Stellarium 1.22.3

 Stellarium

Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. It is being used in planetarium projectors. Just set your coordinates and go.

Stellarium key features:

  • Realistic simulation of the sky, sunrise and sunset
  • Default catalogue of over 600,000 stars
  • Downloadable additional catalogues for up to 210 million stars
  • Catalog data for all New General Catalogue (NGC) objects
  • Images of almost all Messier objects and the Milky Way
  • Artistic illustrations for all 88 modern constellations
  • More than a dozen different cultures with their constellations
  • Solar and lunar eclipse simulation
  • Photorealistic landscapes (more are available on the website)
  • Scripting support with ECMAScript (a few demo scripts are included)
  • Extendable with plug-ins: 8 plug-ins installed by default, including:
  • artificial satellites plug-in (updated from an on-line TLE database)
  • ocular simulation plug-in (shows how objects look like in a given ocular)
  • Solar System editor plug-in (imports comet and asteroid data from the MPC)
  • telescope control plug-in (Meade LX200 and Celestron NexStar compatible)

The major changes of this version:

  • After more than 20 years of development the program is finally accurate enough for historical application.
  • This is the first release based on the Qt6 framework, so the project is safe for future development. These packages are tagged with a version number like 1.22.3.
  • We keep releasing Qt5-based packages for legacy or obsolete systems. This may include many Windows users who have to run ANGLE mode. These packages are tagged with a version number like 0.22.3.
