First night after holidays

Yesterday it was a full moon night... I thought it was impossible to do anything, but I was wrong.
As a first target I choose the globular cluster M14 in Ophiuchus when the moon was just under the orizon, then I did some shots at Albireo and last I pointed at the NGC6503 dwarf galaxy that was exactly in the opposite direction of the moon. These are the results:

M31

What a nice night! Yesterday the sky was fairly clear and I went with my friend Stefano up to Basati, a small hamlet on the Alpi Apuane not far from Pietrasanta. Just parked the car and we immediately saw the bright ISS (International Space Station) passing fast from west to east. Then we started to set the camera, pointing it towards the Andromeda galaxy. After 85 frames with 20 secs of exposure, we have obtained this picture:
