Here
are some 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), or on S&T Aug 2009, Astronomia UAI Jan-Feb

File formats:
File formats:
- AVI format, XviD codec required, download here (Win or Linux), or here (Mac). This is the best choiche for image quality, but unfortunately some users found that AVI files are not accessible, so we've put also an alternative in...
- Flash
SWF format, Flash required. Be aware that this
alternative has a lower quality, so we advise to look at AVI files.
Sometimes the quality is really bad and we cannot improve anymore due
to codec limitations.
- In the past we've used also the AVI-DivX codec, that is quite popular. This codec is a quite old implementation, and generates a lot of quality problems. XviD is by far better, and moreover, this codec can read also our old DivX videos. Thanks to Valerio Messina for letting us discover the XviD codec!
