Add other objects using the "Add" button (useful feature when visualizing close conjunctions between objects)
Choose the date and time for which you want to compute the position
Choose your geographical location in order to see the precise position of the objects with respect to the horizon and accurate times for rise, transit and set
Pan the sky chart by dragging it, zoom in or out using the mose wheel or the slider
Take screenshots using the 'p' key (image opens in a popup window)
