Stellarium 0.15.0 recently released, 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. Stellarium 0.15.0 is based on Qt5.6. Starting with this version, some graphics cards have been blacklisted by Qt and are automatically forced to use ANGLE on Windows. A major internal change with the StelProperty system was introduced. This allows simpler access to internal variables and therefore more ways of operation.
