P/Tempel days ago, brightened to mag. 10, with its green fan-shaped coma continuing to expand as activity increased. A faint dust tail extends from the coma, while the distant galaxy pair IC 1331 and PGC 65391 adds an unexpected backdrop. #astronomy #comet ℹ️ cometografia.es/10p-tempel-2...

Periodic Comet 10P/Tempel as imaged on June 14. It had brightened to about mag. 11 while retaining a diffuse green fan-shaped coma around a well-defined false nucleus. IC 1324 and the edge-on galaxy PGC 65019 shared the rich background field. #astronomy #comet ℹ️ cometografia.es/10p-tempel-2...

C/2026 C1 (Tsuchinshan) remains stellar at 9 AU from the Sun, with no detectable activity in this follow-up image. Faint background galaxies are scattered across the field, highlighting how distant it is. Still fading into the evening twilight. #astronomy #comet ℹ️ cometografia.es/2026c1-tsuch...

Comet 220P/McNaught on June 8, about a week after its major outburst. Despite fading to around mag. 11, it still showed a broad green coma, a bright central condensation and a dust tail with a distinct central spine. #astronomy #comet ℹ️ cometografia.es/220p-mcnaugh...

C/2025 R3 (PANSTARRS) on May 19. This wider-field image revealed far more of the comet than my close-up view: a vivid bluish-green coma, a short dust tail, and a remarkably sinuous ion tail stretching about 6.5° through rich galactic nebulosity. #astronomy #comet ℹ️ cometografia.es/2025r3-panst...

Comet 88P/Howell remains near mag. 11 despite receding from the Sun. Its bright emerald-green coma is still prominent, while the tail has grown markedly over the past month, now reaching about 0.5°. The orange star pair makes a striking contrast. #astronomy #comet ℹ️ cometografia.es/88p-howell-2...

☄️ Comet 10P/Tempel is now around mag. 12 and its activity keeps increasing. It shows a broad green fan-shaped coma, standing out against a rich Milky Way star field ✨ One of the most interesting comets to follow over the coming weeks 🔭 #astronomy #comet ℹ️ cometografia.es/10p-tempel-2...

☄️June update 💥 220P/McNaught has been added to the guide after the spectacular outburst that boosted it from mag. 17.5 to about 8.5. Includes recent evolution, forecast and observing conditions 🔭 cometografia.es/cometas-visi... #astronomy #comet

Comet C/2025 R3 (PANSTARRS) is fading now, but on May it still showed a striking green coma, a long ion tail extending beyond the frame, and a rapidly evolving double plasma knot. The broad post-perihelion dust tail added a nice contrast to scene. #astronomy #comet ℹ️ cometografia.es/2025r3-panst...

My first image of periodic comet 10P/Tempel during its 2026 return. Still tiny, it shows a small green coma against a crowded Milky Way star field. I included globular cluster Palomar 11, pairing a fleeting visitor with an ancient Galactic resident #astronomy #comet ℹ️ cometografia.es/10p-tempel-2...

Comet C/2026 C1 (Tsuchinshan) around mag. 18 slowly brightening while remaining morphologically unchanged since April. Its tiny, highly condensed coma appears almost stellar, captured here in conjunction with galaxy UGC 07239 in the Virgo Cluster. ℹ️ cometografia.es/2026c1-tsuch... #astronomy #comet

Comet C/2026 C1 (Tsuchinshan) at mag. 18, showed a slightly brighter and condensed in this my second follow-up image. Remains nearly stellar in appearance while crossing the rich galaxy fields of Virgo, close to the barred spiral galaxy NGC 4334 🌀 ℹ️ cometografia.es/2026c1-tsuch... #astronomy #comet

Yesterday I was only able to obtain a single image of comet C/2025 R3 (PANSTARRS) from the Chilean Andes. Even with just a quick processing, it was enough to confirm that the comet remains very active, revealing notable structures in its tail. Hopefully there will be better luck next night.

☄️ New comet C/2026 C1 (Tsuchinshan) at mag. 19, still beyond Saturn’s orbit 🪐 After stacking one hour of exposure, appears as a tiny diffuse condensation lost among Virgo’s stars. Hard to imagine this faint object could become notable in 2028 🔭 ℹ️ cometografia.es/2026c1-tsuch... #astronomy #comet

☄️ Periodic comet 24P/Schaumasse was still shining near mag. 12 as it slowly receded from the inner Solar System. Its small green coma and faint tail remained visible against a rich star field in Serpens Caput, dotted with tiny background galaxies. ℹ️ cometografia.es/24p-schaumas... #astronomy #comet

☄️ C/2025 R3 (PANSTARRS) at its best from latitudes below 30°N. Now around mag 5.5, the comet remains accessible with binoculars after dusk. Dark moonless evenings provide excellent conditions to follow the evolution of its striking ion tail. ℹ️ cometografia.es/cometas-visi... #astronomy #comet

Comet C/2024 E1 (Wierzchos) on March 13, already showed obvious signs of disintegration: a very diffuse greenish coma, an almost collapsed central condensation and delicate 15' curved dust tail. By late March it had faded into a shapeless remnant. ℹ️ cometografia.es/2024e1-wierz... #astronomy #comet

☄️Comets in May 🔹C/2025 R3 (PANSTARRS) will be the standout: with binoculars early in the month (mag 4.5) with a very active ion tail ⚡ 🔹88P/Howell, second brightest around mag 10.5, observable with small telescopes 🔭 ⚠️Both comets only from latitudes below 30°N. ℹ️ cometografia.es/cometas-visi...

Comet 88P/Howell is currently around mag. 10, showing a green coma with a smooth brightness gradient and a nearly stellar condensation, plus a faint diffuse dust tail extending 4′. A quiet return, but well worth a closer look for patient observers🔭 ℹ️ cometografia.es/88p-howell-2... #astronomy #comet

Botched blackout, plot twist: stunning dark skies… and there I was, torn between awe and guilt, thinking, “easy there, Saint John—let’s not turn the lights back on just yet.” #astronomy #DarkSkies #blackout

Comet C/2025 R3 PANSTARRS in its farewell from northern hemisphere some days ago, showing finely structured ion tail with multiple filaments streaming away from its coma. Imaged very low in brightening dawn skies just before it was lost in twilight ℹ️ cometografia.es/2025r3-panst... #astronomy #comet

Comet C/2025 R3 (PANSTARRS) a week ago, imaged very low in bright twilight, yet showing a striking >4° ion tail with fine structure. A clear disconnection event is visible, with detached plasma drifting behind the head—solar wind in action. ☄️ ℹ️ cometografia.es/2025r3-panst... #astronomy #comet

Last days to observe comet C/2025 R3 (PANSTARRS) from the Northern Hemisphere, as it drops rapidly into the dawn sky on its way toward the Sun. Although the Moon will be gone, the comet will sink deeper into twilight with each passing day.

Comet C/2025 R3 (PANSTARRS) one week ago at mag. 6 Ion tail extending well over 1°, showing streamers and a narrow, slightly twisting main feature. Imaged at just 15° altitude under a Full Moon—conditions that make this result especially rewarding. ℹ️ cometografia.es/2025r3-panst... #astronomy #comet

Comet C/2025 R3 (PANSTARRS), Mar 23, was clearly improving: already at mag. 7.6, with an ion tail reaching ~1° and starting to reveal structure. Only 15° above the horizon and under poorer sky conditions… definitely an interesting target ☄️✨ ℹ️ cometografia.es/2025r3-panst... #astronomy #comet
