Description

Finalmente finita questa M31. E' l'integrazione maggiore mai fatta in questi primi tre anni di foto, volevo continuare ma mi sembrava che il segnale potesse migliorare ben poco con scatti da 300 secondi Per questo oggetto ho speso 3 serate: una ad agosto e due a ottobre. Rispettivamente sono 16x300, 95x300 e 38x300 a 800 ISO con Canon 450D e Tecnosky 80/480.

E' una composizione HDR con 31x30 a 800 ISO per il nucleo. Elaborazione con PixInsight e Photoshop. Mi sono rimasti alcuni dubbi riguardanti i colori, confrontandole con altre però mi sembra corretta

Nonostante la camera modificata dell'halpha proprio non c'è traccia Se ne riparlerà dopo aver preso il filtro da 12nm

Finally i finished this image about M31 galaxy. It is the biggest integration i have ever made in these first three years of astrophotography. I wanted to continue with more integration but it seemed to me that the signal couldn't improve much more with shots at 300 seconds For this image i have spent 3 evenings: one in August and two in October. Respectively 16x300, 95x300 and 38x300 to ISO 800 with Canon 450D and Tecnosky 80/480.

It's a HDR composition with 31x30 to 800 ISO to the core. Processing with PixInsight and Photoshop. I have left some doubts regarding the colours, by comparing them to other images but it seems correct

In the future i will take some data in H-alpha, but i need the filter before!
