It's loaded with over 100,000 stars, the planets, Sun, Moon, Milky Way, constellations, lines of right ascension and declination, the ecliptic, and more than 500 of the most important deep sky objects.

The optional night vision mode ensures you get the most out of your outdoor stargazing sessions.
