Animated Lunar Occultation

This is a series of 10 one second exposures of the moon approaching Alcyone - the brighte Pleiad - and occulting it.  You can see two other fainter stars disapperaing as well.  The 10 exposures span a time of about 5 1/2 minutes.  The individual images were aligned on the stars so that we can see the disk of the moon drifting across the stars.  On each image the bright part of the crescent moon is just out of the picture to prevent lens flare and over exposure.
