Running Celestia:
Celestia will start up in a window, and if everything is working
correctly, you'll see Jupiter's moon Io in front of a field of
stars. In the left corner is a welcome message and some information
about your target (Io), your speed, and the current time (Universal
Time, so it'll probably be a few hours off from your computer's clock.)
Right drag the mouse to orbit Io and you should see Jupiter and
some familiar constellations. Left dragging the mouse changes your
orientation too, but the camera rotates about its center instead of
rotating around Io. Rolling the mouse wheel will change your distance
to the space station--you can move light years away, then roll the wheel
in the opposite direction to get back to your starting location. If your
mouse lacks a wheel, you can use the Home and End keys instead.
In Celestia, you'll usually have some object selected; currently,
it's Io, but it could also be a star, planet, spacecraft, or galaxy.
The simplest way to select an object is to click on it. Try clicking
on a star to select it. The information about Io is replaced with
some details about the star. Press G (or use the navigation menu),
and you'll zoom through space toward the selected star. If you
press G again, you'll approach the star even closer.
Press H to select our Sun, and then G to go back to our solar system.
You'll find yourself half a light year away from the sun, which looks
merely like a bright star at this range. Press G three more times to
get within about 30 AU of the sun and you will be to see a few become
visible near the sun. Right click on the sun to bring up a menu of
planets and other objects in the solar system. After selecting a planet
from the menu, hit G again to travel toward it. Once there, hold down
the right mouse button and drag to orbit the planet.
Tour Guide
The tour guide is a list of some of the more interesting objects you can visit
Celestia. Select the Tour guide option in the navigation menu to bring up the
guide window, choose a destination from the list, click the Goto button, and
you're off.
That covers the very basics . . .

Star and Planet Browsers:
[For the moment This only applies to the Windows version of Celestia.]
In the navigation menu are 'Solar System Browser' and 'Star Browser'
options. The Solar System Browser pops up a window with a tree view
of all the objects in the nearest solar system (if there is one at all
within a light year of your current position.) Clicking on the name
of any planet in the window will select it; you can then use the center
or goto buttons to see it in the main Celestia window. The star
browser is a window showing a table of the hundred nearest stars,
along with their distances and apparent and absolute magnitudes.
Clicking on the column headers will sort the stars. The table is
not continuously updated--if you travel to another star, you should
press the Refresh button to update the table for your current position.
The radio buttons beneath the table let you switch between viewing
a list of nearest or brightest stars. As with the solar system browser,
clicking on any star name in the table will select it--use this feature
along with the center button to tour the stars visible from any night
sky in the galaxy.
Selecting Objects by Name:
It's possible to choose a star or planet by name. There are two ways to
enter a star name: choose 'Select Object' from the Navigation menu to
bring up a dialog box, or by hitting Enter, typing in the name, and
pressing Enter again. You can use common names, or Bayer designations
and HD catalog numbers for stars. Bayer and Flamsteed designations need
to be entered like this:
Upsilon And
51 Peg
The constellation must be given as a three letter abbreviation and the
full Greek letter name spelled out. Irritating, but it'll be fixed.
HD catalog numbers must be entered with a space between HD and the number.
Celestia handles star catalog numbers in a slightly kludgy way. To keep the
star database size to minimum, only one catalog number is stored. Normally,
this will a number from the HD catalog, but if a star isn't in the HD catalog
the number from another catalog will be used instead. Currently, the secondary
catalog is always the HIPPARCOS data set, for which the prefix "HIP" should be
used.

GETTING STARTED
---------------
Celestia will start up in a window, and if everything is working correctly,
you'll see Earth in front of a field of stars. Displayed on-screen, is some
information about your target (Earth), your speed, and the current time
(Universal Time, so it'll probably be a few hours off from your computer's
clock).
Right drag the mouse to orbit Earth and you might see the Moon and some
familiar constellations. Left dragging the mouse changes your orientation
also, but the camera rotates about its center instead of rotating around
Earth. Rolling the mouse wheel will change your distance to Earth--you can
move light years away, then roll the wheel in the opposite direction to get
back to your starting location. If your mouse lacks a wheel, you can use the
Home and End keys instead.
When running Celestia, you will usually have some object selected. Currently,
it's Earth, but it could also be a star, moon, spacecraft, galaxy, or some
other object. The simplest way to select an object is to click on it. Try
clicking on a star to select it. The information about Earth is replaced with
some details about the star. Press G (or use the Navigation menu), and you'll

