Stellarium is a free open source planetarium for your computer. Stellarium renders 3D photo-realistic skies in real time with OpenGL. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. Stellarium displays stars, constellations, planets, nebulas and others things like ground, landscape, atmosphere, etc. There is an ability to add new solar system objects from online resources. You can add your own deep sky objects, landscapes, constellation images, scripts. The plugin system adds artifical satellites, ocular simulation, telescope configuration and more. It is being used in planetarium projectors. Just set your coordinates and go. Stellarium is available for Linux/Unix, Windows and Mac OS X. - default catalogue of over 600,000 stars - extra catalogues with more than 210 million stars - asterisms and illustrations of the constellations - constellations for eleven different cultures - images of nebulae (full Messier catalogue) - realistic Milky Way - very realistic atmosphere, sunrise and sunset - the planets and their satellites - a powerful zoom - time control - multilingual interface - fisheye projection for planetarium domes - spheric mirror projection for your own low-cost dome - all new graphical interface and extensive keyboard control - telescope control - equatorial and azimuthal grids - star twinkling - shooting stars - eclipse simulation - skinnable landscapes, now with spheric panorama projection Changes in Stellarium 0.14.0: * Stellarium 0.14.0 brings a big leap forward in astronomical accuracy for historical applications: – Precession now follows the IAU2006 model in the long-time version from Vondrák et al. 2011. – Nutation is applied (IAU2000B solution). Given that nobody has observed it without telescope and the model does not give limits of applicability, we limit its application to 1500..2500 – Application of DeltaT has been simplified and made a bit more intuitive. * We now dare to add another coordinate system: Ecliptic coordinates of date. * We can therefore now show that planetary positions given by the commonly used solution VSOP87 is applicable to -4000..+8000 only, and its use outside this range will give somewhat artificial results. There is more to follow in future versions. * The other big addition is a greatly improved collection of DSO data with lots of possibilities in a new GUI tab to select for object type and/or catalog. In total, 15 catalogs are now built-in! * Also the Meteor Shower, Satellites, Telescope Control and 3D Sceneries plugins have been improved. * Landscapes can have switchable labels, so you can e.g. indicate mountain peaks. * In total 83 bugs and wishlist items were fixed or at least decided. Install notes: - The launching of the "Stellarium 0.14.0 Portable to PortableApps.exe" select where to drop off a folder with the program - the default is the desktop - After unpacking, run the application through "StellariumPortable.exe"
