However the apparent size of the star reflects observations made by optical instruments, such as the human eye or a telescope equipped with a camera. Stellarium utilizes this approach as well. This shortcoming is remedied by using instruments to adjust the surface of each star according to its observed brightness. Because these spheres are dependent on a single source of light, they cannot account for variations in the brightness of the objects. Large, real-life planetariums project displays of celestial objects by transmitting light through perforated spheres. , except for the new stars, which are stored in ~/.stellarium/stars/default

All of the extensions are stored in ~/.stellarium/ Storing the catalog in this location prevents the user from accidentally making modifications.

The star catalogs for the basic version of Stellarium are found in the program directory /usr/share/stellarium/stars/default A particular star with this magnitude is discussed later in this article. Catalog 9 extends the range to magnitude 18. Catalog 5 will add almost 2 million stars of up to magnitude 12. Moving the mouse to the left edge of the window lets you select the suitable icon. The option for installing extra data files about stars is found in the Configuration | Tools This setting disallows full-screen mode, thus making the terminal visible. For the first boot, the program should be called with the switch -full-screen no The software generates a status message when booted from the command line.
