Time lapse view of planets

    In 1995 I bought a program called "Expert Astronomer." One of the features I
    really enjoyed was the ability to jump, either manually or automatically, one
    day, one month, one year, etc at a time. If you wanted to see how two planets
    approached each other, you could see them move a day at a time while the
    background stars remained static. I don't think you can do the equivalent
    thing with Stellarium.

    You can jump some periods of time with keyboard commands. From the help dialog
    (press F1):

    • Subtract 1 solar day
      8 Set time to now
      = Add 1 solar day
      Add 1 solar week
      Alt+- Subtract 1 sidereal day
      Alt+= Add 1 sidereal day
      Alt+ Add 1 sidereal week
      Ctrl+- Subtract 1 solar hour
      Ctrl+= Add 1 solar hour

    No month of year, although you could write a script to demonstrate such time

    This is a clip to show Venus, Jupiter, the Moon and the Pleiades during March
    and early April.

    I used the following script to produce screen shots every day, then used a
    program to combine the images into a clip.

    before the script you have to set the viewing direction to West. Timing is
    applicable to my region in Saudi Arabia

    for (i=0; i<35; i++)
    core.setDate("+1 days")
    core.screenshot("jv", false);

    The clip is here: http://www.youtube.com/watch?v=VLPu8qH2dbU&context=C4d7c730