Press H to select our Sun, and then G to go back to our Sun. Right click on
the sun to bring up a menu of planets and other objects in the solar system.
After selecting a planet from the menu, hit G again to travel toward it. Once
there, hold down the right mouse button and drag to orbit the planet.
The Tour Guide is a list of some of the more interesting objects you can visit
in Celestia. Select the Tour Guide option in the Navigation menu to display
the Tour Guide window. Choose a destination from the list, click the Goto
button, and you're off.
That covers the very basics. For a more in-depth look at Celestia and the
controls available to you, download the "Celestia User's Guide" (written by
Frank Gregorio), available in several languages, from:
http://www.shatters.net/celestia/documentation.html
This web page also includes links to the Celestia README file translated into
Japanese.
MOUSE, KEYBOARD & JOYSTICK CONTROLS
-----------------------------------
See the included file: KbdMouseJoyControls.txt. In Windows, you can also use
the Help menu to display the Controls list.
SOLAR SYSTEM BROWSER (Windows version only)
-------------------------------------------
The Navigation menu contains 'Solar System Browser' and 'Star Browser'
options. The Solar System Browser displays a window with a tree view of all
the objects in the nearest solar system (if there is one within a light year
of your current position.) Clicking on the name of any object in the window
will select it. You can then use the Center or Go To buttons to display that
object in the main Celestia window.
STAR BROWSER (Windows version only)
-----------------------------------
By default, the Star Browser window displays a table of the 100 nearest stars,
along with their Distance, Apparent and Absolute Magnitude, and Type. Clicking
on the column headers will sort the stars. The table is not continuously
updated, so if you travel to another star, you should press the Refresh button
to update the table for your current position. The radio buttons beneath the
table let you switch between viewing a list of Nearest, Brightest, or 'With
planets' stars. As with the solar system browser, clicking on any star name
in the table will select it. Use this feature along with the Center and Go
To buttons to tour the stars visible from any night sky in the galaxy.
SELECTING OBJECTS BY NAME
-------------------------
Celestia provides several ways to select an object by name...
1. Choose 'Select Object' from the Navigation menu, type in the object
name, and click OK.
2. Press Enter, type in the entire object name, and press Enter again.
3. Press Enter, type in the first few characters of the object name,
press the Tab key to move through the displayed listing until the
object is highlighted, then press Enter again.
You can use common names, Bayer designations, or HD catalog numbers for
stars. HD catalog numbers must be entered with a space between HD and the
number. Celestia handles star catalog numbers in a slightly kludgy way, to
keep the star database size to minimum -- only one catalog number is stored.

KNOWN ISSUES
------------
Many people have reported problems running Celestia with Matrox G400/G450 3D
accelerator cards. As I don't have a Matrox card, I haven't made much
progress on this bug. If you do have a G400, have Visual C++ installed, and
would be interested in testing a debug version of Celestia, please contact me.

your OpenGL driver does not support a required extension. Try upgrading to
the most current version of drivers available for your card. For some older
cards, this still won't fix the problem. The next version of Celestia will
feature a workaround.

Basic Hacking Tips:
USER MODIFIABLE ELEMENTS
------------------------
You can modify how Celestia starts up each time you run it, by defining your
own start-up settings. Simply open the file "start.cel" in a plain text
editor and follow the in-file instructions. Also, view the celestia.cfg file
in a plain text editor to see additional settings.
It's possible to modify the solarsys.ssc, stars.dat, and hdnames.dat
files to create an entirely fictional universe.
Celestia allows you to create an entirely fictional universe, by modifying its
solarsys.ssc, stars.dat, and hdnames.dat files. The easiest file to modify is
the solar system catalog (solarsys.ssc), since it's a plain text file and the
format is very text-editor friendly. It's also quite verbose, but that's not
a problem yet.
The easiest file to modify is the solar system catalog, as it's a text
file and the format is very text-editor friendly since that's how I
had to enter all the data. It's also quite verbose, but that's not a
problem yet.
The units used for the solar system data may not be obvious. All angle fields
in the catalog are in degrees. For planets, the period is specified in earth
years, and the semi-major axis in AU; for satellites, days and kilometers are
used instead.

angle fields in the catalog are in degrees. For planets, the period
is specified in earth years, and the semi-major axis in AU; for
satellites, days and kilometers are used instead.
When adding objects, they should be included in their own sub-directory under
Celestia's "extras" directory. For example:
celestia <dir>
extras <dir>
yourNewObject <dir>
about.txt
install.txt
object.dsc
object.ssc
object.stc
models <dir>
object.3ds
object.cmod
object.cms
textures <dir>
medres <dir>
objectTexture.??? (jpg, png, dds, or bmp)
All solar system textures should be placed in the textures
subdirectory. Currently, JPEG, PNG, BMP, and DDS are the only formats
supported. Models belong in the models directory. Celestia can read 3DS
models, as well as a custom format (.cms files, used right now just for
rough fractal displacement map likenesses of asteroids and small moons.)
3DS meshes are normalized to fit within a unit cube--the Radius field
determines how big they appear within Celestia.
YOU create each of the directories under the extras directory. By using this
structure, activating and de-activating your new objects will be easy. Simply
move the sub-directory "yourNewObject" outside of the extras directory. Some
users have found that adding category-name sub-directories under extras to be
useful, such as:
celestia
extras
Deep Sky Objects
yourNewObject
Galaxies
yourNewObject
Spacecraft
yourNewObject
The stars.dat file is a binary database of stars, processed from
the 50+ meg HIPPARCOS data set. The first four bytes are an int
containing the number of stars in the database. Following that
are a bunch of records of this form:
Texture files should be placed in textures/medres, as shown above. Currently,
JPEG, PNG, BMP, and DDS are the only formats supported.
4 byte int : catalog number
4 byte float : right ascension
4 byte float : declination
4 byte float : parallax
2 byte int : apparent magnitude
2 byte int : stellar class
1 byte : parallax error
Models belong in the models directory. Celestia can read 3DS models, and two
custom formats (.cms and .cmod). The .cms files are currently used for rough
fractal displacement map likenesses of asteroids and small moons. 3DS meshes
are normalized to fit within a unit cube -- the Radius field determines how
big they appear within Celestia.
RA, declination, and parallax are converted to x, y, z coordinates
and apparent magnitude is converted to absolute magnitude when the
database is read.
The stars.dat file is a binary database of stars, processed from the 50+ meg
HIPPARCOS data set. The first four bytes are an integer (int) value
containing the number of stars in the database. Following that are a bunch of
records of this form:
4 byte int : catalog number
4 byte float : right ascension
4 byte float : declination
4 byte float : parallax
2 byte int : apparent magnitude
2 byte int : stellar class
1 byte : parallax error
RA, declination, and parallax are converted to x, y, z coordinates, and
apparent magnitude is converted to absolute magnitude when the database is
read.
