In addition to Lemmon we have another bright comet at its peak of magnitude 6, visible with binoculars from anywhere in the world
This is C/2025 R2 (SWAN), and here’s its light curve. Observable without moonlight (blue band) at the beginning of the night:

📸🔭 October promises to be spectacular for comets:
☄️ C/2025 A6 (Lemmon) will reach magnitude 3–2 and be visible to the naked eye in dark skies.
☄️ C/2025 R2 (SWAN) will shine in binoculars, with long ion tails in photos.
We’ll keep following them day by day on these feeds so you don’t miss the show ✨

📸Comet C/2025 K1 (ATLAS) from Atacama a few days ago 🔭 just before becoming unobservable due to solar conjunction ☄️🌞
With a nice turquoise coma and two tails. If it survives, it will be visible again from the northern hemisphere at the end of October 🐻‍❄️

On September 11, I imaged Comet C/2025 K1 (ATLAS) from Atacama, Chile, just a few days before it became unobservable due to its conjunction with the Sun. In the image, it shows a brightness of magnitude 11 and a turquoise coma in good shape, condensed and about 3 arcminutes in size. The tail extends some 23 arcminutes, with an ionic central spine and what appears to be a faint dust tail opening at a narrow angle slightly above. The comet will become observable again in late October from the Northern Hemisphere, though it is uncertain whether it will survive perihelion.

☄️Comet C/2025 A6 (Lemmon) could be the brightest in a year, reaching mag 2 🔭👀
Here’s its light curve, with moonless nights in blue. After Nov 12 (red), it won’t be observable.
From the Southern Hemisphere below 20°S, it won’t be visible this apparition.

This morning I had a celestial inspiration — remember the misframed shots I took the day before? What if... they could be used to build a synthetic flat...? 🤔

I’ve got the L and RGB masters ready from yesterday’s shots of comet #SWAN25B. Let’s see what I can do with all those donuts 🍩 caused by overexposure 🌄 that the flats 💡 can’t fix. As for the scratches, let’s not even mention them — that’ll be half an hour of work courtesy of Eloncio.

🚨 New bright comet SWAN25B ☄️ at mag 7.4 with a >1.7° ion tail! In Virgo, visible after sunset from the Southern Hemisphere 🌍 (very hard from the North). Orbit still uncertain. Imaged it from Atacama—coma slipped out 😅 but the huge tail is clear. Tomorrow I’ll try again 🔭 and share more! 😉

📸 In the early hours of August 30 I captured my first image of comet C/2025 A6 (Lemmon) ☄️
It shows surprising activity: magnitude 11 with a striking green coma.
Excited to keep observing its evolution in the coming days 🔭

And here is the interstellar comet 3I/ATLAS that I captured last week from home.
I was only able to stack 7 frames so that the nearby star wouldn’t interfere and to be able to measure the comet’s brightness.
At magnitude 15.4 with a coma of 0.6 arcminutes
