- Visible Sky Only
- Stars On Globe
- Sun and Moon
- Constellations
- Star Names
- Front Stars
- Back Stars
- Sky Circle
- Maximize Sky
- Reverse Sky
- Flat Sky
Draw Sky Map
By checking on this item several sky controls will be automatically set in order to produce a sky map.
Auto Select Max Magnitude
By
checking this item the maximum star magnitude will be
automatically set depending on the zoom factor in order to optimize the
number of plotted stars without filling the graphical window.
Visible Sky Only
By checking this item, only the celestial objects that are currently above the observer horizon will be plotted.
Stars On Globe
By
checking this item, the celestial sphere radius will be set to the
earth radius value. This means that all the celestial objects will be
perpendicularly projected on the earth globe. This function can be
useful to see at which globe location a star appears at the zenith.
Sun and Moon
By
checking this item, the Sun and the Moon will be plotted on the celestial sphere, and projected on the Earth Globe as well.
Constellations
By
checking this item, the constellations lines will be plotted.
Star Names
By
checking this item, the names of the major stars will be
indicated. When the name is not available, the ID number is printed
instead.
Front Stars
By
checking this item, the stars that are located in front of the
Earth Globe will be represented. The represented stars depend,
therefore, on the view angle.
Back Stars
By
checking this item, the stars that are located behind the Earth
Globe will be represented. The represented stars depend,
therefore, on the view angle.
Sky Circle
By
checking this item, the celestial sphere will be highlight.
Maximize Sky
The
radius of the celestial sphere can be changed with respect to the
radius of the Earth. By checking this option the celestial sphere
radius is automatically changed and set in order to fit all the
graphical window with the celestial sphere.
Reverse Sky
By
checking this item, the sky east-west direction will be reversed.
This function is useful to plot the sky as an observer will actually
see it looking upwards.
Flat Sky
By
checking this item, the sky will be flatten in order to produce a
representation that is not affected by compression along the
borders. This function is useful in combination with the previous Reverse Sky option to produce a sky map.
