Click the ‘Tool’ icon located on the toolbar to open the setting dialog. Click “Planets” in the left column to open the planet setting pane.
Planet display
None of the boxes other than “Display planets and satellites” is ticked by default. Planets and planetary satellites are displayed as point images resulting from the calculation of the current magnitudes.
The target planet/planetary satellite’s name, distance and/or the planetary orbit can be overlaid on its image appearing on the screen. Light blue that are specified as the default display colors can be altered by using the color selection feature*1for the individual items displayed on the screen.
Planet display setting screen
Click the ‘Tool’ icon located on the toolbar and select “Planets” in the left column to open the
planet display setting screen.
The name, distance and
planetary orbit appearing
on the screen in the
case of Mercury
Screenshot showing Mercury with its name, distance and orbit overlaid on its image. The color describing the planetary orbit is altered to bright blue.
The ‘distance’ described in kilometers refers to the distance between the location of the eyepoint on the Earth and Mercury. The significant figure differs according to the planet/ planetary satellite.
While the planetary orbit of Mercury and Venus takes shape of a narrow ring on the screen, this is not the case for the other planets due to their orbit located outside of the earth.
When running StellarWindow using the sensor, keep the planetary orbit remain on the screen and move the sensor along the orbit so that a rough idea of the orbit’s shape (=the way the planet actually circles around you) can be obtained.
StellarWindow provides no special setting to observe solar eclipses. What you can observe
is simply the moon and the sun overlapping with each other. The diamond ring as a result of
a solar eclipse is not reproduced with StellarWindow.
When observing a lunar eclipse, the shadow of the earth is reproduced. While the size of
the moon displayed is larger *3 than the actual size so as to obtain display effects that are
easy to recognize, the progress status of a lunar eclipse is accurately reproduced. No special
calculation is however carried out to reproduce the color of the shadow created as a result of a lunar eclipse.
Multiple photos of the lunar eclipse are analyzed and the average color observed within the shadow is
simply overlapped on the image.

StellarWindow carries out no special calculation to reproduce solar eclipses. What you can observe is simply the moon and the sun overlapping with each other.
The diamond ring as a result of a solar eclipse is not reproduced with StellarWindow.

The shadow of the earth is reproduced except for its color. The color of the shadow is therefore not accurate.
Delay load of high-resolution photos allows you to determine whether or not to load highresolution
photos of the surface of the desired planet when the image of such a planet is
enlarged. By default, this feature is disenabled in the Light Mode while it is enabled in the
Standard Mode.
Delay load enables the use of high-resolution photos with the level of visual quality appropriate
for observation when the image of the planet is enlarged. Without performing delay
load, low-resolution photos are used for a closer look. This however does not use up extra
memory therefore enabling StellarWindow to perform faster and lighter operations.
When using a small-size laptop with a small screen (i.e. net books), adequate resolutions
may be obtained without performing delay load. Delay load is unlikely to be able to be performed
in the case of an inadequate amount of remaining memory.
It is not possible to perform delay load if the minimum installation (setup option) has
been carried out or if no planet surface photos were installed during the customized
installation*3procedure as there is no applicable photo existing in these cases.
StellarWindow automatically examines the performance level of your PC’s 3D drawing
environment (OpenGL environment) during the delay load process to enable the photo to be
displayed by using a maximum resolution allowable.
High-resolution photo delay load
Tick the box shown above if prioritizing the photo’s visual quality over the operation speed (the box is ticked in the Standard Mode by default). If not, do not tick the box (the box is not ticked in the Light Mode by default).

*1 Color selection feature
Click the “Color well”located in the right side of the screen to open the color selection dialog.
The color selection methods correspond to those applicable to
stars.
*2 The size of the moon
Although the moon displayed on the screen is 3 to 4 times larger than the actual moon, the wax and wane alongside the phases of the moon are accurately reproduced.
*3 Setup options
Please refer to the “Installation Guide” that comes with the product or the “Additional information: Customized installation”for further details concerning the setup options.
Please be aware that the planet surface high-resolution photos do not exist if the minimum installation has been carried out.
It is optional not to install the planet surface highresolution photos by using the customized setup procedure.
The planet surface highresolution photos can additionally installed later on.
