My attempt at #CometLemmon in the early hours of Oct. 14th. The comet is brightening and rushing towards closest approach to Earth (Oct. 21st). It's getting low in the morning sky, though it will pass into evening sky for convenient viewing soon.

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.

Comet C/2025 A6 (Lemmon) is getting low into the dawn, and this is the first time I felt the need to process it. With the way the weather forecast is looking, this might have been my last chance to shoot it before it disappears in the Sun.

Extraordinary image of #comet #C2025A6 #Lemmon taken this morning from Observatori de Pujalt, l'Anoia, #Catalunya
Great expectations for having it next month as a naked eye object!
My outreach article gives clues on how observing it. Already it is noticeable using binoculars

El cometa Lemmon evoluciona muy positivamente para ser visible a simple vista y resulta espectacular con prismáticos al amanecer. (¡Foto de hoy mismo!) ❤️

🔭 Over the past few days, I’ve tried several times to capture comet C/2025 A6 (Lemmon) again.
Last night, I finally managed to do it! The conditions weren’t great and I couldn’t see it with the naked eye, but luckily I could spot it through my binoculars.

C/2025 A6 (Lemmon) from last night. I was able to stack 52 subs at 60 seconds each. I noticed that the comet’s nucleus can actually be seen by turning down the brightest areas just a touch. Check out the 2nd image for a closer look.
