Stellarium Mobile Quick Start Guide Version 1.0.0 firstname.lastname@example.org Introduction Stellarium Mobile is a planetarium application for your Nokia N900. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. It features an intuitive touch-screen-friendly user interface and allows GPS positioning and accelerometers control. This project is based on a highly-optimized version of the desktop software Stellarium and is developed by its original creator. Overview Once started the program will display the sky at the current time and current location. Basic navigation is achieved by panning the view with your fingers, and zooming in and out using the camera zoom buttons. The two most useful GUI elements are the Quick Bar which can be opened by tapping on the bottom right corner button, and the Time Bar which can be opened by tapping on the date in the bottom left corner. The Quick Bar It gives quick access to the most useful buttons for displaying/hiding sky elements, searching object, activating accelerometers control or for displaying/hiding the main maemo menu. Keeping the finger pressed on a button will display its function. The Time Bar It contains buttons for reverse and fast forwarding in time. When displayed, it also activates the time dragging mode, i.e. dragging the sky with the finger, will "move the time" instead of moving the direction of view. This way of interacting with time gives you the amazing feeling of controlling the earth rotation on his axis with just one finger! The Main Maemo Menu and Projection dialogs). It is accessed by pressing the button from the Quick Bar, and opening the standard maemo menu. It provides access to settings such as changing the landscape images (Landscapes dialog), selecting other constellations sky cultures (Starlore dialog), or for setting various sky and projection parameters (Sky, Marking Time and Location For an astronomy application, time and location are crucial parameters which completely determine how the sky will look like for a given observer. At start-up, the default behavior of the program is to use current time, and to try to obtain your current location using the GPS or network positioning. However, if you are starting Stellarium Mobile during daytime, the sky simulation will automatically fast forward in time until night comes. Both these default behaviors can be changed in the Location and Time dialogs from the main maemo menu. Object Selection Tapping on an object in the sky will display a context menu in the top left corner, allowing to center the view on the object, automatically zoom in or out, and display information about its position or magnitude (brightness). To unselect the object, tap on the object's name. More Info Please refer to www.stellarium-mobile.org for more information about this application.
