Why do I Have to Configure Stellarium?
When Stellarium is downloaded onto your computer, it is not
connected to the internet anymore, so it can't automatically register
itself to your time and location. When you install Stellarium, you have
to configure the program to your location and time in order to see the
same sky appear on the screen as appears above you. Most of Stellarium’s
configuration is done using the
Configuration Window and the
View Window. To open the
Configuration Window, click the button on the Left Side Toolbar, as shown above, or press F2. To open the
View Window click the button on the Left Side Toolbar, as shown above, or press F4.
Setting the Date and Time
The current date and time is displayed at the bottom of the
screen. If the date and time displayed is incorrect, you may change it.
Open the Left Side Toolbar and click on the
Date/Time Window
as shown above. A small window will appear which will allow you to
change the values for the year, month, day, hour, minutes and seconds by
typing new values, by clicking the up and down arrows above and below
the values, or by using the mouse wheel.
Setting Your Location
The positions of the stars in the sky are dependent on your
location on Earth (or other planet) as well as the time and date. For
Stellarium to show accurately what is (or will be/was) in the sky, you
must tell it where you are. You only need to do this once - Stellarium
can save
your location so you won’t need to set it again until your location
changes. To set your location, click on the
Location Window button, as shown above, or press F6. There are a few ways you can set your location:
1. Just click on the area where you are located on the map.
2. Search for a city where you live using the search
edit box at the top right of the window, and select the right city from
the list.
3. Enter a new location using the longitude, latitude and other data.
Once you’re happy that the location is set correctly, click on the
“use as default” check box, this will save your location so you won't
need to set it again unless you move. Then close the location window.
The Configuration Window
The
Configuration Window contains general program settings, and many other settings which do not concern specific display options. To display the
Configuration Window,
click on the button shown above, or select F2. A small window will
appear. At the top of this window you will see several tabs you can
select. The
Main tab is selected in the diagram above, and the options of this tab are explained below.
-
Program Language allows you to select the language you would like the program to use.
-
Selected Object Information allows you to specify how much information is shown about selected sky objects
-
Default Options allows you to save the current program configuration.
The Navigation Tab
The
Navigation Tab allows for
enabling/disabling of keyboard shortcuts for panning and zooming the
main view, and also allows you to specify which simulation time should
be used when the program starts:
-
When
System date and time is selected, Stellarium will start with the simulation time as the operating system clock.
-
When
System date at is selected, Stellarium will start
with the same date as the operating system clock, but the time will be
fixed at the specified value. This is a useful setting for those people
who use Stellarium during the day to plan observing sessions for the
upcoming evening.
-
When
Other is selected, a fixed time can be chosen which will be used every time Stellarium starts.
-
Show flip buttons When this option is enabled, two buttons will be added to the
Main Toolbar,
which allows the main view to be mirrored in the vertical and
horizontal directions. This is useful when observing through telescopes
which may cause the image to be mirrored.
The Tools Tab
The
Tools Tab of the configuration window contains miscellaneous utility features:
Spheric mirror distortion: This option pre-warps the
main view such that it may be projected onto a spherical mirror using a
projector. The resulting image will be reflected up from the spherical
mirror in such a way that it may be shone onto a small planetarium dome,
making a cheap planetarium projection system.
Disc viewport: This option makes the main view produce
the effect of a telescope eyepiece. It is also useful when projecting
Stellarium’s output with a fish-eye lens planetarium projector.
Gravity labels: This option makes labels of objects in
the main view align with the nearest horizon. This means that labels
projected onto a dome are always aligned properly.
Select Single Constellation: This option allows
you to view one constellation in the sky at a time. Select the box and
then click on one of the stars within one of the constellations. All the
other constellations will disappear.
Auto zoom out returns to initial field of view: When
enabled, this option changes the behavior of the zoom out key (\) so
that it resets the initial direction of view in addition to the field of
view.
Screenshot Directory: This option allows you to select
the folder you would like to save your screenshots in. Click on the
folder beside this option. A window will appear which will allow you to
browse through your folders.
Star Catalog Updates: This option allows you to download more stars into the Stellarium database.
The Scripts Tab
The
Scripts Tab has several short video
demonstrations about different phenomena that happen in the sky. You can
browse through and select the script you would like to watch, and then
press the play button at the bottom of the window.
The View Settings Window
The
View Settings Window controls many display features of Stellarium which are not available via the Main Toolbar. You can display the
View Settings Window
by selecting the icon shown above, or by hitting F4 on the keyboard.
