Settings Artificial Horizon...

  If you select this submenu, then Artificial Horizon Manager will be opened. Artificial Horizon Manager is used to define on the skymap one or more regions that are blocked from view from your current location (&ie; tall trees or building). The window is split in two sections: in the left side is the Regions section while in the right side is the Points section. You can add a new region by pressing the + (Add Region) button or you can remove a region by selecting it in the regions list and then pressing the - (Remove Region) button. In order to draw a region you need to define a list of points that encompasses the blocked area. You can add a new point by pressing the + (Add Point) button from the right Points section. You can also remove a highlighted point from the list of points or you can clear all the points. There are two ways to add a new point to a selected region: manually by entering the point's coordinates or by selecting the point from the skymap after clicking Select Points button. Note that each point is described by a set of horizontal coordinates: Az (Azimuth) and Alt (Altitude). If you want to modify a point's coordinates, just double click on its Az/Alt text box value and enter the new value. First and Last points must be on the horizon. Polygons must be closed to be considered valid regions. Artificial Horizon Manager provides a easy way to rename your regions. By default, regions are named as: Region plus an index (&ie; Region 1 or Region 2). For renaming a region, just double click on its name and then you will be invited to complete a new region name. You can also control which regions are enabled or disabled for marking on the map by a simple click on the checkbox in front of each region. After you defined your desired regions you can apply them by pressing the Apply button. If you want to use these regions again, in further astronomy sessions, you can save them such that next time when you will open &kstars; they will be automatically marked on the skymap.

&Ctrl;1 Settings Manage Observer...

  Selecting this will open Manage Observers window that enables you to register a number of observers which are using &kstars; on this computer. You can add a new entry to observers list by completing the mandatory fields: Name: and Surname: and then pressing the + (Add observer) button. Note that Contact: field is optional, &kstars; allowing you to add a new observer even though Contact: text box is empty. You can also remove an observer from the list using - (Remove observer) button.

&Ctrl;G Settings Geographic...

  Select a new geographic location.

Settings Configure Keyboard Shortcuts...

  Open the Configure Shortcuts window which allows you to modify &kstars; shortcuts. You can use &kstars; default shortcuts scheme or define your own shortcuts scheme. In order to add a new custom shortcut to an action, you need to click on action's name and then press the Custom: checkbox. Then click on the button next to Custom: checkbox and enter the shortcut you would like to use in &kstars;. You can also remove a shortcut by pressing the Delete button after you select an action from the list. &kstars; helps you to find an action by providing its search method; just enter the name of the action and the list will be reduced to its best matches. For example, I will give you a brief example on how to use &kstars; Configure Shortcuts feature:

  - Firstly, open the Configure Shortcuts window from the Settings menu.

  - Then select the action you would like to add a shortcut (&ie; Artificial Horizon). You can use the search method provided by &kstars;. Just type art in the search text box and the list will be reduced to only four actions. The Artificial Horizon is the first action in the list.

  - Now that you find your desired action, you can add a new shortcut by clicking on its name. After you click on the action name, press the Custom checkbox. There is a button next to Custom checkbox used for adding new shortcuts. By default, if an action has no custom shortcut, the None tag will be assigned to this button. Press this button and then add your custom shortcut. For example, for Artificial Horizon, you can use &Ctrl;+H shortcut. Hold the &Ctrl; key and press H. Your shortcut be automatically saved, thus you can use it next time when you open &kstars;.

The first page of Setup Wizard is a welcome page and if you press Next button, you will get the Choose Your Home Location page. Here you can select your exact home location or a city near your home location if your accurate location is not present in &kstars; cities database. Browsing the entire list is not so efficient and thus, &kstars; provides you a easy-to-use method for selecting your desired city in a short time. You may filter the list of cities by the name of your city, province and country. By giving more details about your location, the list's size will reduced only to its best matches. When you highlight a city in the cities list, the Longitude: and Latitude: boxes will be updated, containing the accurate information of your selected location. When you hit the Next button, you will get the last page of &kstars; Setup Wizard: Download Extra Data Files page. Here you may download optional data files via the Internet, in order to enhance &kstars;, such as Messier object images, or a more complete NGC/IC catalog. Press the Download Extra Data... button to proceed. After you pressed this button, the Get Hot New Stuff dialog will appear. It is &kstars; Add-On Installer, which will help you to manage what extra information you added to &kstars;. Firstly, you can choose how the add-ons list is displayed, by pressing the Details view mode or Icons view mode button. You may also order the list by various criteria like: newest, rating, most downloads or installed. This can be easily done by selecting an option using the radio button. You can also make searches using the Search: text box. Regarding the list of add-ons, you may perform several actions by selecting an add-on from the list: you can install or uninstall an add-on using the Install / Uninstall button, you can open the Details window using the Details button or you can rate an add-on by giving a number of gold stars, up to five stars. If you want to send an email to the author of an add-on, you are able to do that by clicking on his e-mail address. Then, your default e-mail application will guide you through the sending process. After you managed your &kstars; add-ons, then you can close the window by pressing the Close button. You can also use the Download Extra Data Files tool later, by selecting the Data Download New Data... menu item.

### Help Menu

&kstars; has the common &kde; Help menu items, for more information read the section about the Help Menu of the &kde; Fundamentals.

