The 0036 objects are organized into type categories. Select an object type 0037 in the box labeled <guilabel>Select a category:</guilabel>, and all 0038 objects of that type which are above the horizon on the selected 0039 night will be displayed in the box labeled <guilabel>Matching 0040 objects:</guilabel>. For example, in the screenshot, the 0041 <guilabel>Planets</guilabel> category has been selected, and three 0042 planets which are up on the selected night are displayed (Mars, 0043 Jupiter and Saturn). When an object in the list is selected, 0044 its rise, set and transit times are displayed in the lower-right 0045 panel (&ie; Mars rises at 17:13, transits at 21:46 and sets at 02:16). 0046 In addition, you can press the <guibutton>Object Details...</guibutton> 0047 button to open the <link linkend="tool-details">Object Details window</link> 0048 for that object. 0049 </para> 0050 <para> 0051 By default, the WUT will display objects which are above the horizon 0052 between sunset and midnight (&ie; <quote>in the evening</quote>). 0053 You can choose to show objects which are up between midnight and dawn 0054 (<quote>in the morning</quote>), or between dusk and dawn (<quote>any 0055 time tonight</quote>) using the combobox near the top of the window. 0056 You can also choose to see only those objects that are brighter than a 0057 magnitude by setting a minimum magnitude using the <guilabel>Show objects 0058 brighter than magnitude:</guilabel> spinbox. You may center the selected object 0059 in the Sky Map or add it to Wish List by pressing the 0060 <guibutton>Center Object</guibutton> or <guibutton>Add to List</guibutton> button. 0061 </para> 0062 </sect1> 0063