This window has several tabs at the top which will allow you to do
different things when each one is selected. The diagram above is
displaying the
Sky Tab, and the options are described below.
The
Sky Tab of the
View Settings Window contains settings for changing the general appearance of the main sky view. Some options are described below:
-
Absolute scale is the size of stars as rendered by Stellarium. If you increase this value, all stars will appear larger than before.
-
Relative scale determines the difference in size of bright
stars compared to faint stars. Values higher than 1.00 will make the
brightest stars appear much larger than they do in the sky. This is
useful for creating star charts, or when learning the basic
constellations.
-
Twinkle controls how much the stars twinkle.
-
Dynamic eye adaptation When enabled this feature reduces the
brightness of faint objects when a bright object is in the field of
view. This simulates how the eye can be dazzled by a bright object such
as the moon, making it harder to see faint stars and galaxies.
-
Light pollution is common in urban and suburban areas, the sky
is brightened by terrestrial light pollution reflected in the
atmosphere. Stellarium simulates light pollution and is calibrated to
the
Bortle Dark Sky Scale where
1 means a good dark sky, and 9 is a very badly light-polluted sky.
-
Planets and satellites this group of options lets you turn on
and off various features related to the planets. Simulation of light
speed will give more precise positions for planetary bodies which move
rapidly against background stars (e.g. the moons of Jupiter). The
Scale Moon option will increase the apparent size of the moon in the sky, which can be nice for wide field of view shots.
-
Labels and markers you can independently change the amount of
labels displayed for planets, stars and nebulae. The further to the
right the sliders are set, the more labels you will see. Note that more
labels will also appear as you zoom in.
-
Shooting stars Stellarium has a simple meteor simulation
option. This setting controls how many shooting stars will be shown.
Note that shooting stars are only visible when the time rate is 1, and
might not be visible at some times of day. Meteor showers are not
currently simulated.
The Markings Tab
The
Markings Tab of the View window controls the following features:
Celestial sphere this group of options makes it possible to plot various grids and lines in the main view.
Constellations these controls let you turn on and off
constellation lines, names, art and boundaries, and control the
brightness of the constellation artwork.
Projection Selecting items in this list changes the projection method which Stellarium uses to draw the sky. Options are:
-
cylinder The full name of this projection mode is
cylindrical equidistant projection. The maximum field of view in this mode is 233 degrees.
-
equal area The full name of this projection method is,
Lambert azimuthal equal area projection. The maximum field of view is 360 degrees.
-
fisheye Stellarium draws the sky using
azimuthal equidistant projection. In fisheye projection, straight lines become curves when they appear a large angular
distance from the center of the field of view (like the distortions seen
with very wide angle camera lenses). This is more pronounced as the
user zooms out. The maximum field of view in this mode is 180 degrees
-
Hammer-Aitoff The Hammer projection is an equal-areamap
projection, described by Ernst Hammer in 1892 and directly inspired by
the Aitoff projection. The maximum field of view in this mode is 360
degrees.
-
mercator Mercator projection preserves the angles between
objects, and the scale around an object the same in all directions. The
maximum field of view in this mode is 233 degrees.
-
orthographic Orthographic projection is related to perspective projection, but the
point of perspective is set to an infinite distance. The maximum field of view is 180 degrees.
-
perspective Perspective projection keeps the horizon a straight
line. The maximum field of view is 150 degrees. The mathematical name
for this projection method is
gnomonic projection.
-
stereographic This mode is similar to fish-eye projection mode. The maximum field of view in this mode is 235 degrees.
The Landscape Tab
The
Landscape Tab of the
View Window
controls the landscape graphics (ground). To change the landscape
graphics, select a landscape from the list on the left side of the
window. A description of the landscape will be shown on the right. Note
that while landscape can include information about where the landscape
graphics were taken (planet, longitude, latitude and altitude), this
location does not have to be the same as the location selected in the
Location window, although you can set up Stellarium such that selection
of a new landscape will alter the location for you. The controls at the
bottom right of the window operate as follows:
-
Show ground This turns on and off landscape rendering (same as the button in the main tool-bar).
-
Show fog This turns on and off rendering of a band of fog/haze along the horizon.
-
Use associated planet and position When enabled, selecting a new landscape will automatically update the observer location.
-
Use this landscape as default Selecting this option will save
the landscape into the program configuration file so that the current
landscape will be the one used when Stellarium starts.
The Starlore Tab
The
Starlore Tab of the
View Window
controls which culture’s constellations and bright star names will be
used in the main display. Some cultures have constellation art (Western
and Inuit), and the rest do not.
