there are also sevl apps whch generate starfields based on astronomic data.  e.g. stellarium, which allows one to generate starfields as seen from various locations/times on earth (see att img) and celestia, which allows one to generate starfields as seen from various locations/times in earth's galaxy.  used in concert with vidcap software, the latter will generate a movie of the observers' view when travelling thru space or rotating around some point in space.  I dunno if any of the carrara plug-ins include actual star/planet charts.
