M31: Andromeda galaxy

I didn't want to take pictures of our bright neighbor because of my Atik's small sensor. The Andromeda galaxy is so wide that SW ED80 Pro with Atik could only manage less than half of it. 

I finally got that camera with bigger sensor (QHY9). Its 8,6 mega pixel sensor provides much bigger field of view than Atik's 1,4 Mp sensor.I had to wait it for over 4 months (manufacturer was improving it) but this is the first light of my new QHY9 monochrome ccd-camera (photographed in October)

Total exposure is about 6,5hrs (LRGB).
