An unlucky attempt

Last night I spent more than one hour to obtain a decent polar alignment. Then I pointed at NGC 4565, a nice on-edge galaxy, to take 160 1 min shots. The first one showed the galaxy on the bottom left part of the photo, so I did some trial and error samples to center the galaxy. I succeded after 4 shots, then I let the camera work automatically and went to bed. This morning I have discovered that only 47 shots were good because of the late night dew on the correcting glass...
Anyway this is the result.
