- If “system date at” is selected with the custom time, Stellarium starts with current date and the time selected.
- If “Other” is selected the date and time can be changed for Stellarium to start with.
- The first check box if enabled hides the mouse pointer after the time specified in the selector
- The second check box enables and disables horizontal and vertical flip buttons.
Spheric mirror distortion
The tool wraps the Stellarium view to be projected on to a spherical mirror projector.
This tool simulates the view of the sky though a telescope.
This option aligns the object labels to the nearest horizon so that when projected on to a dome, the labels can be viewed properly.
Select single constellation
When star from a constellation is selected, the particular constellation will be highlighted. This option can be enabled and disabled by this check box. The constellation lines must be enabled for this option to work.
Auto zoom out returns to initial field of view
A set of pre-written scripts can be viewed in this tab. The description of the script can be found on the right side when it is selected. The selected script can be invoked using the play button on the right. More scripts can be downloaded from http://www.stellarium.org/wiki/index.php/Scripts.
There are a group of plugins available for stellarium and some are installed while Stellarium gets installed. The plugins can be enabled and disabled in the checkbox. More plugins are available from http://www.stellarium.org/wiki/index.php/Plugins.
