His vision and dedication gave birth to a program that is unlike any other planetarium program in existence.
Celestia is a space simulation program, not a planetarium program. Planetarium programs are usually limited to looking up, while Celestia gives you freedom of movement through the entire universe, to look in any direction you want.
I do hearby SIT corrected on this one! From the User's FAQ ...

Q19: How can I make Celestia work like a planetarium? I want to see how the sky should look from my backyard.
A19:
0) Select the body from which to observe; the Earth maybe
1) use the GoTo menu to specify your Longitude and Latitude and GoTo there
2) type a y =Sync Orbit
3) type a Ctrl-G =GotoSurface under Windows
or
3) type a Ctrl-S =GotoSurface under Linux
4) type a Ctrl-F =change Arrow keys to AltAzimuth mode
Unfortunately, there is not (yet) an alt-az coordinate system display, but typing a ; will turn on the equatorial coordinate system display.
