FIXME Please, correct my poor english :-\

The Display setting has nine tabs:

Display

Stars and deep sky objects appearance.

You can display deep sky objects outline (Line mode) or area (Graphic)

You can display stars as drawing (Line mode), photographic aspect simple or with parameters : In parametric mode, you can choose apparent stars size, brightness, contrast and colour saturation. Four combinaisons of these parameters are buit-in : Default, Naked eye, Hight color and Black/white.













Display colour

In this menu, you can change the color of the objects, lines and grids which are drawn at the chart. Therefore you have to click on the color-spots below the related label.

In the group-box Standard Color you can choose a predefined color-scheme: Default will display the colors on the chart like you can see them on real sky. Red will change to a eye-gentle color-mode (red shades), White on black display chart in black with a white background and Black on white display chart in white on a black background (the two last labels seem to be switch around).

In the groupbox Night Vision Button and Default Button you can define the displayed color-theme when the Night Vision Button in the Main Bar is activated or not.










Deep sky object colour

The deep sky objects which you can see on sky are very different. In this Dialog, you can give the different objects different colors for a better differentiation on the virtual chart.


















Sky Background colour

In this dialog you can select the background-color of the map. If in the sky color groupbox the item Fixed Black is marked, the backgroud of the chart will have the same color any time. If the item Automatic is marked, the background-color will correspond to the (nautical/astronomical) twilight.

You can modify fixed color or twilight color-scheme when you click on colour areas.
















Lines

Here you can activate the lines which are shown at the chart and choose the line-mode they are drawn:

Show Coordinate Grid will draw the grid of the coordinate which is set in configuration-menu 3-Chart, Coordinates → 1-Chart, Coordinates → Chart Coordinate System. You can add the equatorial grid by marking Add Equatorial Grid. This grid will be very useful if your telescope has a paralactic mounting. The meaning of Show ecliptic and Show Galactic Equator should be clear. Show Grid Label will show the coordinates in degree at the chart.

Now you have some adjust possibilities in four groupboxes:



Labels

the Display labels checkbox control all labels except grids labels (controled by Show Grid Label in Lines tab).

If you want to display chart informations in the menu bar, check Display the chart ... checkbox.

With the Label Object panel you can control labels font color and size accordind to objects class. Other label show compass directions on the horizon line.

In Star Label and Constellation Label panels you can specify labels content.

Magnitude difference is range (0 to 10) witch filter labels according to object magnitude : Less it is more labels are displayed (relate to FOV ranges ?)






Fonts

This tab control font names used by CdC. To change a font, click on font icon at right.

Click on Default button to reset your settings.


















Finder circle

In this tab you can define FOV (in minutes) of your eyepieces and position. Rotation is angle (in degrees) from X axis parallel to celestial equator and starting at center of chart (witch is default position of center of eyepiece) and new position of your eyepiece, Offset is distance (in minutes) between center of chart and new center of your eyepiece.

Finder rectangle

As for eyepiece, this tab allows to define FOV of your CCD cameras. Field is a rectangle with width and height in minutes. It is parallel to celestial equator, at center of chart. Rotation and Offset has same meaning as for eyepiece.
