Comet A6 Lemmon on October 24 sent on October 28, 2025 (8:12) by Gianluca Galloni. 38 comments, 1918 views.  [editors pick] [retina]

Prima elaborazione di questa splendida cometa, non tanto per la luminosità quanto più per il dettaglio ripreso sulla coda di ioni. Ho effettuato questa ripresa Venerdì 24 Ottobre, più o meno dalle 19:15 alle 20:00 lottando purtroppo con le velature. La serata era davvero trasparente ma alcune nubi alte mi hanno fatto scartare circa il 60% dei frame. Questa quindi è la somma di sole 28 pose da 60s. Riprese direttamente dall'osservatorio di Mairago con Askar 103APO ridotto a f4 (420mm) con la ASI2600MC e filtro Optolong L-Pro. Ho calibrato e allineato i file su DSS a causa di un problema che mi tormenta da mesi su Pixinsight, il resto dell'elaborazione invece fatto direttamente su Pix. C'è qualche artefatto lasciato sulle stelle più luminose, ma devo dire sono molto soddisfatto del risultato ottenuto. Proverò sicuramente nuove elaborazioni per estrarre ancora più segnale

Hi, can you tell us something about this beautiful image: where did you shoot from, what did you use, what software did you edit it with?

Ciao Dongius, è tutto scritto in descrizione ma riporto volentieri qua:
L'immagine è stata ripresa dall'osservatorio astronomico del Lodigiano, a Mairago, quindi nel centro della Pianura Padana.
Sono 28 scatti da 60s realizzati con ASI2600MC e filtro Optolong L-Pro su un Askar 103APO ridotto a 420mm di focale.
Per l'elaborazione ho utilizzato DSS per calibrare e allineare le immagini. In Pixinsight ho poi allineato le immagini sulla cometa ed eseguito una somma per rimuovere il più possibile le stelle, ho poi eseguito una somma standard e rimosso le stelle con Starnet. Una volta ottenuta l'immagine non lineare sia della cometa che delle stelle ho poi fuso le due insieme ottenendo il risultato che vedi qua.
Purtroppo è molto complesso, almeno per me, rimuovere tutti gli aloni lasciati dalle stelle nell'immagine della cometa, alla fine rimane sempre qualche artefatto fastidioso, ma mi accontento Sorriso

Seeing a comet and being able to immortalize it in a shot I think is a fantastic thing.
congratulations!
Greetings,
Luciana

Thank you Gianluca, I hadn't noticed the description below, forgive me.
For me it's a great shot. I will post a much more basic one on Instagram, taken with a 100-400 from the bell tower of my parish also with Opltolong L-pro filter, but in a little time though. I have to make up for the lost months and I like that the photos are in chronological order even if "not in real time" on social media...
