<p><app>Astrognome</app> has the concept of display themes. A display theme is a ruleset of which planets, aspects and antiscia should the chart view and the table views show.</p>
<p><app>Astrognome</app> has three built in themes:</p>
<p>This is the classic view, used by the early astrologers. It shows planets only up to Saturn, and uses only the Ptolemaic (major) aspects. Also, it doesn’t show any antiscia.</p>
</item>
<item>
<title>No comets</title>
<p>This is the same as Everything, except it doesn’t include the comets and dwarf planets (<app>Astrognome</app>, like most astrologers, treat Pluto as a planet, not a dwarf).</p>
</item>
</terms>
<p>You can choose the right display theme with the display theme chooser above the chart, or change the default display theme in the <link xref="preferences">Preferences</link> dialog.</p>
