M 45 (Plejades)

This is my first picture of M45 with my C9. After 12 minutes the guide star moved too far away from the center of the crosshairs. I don't look continously through the guiding eyepiece and noticed this movement too late. I use to check the position of the guide star only every 10 to 15 seconds. Nevertheless the blue reflection nebulae around some of the stars are already visible. I have to do this picture again with at least 30 minutes exposure time.
