Hallo Northern Sky: Mapping Stars and Constellations for Beginners

Hallo Northern Sky (HNSKY) is an exceptional, semi-professional planetarium program, but whether it is the “best” depends entirely on your needs. For telescope control and deep-sky charting, it is one of the top freeware choices available. However, for realistic 3D visual rendering and casual sky gazing, Stellarium remains the undisputed community favorite. Where HNSKY Excels HNSKY download | SourceForge.net
