<abstract>
<para
>&kstars; is a graphical desktop planetarium for KDE. It depicts an accurate simulation of the night sky, including stars, constellations, star clusters, nebulae, galaxies, all planets, the Sun, the Moon, comets and asteroids. You can see the sky as it appears from any location on Earth, on any date. The user interface is highly intuitive and flexible; the display can be panned and zoomed with the mouse, and you can easily identify objects and track their motion across the sky. &kstars; includes many powerful features, yet the interface is clean and simple, and fun to use. </para>

>Introduction</title>

<para
>&kstars; lets you explore the night sky from the comfort of your computer chair. It provides an accurate graphical representation of the night sky for any date, from any location on Earth. The display includes 126,000 stars to 9th magnitude (well below the naked-eye limit), 13,000 deep-sky objects (Messier, NGC, and IC catalogs), all planets, the Sun and Moon, hundreds of comets and asteroids, the Milky Way, 88 constellations, and guide lines such as the <link linkend="ai-cequator"
>celestial equator</link
>, the <link linkend="ai-horizon"
>horizon</link
> and the <link linkend="ai-ecliptic"
>ecliptic</link
>. </para>
<para
>However, &kstars; is more than a simple night-sky simulator. The display provides a compelling interface to a number of tools with which you can learn more about astronomy and the night sky. There is a customised <link linkend="popup-menu"
>popup menu</link
> attached to each displayed object, which displays object-specific information and actions. Hundreds of objects provide links in their popup menus to informative webpages and beautiful images taken by the Hubble Space Telescope and other observatories. </para
><para
>From an object's popup menu, you can open its <link linkend="tool-details"
>Detailed Information Window</link
>, where you can examine positional data about the object, and query a huge treasury of online databases for professional-grade astronomical data and literature references about the object. You can even attach your own internet links, images and text notes, making &kstars; a graphical front-end to your observing logs and your personal astronomical notebook. </para>
<para
>Our <link linkend="tool-calculator"
>Astrocalculator</link
> tool provides direct access to many of the algorithms the program uses behind the scenes, including coordinate converters and time calculators. The <link linkend="tool-aavso"
>AAVSO Lightcurve Generator</link
> tool will download a lightcurve for any of the 6000+ variable stars monitored by the American Association of Variable Star Observers (AAVSO). The lightcurves are generated <quote
>on the fly</quote
> by querying the AAVSO server directly, ensuring that you have the very latest data points. </para>
<para
>You can plan an observing session using our <link linkend="tool-altvstime"
>Altitude vs. Time</link
> tool, which will plot curves representing the Altitude as a function of time for any group of objects. If that is too much detail, we also provide a <link linkend="tool-whatsup"
>What's Up Tonight?</link
> tool that summarises the objects that you will be able to see from your location on any given night. </para>
<para
>&kstars; also provides a <link linkend="tool-solarsys"
>Solar System Viewer</link
>, which shows the current configuration of the major planets in our solar system. There is also a <link linkend="tool-jmoons"
>Jupiter Moons Tool</link
> which shows the positions of Jupiter's four largest moons as a function of time. </para>
<para
>Our primary goal is to make &kstars; an interactive educational tool for learning about astronomy and the night sky. To this end, the &kstars; Handbook includes the <link linkend="astroinfo"
>AstroInfo Project</link
>, a series of short, hyperlinked articles on astronomical topics that can be explored with &kstars;. In addition, &kstars; includes DCOP functions that allow you to <link linkend="tool-scriptbuilder"
>write complex scripts</link
>, making &kstars; a powerful "demo engine" for classroom use or general illustration of astronomical topics. </para>
<para
>You can even control telescopes with &kstars;, using the elegant and powerful <link linkend="indi"
>INDI</link
> hardware interface. &kstars; supports several popular telescopes including Meade's LX200 family and Celestron GPS. Several popular CCD cameras, webcams and computerised focusers are also supported. Simple slew/track commands are integrated directly into the main window's popup menu, and the INDI Control Panel provides full access to all of your telescope's functions. INDI's Client/Server architecture allows for seamless control of any number of <link linkend="indi-kstars-setup"
>local</link
> or <link linkend="indi-remote-control"
>remote</link
> telescopes using a single &kstars; session. </para>
<para
>We are very interested in your feedback; please report bugs or feature requests to the &kstars; development mailing list: <email
>kstars-devel@kde.org</email
>. You can also use the automated bug reporting tool, accessible from the Help menu. </para>
