Visual SAT-Flare Tracker 3D

MENU SKY

This menu allows the user to selects the celestial objects to be plotted. However, celestial objects will be plotted only if the Draw Sky option in the Draw menu bar item is checked. This menu is composed by the following items:
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.
