Screenshot #1 In this screenshot we can see a typical session with Encyclopedia Galactica. The main area is occupied by a sky area map which is centered on Gemini. All the labels, lines objects, etc. are fully customizable. In addition, we can see in the right side the "Reference Card" for Jupiter. This window has appeared by clicking on the Jupiter icon which is approximately centered in the map. The Reference Card provides all the basic data about the object, and contains a number of icons at the bottom which allow to trigger different actions related to the object (creating a new map centered on it, showing the visibility graphs, viewing the available images, adding a new image, adding to the observing list and accessing notes and information). Between the Reference Card and the map lies the Navigator window. The content of this window is customizable, and allows you to have at the click of the mouse the most used functions that affect the map's appearance. Laying underneath all the windows there is a Jupiter image that is stored within Encyclopedia Galactica's directory structure, and about which you can maintain a description.
Screenshot #2 This screenshot shows four of the tools available in Encyclopedia Galactica. On the left side you can see the Jupiter and Saturn satellites tool, which allows to locate and identify the satellites of these planets. The top right window shows the Orrery tool, which renders a three dimensional view of the solar system. On the lower right side you can see the groundtracks of the HST and the ISS satellites, a plot that can be generated from the satellite visibility tool.
Screenshot #3 Encyclopedia Galactica's toolset includes a Moon calendar, in which you can check not only the Moon's phase, but also obtain on a daily basis other interesting information, such as the rise and set times, and a Moon feature locator, on which you can locate the main lunar features.
