Celestia User’s Guide 9 of 48

Once you have obtained and downloaded the executable file from the Celestia website, simply click twice

(double-click) rapidly on its name with your left mouse button. The file will begin running and will install

Celestia in your C:/Program Files Directory. In general, just click “Next” whenever it asks a question. Celestia

has its preferred choices and unless you have good reasons for altering them, we suggest you follow them.

Macintosh OS X Operating Systems:

To install the Macintosh version, click on the installation file and follow the on-screen menu instructions. We

recommend installing the program in the Applications folder.

NOTE – Celestia uses a special hyperlink file internally within the program called a .cel: //URL file. When

you click on a .cel: //URL, the program treats it as a kind of “address” and will respond by going to a

particular place and time in the night sky. It is similar to the way web browsers such as Internet Explorer

and Firefox go to certain web pages when you click on a hyperlink address.

In the Windows installation program, the install procedure automatically “associates” Celestia as the

program that utilizes .cel: //urls. In the Apple MAC OS X operating system, however, association of .cel: //

url file links to Celestia is not automatic. If you are using an older version of OS X, you have to do it

manually. New versions of OS X correct the problem, however. Be sure to visit the Apple.com site and

update to the latest version of OS X. If you do not do this, some aspects of Celestia will not work properly.

For example, if you click on a .cel: //URL file without associating it with Celestia, your web browser will

launch instead and try to take you to the Internet. You may get a message saying, “Page not found”.

Linux Operating Systems:

Most distributions package Celestia to best suit their users' needs. Check with your package management

software, as there is a good chance that Celestia is present there.

Alternatively, there is a precompiled x86 AutoPackage provided on the SourceForge download site. This package

uses the GTK+ front-end, and should run on most computers. Information about installing an AutoPackage is

here: http://www.autopackage.org/docs/howto-install/

Finally, should you wish to compile Celestia yourself, the process is fairly straightforward. Unpack the tarball:

tar -zxvf celestia-1.4.1.tar.gz

Then change directory (cd) into the newly created directory and configure Celestia. Run configure with the

appropriate command line for the version that you want to compile:

KDE

./configure --with-kde

GNOME

./configure --with-gnome

GTK+

./configure --with-gtk

The configure script may complain if you are missing a required component, or if you have an out of date version

of a required component. Check the error output to determine what's missing, install the necessary items, and then

try re-running configure. If neither the KDE or GNOME versions of Celestia will build, try falling back to the

GTK+ version. There are many options for configure; you can view them all with a brief explanation for each-by

running ./configure --help. After running configure, compile and install Celestia:

make

make install

Note: make install will need to be run as root unless you've overridden the default install directory by invoking

configure with the --prefix option.

Updating your Celestia installation:

Celestia User’s Guide 10 of 48

When a new version of Celestia comes out, it is a good idea to uninstall an older version and install the new one,

while archiving any add-ons or other files you may have loaded into your Celestia folder in a safe spot. The

reason is compatibility. Newer versions of Celestia may or may not work well with some of the files from older

versions. Once the new version is in place, you can drag your add-on files back into the new Celestia folder, and

continue using them.

Alternatively, you can choose to install the new version of Celestia in a different folder. Simply name a new

destination for Celestia during the installation of the new version. For example, you can call it “Celestia 2”.

Then, you will be able to launch and run either version of Celestia as you choose, by simply opening the program

from either folder.

Uninstall:

To uninstall Celestia in Windows, click the Start button at the bottom left of your screen, select “Settings”,

then select “Control Panel”, then select Add/Remove Programs. Locate Celestia in the list that appears

and click the button that says, “Add/Remove”. For Apple, LINUX/UNIX owners, follow your system’s

uninstall procedure.

Note: In the sections that follow, images and screenshots from the program are

displayed. Many of the images use higher-resolution graphics that are not part of the

default download program, but which are available from the Celestia forum and other

websites as add-ons. As a result, if your version of Celestia does not precisely match

the enclosed screenshots, don’t be alarmed.

Note: In the following Guide, many keystroke commands will be referenced. All

keystrokes will be enclosed inside a square bracket [ ]. Since all of the letters on a

modern keyboard are in capitals (e.g. – K or L or M), keystroke references will be in

capitals also (e.g. – [ K ] means press the “K” key). You do not have to use the [Shift]

key. On occasion, however, a keystroke will require the use of an actual capital letter,

such as the capital letter “T”. If that happens, we will instruct you to press both the

[Shift] key and the [T] key. For example, the instruction will read, “Press the

[Shift+T] keys”. If the keystroke is a symbol that requires the use of the [Shift] to

reach such as a colon [:] or an asterisk [*], please press the [Shift] key at the same

time as you press the symbol keystroke. For example, to type the & sign, you would

actually press [Shift] and the [ 7 ] key at the top of the keyboard, together at the same

time. Some keystrokes require the use of the [Ctrl] key or [Alt] key. When they do,

we will instruct you.

IMPORTANT NOTE: on occasion, we will instruct you to “Click here” to actually

launch a scene in Celestia. It is VERY important that you click that link ONLY

ONCE. If you double click it, two separate versions of Celestia will launch. Since the

program uses a lot of memory and computer resources, two programs running at the

same time will lock up your computer or slow things down dramatically.

Also note that in Microsoft Word, you may have to hold down the [Ctrl] key while you

click “here”.
