Sloan digital sky survey. We are listening. Time-lapse animations. A few dynamic challenges... Everybody knows that the Universe is dynamic. Even absolute beginners immediately recall the day/night sequence, the ever-changing lunar phases, the year's seasons, etc. The Universe has its own time-scale though. In fact, if one excludes meteors and the totality phase of solar eclipses, all other sky events may be considered rather slow.
An increasing number of software packages does allow us to accelerate sky events, but the fact is that reality is hard to duplicate. Fortunately, I am just one of the many amateurs that have so far attempted and did managed to produce astronomical time-lapse animations. I must confess that I do have two more ambitious projects. Image (264KB) small animation (133KB) large animation (463KB) As you can imagine, this time-lapse animation took almost a month to complete.
