StellaNavigator, the astronomical simulation software, is finally available on mobile!
StellaNavigator is a purely Japanese-developed astronomical simulation software that has achieved de facto standard status in Japan.
Boasting astronomical calculations capable of accurately simulating solar eclipses, lunar eclipses, and stellar occultations—which require high precision—as well as highly reliable reprodibility that extends even to the field of historical astronomy, it has met the diverse needs of a wide range of users, from casual stargazers to those engaged in astrophotography and observation, and even to astronomy professionals such as astronomers and planetarium presenters.
Because StellaNavigator can accurately reproduce a wide variety of astronomical phenomena, it provides powerful support for your astronomical pursuits in various situations—from simply gazing at the night sky to learning about and enjoying the universe, planning astrophotography sessions, and even controlling a telescope in the field.
