Click the eToolf icon located on the toolbar to open the setting dialog. Select gNebulash in the left column to open the nebula setting pane.
Nebula display
By default, gMessiersh are selected to be displayed and all of the celestial body groups
are ticked.
As for the information overlay display feature, the box gOverlay namesh is not
ticked.
Nebula display setting screen
Click the eToolf icon on the toolbar and select eNebulasf in the left column to open the setting screen.
Applicable celestial body groups
The desired celestial body type can be selected among the celestial body groups (i.e.
nebulas, star clusters and galaxies) recorded in the Revised New General Catalog*1No
celestial bodies are displayed if the box gNoneh is ticked.When selecting Messiers, what
is able to be displayed is limited to Messier celestial bodies *2and celestial bodies
with their photo recorded in StellarWindow*3
When selecting gAll,h all of those recorded in the Revised New General Catalog are displayed
whether or not their photo is recorded in StellarWindow.
Celestial body group setting
Based on the Revised New General Catalog, celestial bodies are divided into small groups allowing you to determine
which group is to be displayed and which is not.
Information display
The name of the desired nebula can be overlaid on the image appearing on the screen. A different display color can be selected for each display item. The box below is not ticked by default.
Information display setting screen
A different information display color can be selected for
each celestial body group. A dark shade of purple is selected
for all of the groups by default.
A different information display color can be selected for each celestial body group. A dark shade of purple is selected for all of the groups by default.
The information of the individual celestial body is displayed
in the following order: common name, Messier number and
NGC number.

Delay load of high-resolution photos allows you to determine whether or not to load high-resolution photos when the image of the desired nebula 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 nebula is enlarged. Without performing delay load, low-resolution photos are used. 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 photos of
nebulas and star clusters were installed during the customized installation *4 procedure as there is no applicable photo
existing in these cases.
High-resolution photo delay load
Tick the box shown above if prioritizing the photofs 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).
Precautions concerning information display
In the case of a celestial body that has no photo recorded in StellarWindow and that is located
according to the right ascension, celestial declination, azimuthal angle and elevation angle
shown in the information display located in the upper left of the screen, the coordinates of
such a celestial body correspond to those recorded in the Revised New General Catalog. In the
case of a celestial body with its photo recorded in StellarWindow, however, the coordinates
of the photofs center point, obtained after aligning the star chart and the photo, are displayed.
Please be aware that, depending upon the photofs trimming condition, the coordinates recorded
in the catalog and the right ascension and celestial declination displayed on the screen may
be misaligned for approximately one minute.
Please also note that the right ascension and celestial declination displayed on the screen refer
to the coordinates of the crossover point obtained by connecting the individual selection
markers*5and that the photo and the star chart have been aligned.
The right ascension and celestial declination of a celestial body with its photo recorded in StellarWindow
In the case of a celestial body with its photo recorded in StellarWindow, the right ascension and celestial declination displayed on the screen may differ from those recorded in the catalog.

*2 Photos
A number of photos of
nebulas, star clusters
and galaxies have been
provided by Jim Misti of
the Misti Mountain Observatory,
United States.
I would like to take advantage
of this opportunity to
express our gratitude to
Jim.
*3 Applicable celestial body groups
Please be aware that NGC
celestial bodies with
their photo recorded in
StellarWindow are also
displayed in addition to
Messier celestial bodies.
*4 Setup options
Please refer to the gInstallation
Guideh that comes with
the product or thegAdditional
information: Customized
installationhfor further
details concerning the setup
options.
Please be aware that
the high-resolution photos
of nebulas and star clusters
do not exist if the minimum
installation has been carried
out. It is optional not to
install the high-resolution
photos of nebulas and star
clusters by using the customized
setup procedure.
The high-resolution photos
of nebulas and star clusters
can be additionally installed
later on.
*5 Crossover point of the selection markers
Refers to the crossover
point of the direct lines
that connect the individual
red selection markers.
In the case of M90 shown
above, the selection
marker crossover point
and the photofs rough center point
are almost identical.
