Hello,

Try looking for a interactive version of the "Sloan Digital Sky Survey"(Celestia is one), it is a 3d model that allows you to fly/travel between any known celestial objects you like within a defined distance from us.

It allows you to set the speed you wish to travel at between objects etc and gives you a simulation of the trip. (suddenly saying a millions of miles an hour just doesn't cut it for speed.)

Not really a star map for alt/az etc, but great for spatial orientation of whats' around us and the zoom out is impressive...

Ps. Another way to look at it, a little over 1 second for light to travel from the Earth to the moon, over four years for light from the nearest star... (go roughly 31.5m seconds a year)

The moon's diameter is about 3474km, distance from Brisbane to Geraldton WA as the crow flies is 3753km, Sydney-Perth 3290km, so you basically looking at an Australian sized object at 384k or so km. Or how big Australia would look after you had been travelling for 1light second after leaving Earth.
