Introduction
Orrery displays the orbital positions of the nine planets around The Sun. Animate the display to easily visualise elongations of Mercury and Venus, and oppositions of the outer planets. In the information window you call up detailed information for each planet and get its current distance from the Sun. The Sun Rise Set screen shows you the rise, set and transit times of the sun and the end and start times of the twilights. The Planet Rise Set window let's you easily plan your observing sessions showing you the planets' rise, set and transit times and the sun rise and set times and twilights in one graphical display.
Orrery works on all b/w, grey scale and colour Palm OS devices with Palm OS 2.0 or greater.
In the orbital screen you can choose between displaying the Inner ( I button) and Outer (O button) planets. On the outer planets view Earth is indicated by a small dot orbiting the Sun.
D-Pad: Press LEFT or RIGHT to switch between the inner and outer planets views. Keep LEFT or RIGHT held down to access the menus. Press SELECT to reset the time to the current system time.
The Planets Rise/Set view shows a graphical representation of the Sun rise and set times, the twilight times and the planets' rise, transit and set times. Use it to easily plan your observing sessions.
D-Pad: LEFT or RIGHT changes the dates by one day, UP or DOWN by the time increment selected in the menu. SELECT exits the screen.
The Sun Rise/Set screen shows the rise, transit and set times of the Sun and the end and start times of the twilights.
D-Pad: LEFT or RIGHT changes the dates by one day, UP or DOWN by the time increment selected in the menu. SELECT exits the screen.
In the Planets info screen you can choose between the Ephemeris display and an informational text with statistics of the planets.
D-Pad: Press LEFT or RIGHT to switch between the Ephemeris and Text views. SELECT exits the screen.
