Interstellar #comet #3I/ATLAS in the early hours of November 20 as seen from Crete, as the weather was favorable. A faint ion tail and anti-tail can be seen as the comet is past perihelion. Nothing out of the ordinary but cool to see such a bright interstellar object. #cometWatch
A green comet in front of star trails. Towards the top right extends a faint tail and a short one towards the opposite direction. Equipment: GSO N203/800 with TS GPU cc. Unmodified Olympus E-PL5. 76x30s frames from B4 skies. Edited with DSS and SIRIL.

A new comet, C/2025 T1 (ATLAS), was discovered earlier in October and it has brightened rapidly in just two weeks. Now it is around mag 11, has a round coma 4' and a short tail. It is near M101, in Ursa Major. Perihelion is in about a month, at 1.11 AU. #cometWatch
A comet with green round coma and a short tail. Equipment: GSO N203/800 with TS GPU coma corrector, and unmodified Olympus E-PL5. 66x30s acquired around 1:45 UTC, 29 October 2025 from Crete. Edited with DSS and SIRIL, this is the comet stack, with the stars appearing as trails. North is up.

Against all odds, C/2025 K1 (ATLAS) has survived perihelion, which was at Mercury's orbit. The comet has emerged in the dawn sky and features a long ion tail, more than a degree long, with a distinct reddish color (contrary to the usual blue). #CometWatch
A comet with white coma, about 2' across, and a yellowish thin tail with extends beyond the edge of the frame. A faint dust tail is also visible. The image is stacked on the comet and the stars appear as trails. Equipment: GSO N203/800 with TS GPU CC, unmodified Olympus E-PL5, AZEQ5 62x30s ISO 1600 frames, acquired on 29 October 2025, around 3:20 UTC, from B4 skies of eastern Crete.

Comet Lemmon on 23 October, showing a very active and turbulent ion tail. Slightly different processing to not burn the nucleus. More info in alt. #cometWatch #astronomy #astrophotography #space
Comet Lemmon, showing the slightly curved and broad dust tail, the ion tail, with knots and disconnections, and the green coma is still visible. Samyang 135mm f/2 wide open, unmodified Olympus E-PL5. 23x15s+1x25s (total exposure time 6m10s), from Eastern Crete. Edited with DSS, GraXpert, and Ps.

Comet Lemmon is hands down the third best comet of the last 10 years for the northern hemisphere. As easy with the naked eye as the Andromeda Galaxy, with a hint of tail 2-3 degrees long from dark skies! Unfortunately clouds were present at the direction of the comet. #cometWatch #astronomy
Wide view of the starry sky but clouds are creeping in. The Corona Borealis is the most striking feature of that region of the sky. Below it, in between the clouds is visible comet Lemmon, with its tail. OM-5 camera with the Panasonic 20mm f/1.7 open at f/1.8 untracked. Single 10s image sooc.

Comet C/2025 R2 (SWAN) passing near the Eagle Nebula on 17 October 2025, around 18:30 UTC. Nice pair visually through 8x50 binoculars. The comet is near its closest approach to Earth, at a distance of 39 million km. #cometWatch #astrophotography #space
A green comet with round coma and faint thin tail is visible to the bottom left. The coma is 10-11' across and the tail 15-20' long. To the right is visible a pinkish nebula, known as the Eagle Nebula. The starry background also has dark nebulas and star clusters.

Back to comet C/2025 A6 (Lemmon) today before dawn. What a development in 10 days. The tail barely fits in the lovely Samyang 135mm lens FOV. Sunflower and Croc's Eye galaxies are visible too. #cometWatch #astrophotography
Comet C/2025 A6 (Lemmon) on the early hours of 17 October 2025 (around 3:00 UTC) crossing Canes Venatici, with the galaxies M94, M63 and NGC 5005 and 5033 visible. The ion tail extends beyond the edge of the frame with streamers and knots and the dust tail is also quite prominent, about 4° long and slightly curved. 55x25s, ISO 1600 frames, Samyang 135mm @f/2 and unmodified Olympus E-PL5.

