Hi Zeppo thank you, actually more than a mini-course, a video on youtube that opened my eyes to some steps :-D

The improvement between the two images is truly remarkable, congratulations. You really pulled a lot more signal.
May I ask you what you changed in particular between the two images? I imagine the stretch technique :-)

Ciao Gianluca, essendo relativamente nuovo in questo mondo e quindi avendo molto da imparare, i passaggi che ho modificato in realtà sono credo utilizzati da tutti e prima non gli davo peso sbagliando quindi, semplicemente una volta preparata la foto, prima dello scretch, tolgo le stelle, elaboro separatamente il layer della nebulosa e il layer delle stelle, poi passo i file tif su photoshop e dopo una elaborazione finale del layer con le nebulose, li riunisco. Questo semplice passaggio, con un pelino di pratica lo diventa, mi ha permesso di ottenere moltissimo più segnale senza avere le stelle troppo invasive. Probabilmente ci saranno altri metodi più efficaci, ma ripeto, essendo nuovo e autodidatta, comincio a essere contento dei risultati.
