Celestia's Controls

Using and navigating inside Celestia is not difficult per se but due to the extensive ways the user can move around it takes some time to get used to it. Navigation is done using a combination of keyboard and mouse commands. These commands are listed in the getting started guide of the official website.

Another way to navigate is to load and execute a script. What's interesting with scripts is that the user can share them with others or load them in a presentation session. In Celestia Motherlode, many community-created scripts are available for free download.

Video and image capture

Another feature is the ability to capture images and videos, which is perfect for creators of scientific and technological content. To take a screenshot go to File => Capture Image.

For video capture go to File => Capture Movie then you will be instructed to configure video settings, after that the frame will appear on the software display then the user needs to click F11 start/pause the video recording and F12 to stop recording.

Celestia scripting

One of the best features of Celestia is the ability to program tours around the cosmos using a scripting language, scripts can be loaded to the software from File => Open script. To learn how to write scripts you can go through the guide on the offical website.
