0223 <para>
0224 &kstars; is free, open source, cross-platform Astronomy Software.
0225 
0226 It provides an accurate graphical simulation of the night sky, from any location on Earth, at any date and time. The display includes up to 100 million stars, 13,000 deep-sky objects,all 8 planets, the Sun and Moon, and thousands of comets, asteroids, supernovae, and satellites.
0227 
0228 For students and teachers, it supports adjustable simulation speeds in order to view phenomena that happen over long timescales, the &kstars; Astrocalculator to predict conjunctions, and many common astronomical calculations. For the amateur astronomer, it provides an observation planner, a sky calendar tool, and an FOV editor to calculate field of view of equipment and display them. Find out interesting objects in the <quote>What's up Tonight</quote> tool, plot altitude vs. time graphs for any object, print high-quality sky charts, and gain access to lots of information and resources to help you explore the universe!
0229 
0230 HiPS all-sky progressive overlay provide stunning views from numerous surveys spanning the whole electromagnetic spectrum.
0231 
0232 Included with &kstars; is Ekos astrophotography suite, a complete astrophotography solution that can control all INDI devices including numerous telescopes, CCDs, DSLRs, focusers, filters, and a lot more. Ekos supports highly accurate tracking using online and offline astrometry solver, autofocus and autoguiding capabilities, and capture of single or multiple images using the powerful built in sequence manager.

0248 <para>
0249 &kstars; lets you explore the night sky from the comfort of your computer chair.  It provides an accurate graphical
0250 representation of the night sky for any date, from any location on
0251 Earth.  The display includes 126,000 stars to 9th magnitude (100 million with addon catalogs), 13,000 deep-sky objects (Messier, NGC, and IC catalogs), all planets, the Sun and Moon, hundreds of comets and
0252 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>.
0253 </para>
0254 <para>
0255 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
0256 a context-sensitive <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
0257 popup menus to informative web pages and beautiful images taken by the Hubble Space Telescope and other observatories.
0258 </para><para>
0259 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.
0260 </para>
0261 <para>
0262 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.
0263 </para>
0264 <para>
0265 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 summarizes the objects that you will be able to see from your location on any given night. You can add your favorite objects to your
0266 observing wish-list using the <link linkend="tool-obsplanner">Observation Planner</link> tool, which allows you to plan your observation sessions professionally. To see how object appears in the eyepiece under different telescopes and field of views, use the <link linkend="tool-eyepieceview">Simulate Eyepiece View</link> tool to render a simulated view of what you see.
0267 </para>
0268 <para>
0269 &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
0270 linkend="tool-jmoons">Jupiter Moons Tool</link> which shows the positions of Jupiter's four largest moons as a function of time.
0271 </para>
0272 <para>
0273 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
0274 Project</link>, a series of short, hyperlinked articles on astronomical topics that can be explored with &kstars;.  In addition, &kstars;
0275 includes &DBus; functions that allow you to <link linkend="tool-scriptbuilder">write complex scripts</link>, making &kstars; a powerful <quote>demo engine</quote> for classroom use or general illustration of
0276 astronomical topics. Furthermore, any 3rd party tool or language with support of &DBus; can be used to write powerful scripts using <ulink url="https://api.kde.org/appscomplete-api/kstars-apidocs/kstars/html/classKStars.html">&kstars; &DBus; API</ulink>.
0277 </para>
0278 <para>
0279 Enable <link linkend="hips">HiPS all-sky progressive overlay</link> to fetch high-resolution images and display them directly in the sky map. You can select from numerous catalogs compiled from different earth and space based missions.
0280 This features requires a fast internet connection in order to download the images. The images are cached locally to reduce bandwidth. You can optimize the caching options to best balance between disk space versus bandwidth.
0281 </para>
0282 <para>
0283 However, &kstars; is not just for students.  You can control telescopes and cameras with &kstars;, using the elegant and powerful <link linkend="indi">INDI</link> protocol.  &kstars; supports several popular
0284 telescopes including Meade's LX200 family and Celestron GPS.  Several popular CCD cameras, webcams, and computerized focusers are also supported.  Simple slew/track commands are integrated directly into the main window's
0285 popup menu, and the INDI Control Panel provides full access to all of your telescope's functions. INDI's Client/Server
0286 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
0287 &kstars; session. For advanced users, &kstars; provides Ekos, a complete astrophotography suite for Linux. <ulink url="https://indilib.org/about/ekos.html">Ekos</ulink> is based on a modular extensible framework to perform common astrophotography tasks. This includes highly accurate GOTOs using astrometry solver, ability to measure and correct polar alignment errors , auto-focus and auto-guide capabilities,
0288 and capture of single or stack of images with filter wheel support.
