Stellarium has numerous stars listed in it's star catalog.
|
|
The star catalog data is located in the stars/default sub-directory
|
|
in the installation or ~/.stellarium directory.
|
|
The star catalog splits the data into different files.
|
|
|
|
Each catalog file models stars for one level. Star records do not list the star's full coordinates.
|
|
The coordinates are relative to the central position of the zone the star falls in.
|
|
This means it is important to know the zone model to learn about a star's positional data.
|
|
The following summarizes zone file information.
|
|
|
|
These ship with Stellarium:

[1] The bigger the star catalogue, the more RAM/better OpenGL-capable graphics
|
|
card is required for optimal experience.
|
|
Rule of thumb : if you don't get 60+ fps most of the time with it, star
|
|
catalogue is too big.
