Real Time Video: the lunar occultation of Saturn was recorded in real time using a webcam (technical details below). The video shows the complete exit sequence which was captured in AVI and converted to MPEG video (15Mb). Please click the Play button below (you may need to click twice):
Video duration 88 secs; start: 20:15:04; end: 20:16:38 GMT
- If you can't play the video or experience buffering problems (jerky motion, etc) you can view the MPEG file here on another media player (click to view, right-click to download).
- Atmospheric turbulence was quite bad, causing the image to distort and jump around - also clouds were passing over constantly causing waves of varying contrast.
Images selected from the video are displayed below, with timings (all in GMT):

Technical Information : The webcam images were taken with a Philips ToUcam Pro using an RCOS 12.5" Ritchey-Chretien working at f/9 on an AP900 GTO mount. The video stream was captured using the ToUcam software and edited using AVIsplit and AVIedit. Editing was only to cut frames from the beginning and end - the sequence frames are unchanged and in real time. The file was converted to MPEG1 using TMPGEnc.
