Swan and Atlas on my agenda but, based on Stellarium simulation for my location in Northern Italy, best view in November for both of them.

Il Muso ha sbroccato come al solito, è stato asfaltato da un non imbattibile Aliassime, che per quanto in fiducia è stato a sua volta arato da Rinderknech, e i cinesi non gli hanno perdonato l'uscita infelice di Pechino. Continua a mancargli la testa per fare davvero un salto di qualità.

Oh @goffry.bsky.social, Shanghai sta diventando il torneo più interessante dell'anno. A questo punto non so se tifare per l'immortalità di Nole o per una finale pazzesca fra Rinderknech e il qualificato Vacherot, dopo che entrambi han fatto fuori quattro teste di serie (cinque, in caso di finale).

Ho sentito Giorgetti dire che nonostante abbiano abbassato le tasse non spendiamo perché vediamo la guerra in tv.

Ha detto proprio così.

E io che pensavo non fosse all’altezza dei suoi esimi colleghi di governo.

Just check out on IG with #lemmon hashtag, there are plenty of wonderful images much better than my one taken under stunning clear skies, but thank you a lot 🙂🙏🙏

En réalité, la qualité de l'image s'améliore avec le temps d'acquisition (et évidemment avec l'obscurité du ciel, ce qui n'est malheureusement pas favorable ici). Elle se trouve actuellement dans le Système solaire, presque au point le plus proche du Soleil sur son orbite. Merci!

no more than when I come back from a trip with thousands of photos and I have to choose which ones to publish 😃

To be honest I take my photos from the terrace of my home in an ordinary town in northern Italy and stars are almost invisible due to light pollution. Welcome in Bortle 8 conditions. So I’m not really missing out on anything in local sky and could not get anything without deep sky photo processing 🙂

That’s totally another sport. Basically satellites don’t care at all about Mr. Bortle when playing the game 🙂

I don't think I understand the question. What do you mean by satellite photography?

Hard to say, as it changes from night to night. This is a 600mm FL. I tracked with mount’s ordinary sidereal tracking rate, then I stacked separately the stars and the comet.

This is a double stack of 476×15", stars and comet processed separately due to their different apparent motion. I kept shots very short both to counter the comet’s motion relative to the FL used and the mount’s sidereal tracking rate, and to prevent the full Moon’s light from blowing out the tail.

476x15". I used very short exposures to counter both the comet’s motion and the very bright sky due the full moon light.

Because the full Moon’s light and the strong gradient from light pollution, etc., aren’t uniform, and they eat away part of the tail depending on the conditions, the calibration of the images, and the processing workflow.

I’ve read about this too, but the simulation in Stellarium shows a different scenario. Apart from the magnitude, at night it will be practically no longer visible, at least from my location. These are the last days when it’s possible to see it at night; by the new moon it will be very different.

The full moon light tends to swallow the tail completely. To limit these problems I kept the exposures very short, just 15 seconds, so I ended up with nearly two terabytes of data to deal with in post-processing.

The hardest problems come from the comet's speed different from the sky’s apparent motion, so you have to stack the stars separately from the comet, but the comet stack brings along star trails, a nightmare to remove. In this particular case I also had plenty of issues with the full Moon’s light.

Hardly the best photo among the endless ones flooding my Instagram feed these days, but given the conditions I’ll call it a win. If I can bring myself to get up at that ungodly hour again, maybe in a couple of weeks I’ll try again under a moonless sky.

Two nights of 3:45am alarms, blazing full moon lighting the sky like daytime and washing out the light of everything else, comet included. Then two days of post-processing battles, as comet processing is maddeningly tricky.

But I finally pulled it off: here is C/2025 A6 Lemmon. 🔭
