Other tips

  • The moon and umbra are only shown in registered versions. Also, the umbra is only shown when the moon is within 15 degrees of it (at full moon).
  • Remove the horizon (View above horizon only - off) for better animations.
  • Animation speeds are increased by decreasing the number of objects visible.
  • Calculation speed are increased by not drawing constellation boundaries.
  • Watch the earth's rotation: View Towards Equatorial North Pole. Animate by hour.
  • Try viewing the solar eclipse of 1994/5/10: View Towards Sun. Animate by minute.
  • Watch moon phasing and planet motion: View Towards Ecliptic North Pole. Animate by day.
  • Watch the moon get closer and further from earth: View Towards Moon. Animate by day.
  • Watch Venus get closer and further from earth: View Towards Venus. Animate by month. Zoom In.
  • Watch the seasonal motion of the sun: View Towards Direction Horizon South (or North if you live in the southern hemisphere). View at local noon. Animate by civil day.
  • Don't Forget! Right click allows you to toggle Full Screen View.
  • Stars too small when printing? Simply change their brightness in the stars dialog before printing.
  • Are there any recent multi-planet alignments? Try May 5, 2000 from the orrery!