A nice clear sky helped me photograph comet C/2025 A6 (Lemmon) on 1 October 2025. The ion tail is becoming brighter and full of streamers and the dust tail grows. #cometWatch #astrophotography
A comet with a tail among the stars. The green gasy coma is about 10 arcminutes across. The ion tail extends beyond the edge of the frame. Equipment: GSO N203/800 with TS GPU cc, AZ-EQ5, unmodified Olympus E-PL5. Exposure: 100x30s, from B4 skies of eastern Crete. Edited with DSS, SIRIL and GIMP.

Comet C/2025 R2 (SWAN) finally cleared the twilight zone from southern Europe (and the clear atmosphere certainly helped despite the presence of some clouds). Coma is about 6' and the ion tail is visible too in this 10min exposure. #cometWatch
Image of a comet among the stars. Image is stacked on comet so the stars appear as lines. The comet has an green coma and a faint ion tail.

Comet C/2025 A6 (Lemmon) today. Coma is 8' across, smaller than a few days before, but dust tail is becoming more prominent. Also brightenening seems to have stalled, yet the nucleus and coma look good. I'll keep an eye on it. 🧐 #cometWatch #astronomy

Comet C/2025 A6 (Lemmon) looked gorgegous on the early hours of September 24, as the ion tail became again quite prominent. #cometWatch #astrophotography #comet #space
Comet stack of comet C/2025 A6 (Lemmon) - the comet is static while the stars appear as trails. The ion tail appears to be bifurcate and there is also a faint dust tail. Photo taked with a GSO N203/800 telescope and an unmodifed Olympus E-PL5 camera. 103x30s frames. Edited with DSS and SIRIL.

Periodic comet 240P/NEAT on 23 September 2025. Much brighter than initial predictions, it features a dust tail which up to its faintest extremities is 25 arcminutes long. Currently slowing down as it enters retrograde motion. #cometWatch #astrophotography #astronomy
A small dusty comet (240P?NEAT) and a few stars. 23 September 2025, 2:15 UTC. GSO N203/800 telescope with coma corrector, unmodified Olympus E-PL5. 46x30s from eastern Crete, B4.5. Edited with DSS and SIRIL.

Lovely image of two comets one next to the other from the southern hemisphere. Mars was also nearby. #cometWatch

Actuellement deux comètes présentes dans notre système solaire semblent se tirer la bourre. Leur nom de code : C/2025 K1 ATLAS (à gauche) et C/2025 R2 SWAN (à droite). En réalité leurs trajectoires respectives sont très différentes.

Something different today. Comet 414P/STEREO is in the constellation of Leo, not far from Regulus and Venus, at an elogation of 29°. Perihelion is on 26/9. Small green coma, maybe a fain tail. #CometWatch

Comet C/2025 A6 (Lemmon) in the early hours of 16 September. Coma has grown to about 6-7 arcminutes, there is a faint ion tail about 20 arcminutes long and possibly a short ion tail has started growing. #cometWatch #astrophotography

Comet C/2025 A6 (Lemmon) on 6 September, before the Moon starts interfering fot the next two weeks. Mediocre to bad conditions due to high humidity. Nice green coma 4' and faint ion tail. Back again in about 10 days. #cometWatch #astrophotography

The inner coma is quite bright and there is also an outer coma about 6' across that can be visible with a relatively short exposure.

Comet C/2025 A6 (Lemmon) is much brighter than current predictions (maybe around mag 13) and even visible in the individual 20s frames today before dawn. Hopefully it will be a nice binocular object in autumn. #cometwatch

Small comet C/2025 K1 (ATLAS) at mag ~14 is the brightest comet in the sky right now. Tail is about 5' long. Currently in the constellation of Vulpecula, it approaches rapidly Earth next month. #cometwatch #astrophotography #comet