### Popup Menu

The right click popup menu is context-sensitive, meaning its content varies depending on what kind of object you click on. We list all possible popup menu items here, with the relevant object type [in brackets].

[All]

  Identification and quick info: The top several lines are devoted to the name(s) of the object, its type and the constellation in which it lies. The magnitude is shown with the superscript 'm' if it is available. For stars, the Spectral Type is also shown here. For deep-sky objects, the dimensions, if known, are shown in arcminutes (eg: 6'×3') and the source catalog is also shown.

[All]

  Rise, Transit, and Set times for the object on the current simulation date are shown on the next three lines.

[All]

  Center & Track: Center the display on this location, and engage tracking. Equivalent to double-clicking.

[All]

  Add flag...: Open &kstars; Flag manager window. Here you can manage your flags and use some of &kstars; features. When Flag manager window is open for a selected object, Right ascension and Declination text boxes will be automatically filled with the coordinate values of the selected object on the Sky Map. Besides these two text boxes, you can set the Epoch, add a Label, set the Label color or even add an Icon. To add custom icons, just add images in ``qtpaths --paths GenericDataLocation`/kstars/`. File names must begin with the flag keyword. For example, the file flagSmall_red_cross.gif will be shown as Small red cross in the combo box. After you set up the information of the new flag, you can add it to the flags list using the Add button. You may also change flags details (&ie; RA/Dec, label or icon) and then save the new ones by pressing the Save changes button. Using the Flag manager, you can easily center an object in Map or in Telescope, by pressing Center in Map or Center in Telescope button. In order to delete a value from the list, just select it in the list and then press Delete button. Your flags are saved after you close current session and thus you will be able to see them everytime you will use &kstars; again.

[All]

  Angular Distance To...: Enter "angular distance mode". In this mode, a dotted line is drawn from the first target object to the current mouse position. When you click with the &RMB; on a second object, this will display the angular distance between the two objects near the second object. You can press the &Esc; key to exit angular distance mode without measuring an angle.

[All]

  Starhop from here to: will enable you to find a path between two points in the sky. Star hopping is a technique that uses bright stars as a guide for finding fainter objects. So if you have a bright star, you can use it as a reference to find a fainter object. Starting from your reference star, &kstars; will find a route to the destination, traversing a sequence of stars/patterns of stars. The object for which you called Starhop from here to tool will be your starting point. When your starting point is established, a dotted line will appear, allowing you to decide which will be your end point. You have to move the mouse cursor to your destination object position and right click on it. Then, a dialog box will pop up, requiring you to set the FOV used for star hopping. For selecting a FOV, you need to make a choice from the FOV combo box list of values. The values you can choose include default FOV values (7x35 Binoculars, Telrad, One Degree, HST WFPC2 and 30m at 1.3cm) plus your customized FOVs. After you selected the FOV, &kstars; will find a route for you. Thus, the dialog box will contain a list of object used in the starhop. If &kstars; did not manage to find a route, then an error dialog box will be displayed, giving you a helping hand. When the Star-Hopper algorithm ends, the dialog box will contain a list of objects used in starhop route. For every object from the list, you can perform a set of actions: you can ask for details using the Details button, center selected object in the map using Center on map button or you can go to next star by pressing the Next button. Note that when go to next star, it will be automatically centered on the map. Also, Star-Hopper tool provides directions to star hop for every object of the list.

[All]

  Details: Open the Object Details window for this object.

[All]

  Attach Label: Attach a permanent name label to the object. If the object already has a label attached, this item will read Remove Label.

[All]

  Add to Observing WishList: Add the selected object to Observation Planner's Wish List. You can see the Wish List, by selecting the Observation Observation Planner menu item. If the object is already in the Observing WishList, then this item will become Remove Label.

[Solar system objects]

  Add Trail: Add a trail to current Solar system object. A star trail is the continuous path created by the star in the night sky due to the rotation of the Earth. If the object already has a trail, this item will become Remove Trail.

[All]

  Simulate eyepiece view: Eyepiece View feature renders the view through the eyepiece of various telescope types. Firstly, an input dialog is shown, which asks you to select one of the visible FOVs to use as a FOV for the eyepiece view. The user also has the option of trying to determine it from the image (accurate if image has metadata, otherwise it will be random). After you set the FOV, the "Eyepiece Field View" window will pop up. You can easily rotate the view using the "Rotation" slider. You can also flip and invert the view to help match the view through a telescope/camera. "Eyepiece view" tool can help you locate many objects with ease, instead of trying to work with relative positions and relative orientations. This is an important advantage, especially when you are star hopping. Note that for getting best results, time must be synced with current time in &kstars;, and &kstars; must be in horizontal coordinates mode.

[Solar system objects]

  Image Resources: gives a list of image links for current Solar system object. The images are displayed in &kstars; Image Viewer tool. Image Viewer tool allows you to invert the colors and save the image in your computer.

[Solar system objects]

  Information Resources: gives a list of documentation links for current Solar system object. The links are opened in your default browser.

[All objects without Solar system objects]

  Show SDSS Image: download a SDSS (Sloan Digital Sky Survey) image of the object from the Internet, and display it in the Image Viewer tool.

[All objects without Solar system objects]

  Show DSS Image: download a DSS (Digitized Sky Survey) image of the object from the Internet, and display it in the Image Viewer tool.
