It is loved by beginners learning the constellations and by serious observers planning an evening with a telescope outside.

System Requirements
You need a Mac with graphics that support OpenGL and a current version of macOS. Extra star catalogues can be fetched from inside the app when you want more detail, so an internet connection helps at first, though the main sky works offline.

Can it show the sky from my town?
