AstroVideos
by Lorenzo Comolli & Alessandro Gambaro (and other friends)

Here are a number of astronomical videos realized using a DSLR camera and time-lapse shootintg. The resulting videos are in our opinion quite amazing, showing the star motions, the Sun setting or rising and other interesting phenomenas. A detailed explanation of the techniques is here (sorry, only Italian language).
File formats: by clicking on the thumbnails you'll download the AVI files
(DivX required). To overcame of the problems that sometimes AVI files create, you can view the same videos also as Flash SWF by clicking on the link in the caption (Flash required). But be aware that this alternative has a lower quality.
