I also have Astronomer for Windows, Redshift 2 and Orbits 3 but none of them do what I want.
I am looking for something like the setup they have at the Planetarium which shows the near planets (Mercury, Venus, Earth and Mars) orbiting the Sun. I would particularly like to see exactly how the Earth orbits the Sun. In 2D it just goes round in a circle.
pj123, would it be worth getting in touch with someone at Joddrell Bank? They might at least be able to point you in the right direction. Last time I saw an orrery I was wearing short trousers in school, middle of lat century.
pj In Celestia you can position yourself above the Sun and watch from any distance , the orbits are correct,Earth orbit isnt that elliptical I just tried it, the planets speed up etc. Some of the people on the forum work in observatories, write educational stuff and so on, there are some scripts for Celestia that take you on a tour and the like.
