On the 4th of August 2014, the Moon passed in front of Saturn as seen from Brisbane, Australia.
Using my 8" Schmidt-Cassegrain telescope (Celestron CPC800) and a Canon 600D DSLR camera, I took one image every 15 seconds of the event, and combined the resulting images into this video.
There has been a fair amount of post-processing done on the images to get to this result. The first stage was to adjust the source images so that detail was visible both on Saturn and on the Moon. This is because the two objects are quite different in brightness, and so each individual exposure results in a slightly over-exposed Moon and a slightly under-exposed Saturn.
After initial processing, the series of images were imported into video editing software, and the resulting footage stabilized to eliminate some small tracking errors between shots. There was also one LARGE tracking error, where I had to physically move the telescope. This was because the Moon was sinking towards the western horizon and some nearby, large trees which would have obscured the shot had the scope not been moved. This can be seen in the resulting footage as the period where the Moon appears to slow down and slightly change direction.
Finally, the footage was a little short for my liking, so I slowed the frame rate and added some processing to smooth out the jerkiness that would otherwise have been apparent.
