It can point your GoTo or "Push-To" telescope anywhere in the sky, using your Android device's built-in bluetooth or WiFi, and our SkyFi wireless or Starry Night BlueStar bluetooth serial adapter.SkySafari accurately shows you the sky from any place on Earth, at any time up to 10,000 years in the past or future.

Our deep sky database contains thousands of NGC/IC objects, not just the 110-object Messier catalog.Our apps contain hundreds of built-in images, and thousands of object descriptions, written by professional astronomers. Google SkyMap gives you Wikipedia links - which don't do much good out in the field, away from Wi-Fi or data network connections.Our Plus and Pro versions can control telescopes; Google SkyMap cannot. Google SkyMap can't reproduce basic astronomical phenomena like lunar eclipses and Jovian satellite shadow transits. Our apps were developed by passionate astronomers with a penchant for quality and accuracy - we make a living from our products!TROUBLESHOOTING AND PERFORMANCE TIPSIs SkySafari Plus having trouble downloading its data files?
