SkySafari is a powerful planetarium that fits in your pocket. It puts thousands of stars, planets, and other objects at your fingertips. With SkySafari Plus and Pro, you can fly into orbit around other planets and stars, and control computerized telescopes wirelessly.

    SkySafari's basic version includes everything you need to get started learning the night sky: 120,000 stars; over 200 star clusters, nebulae, and galaxies; all major planets and moons, and dozens of asteroids, comets, and satellites - including the ISS. Here's what you can do with SkySafari:

    SkySafari now supports Apple Watch, putting the Sun, Moon, Planets, and more on your wrist!

    • Simulate the night sky from anywhere on planet Earth, up to 100 years in the past or future.

    • Search for celestial objects, and locate them in the sky using your iDevice's built-in motion hardware.

    • Animate transits, conjunctions, eclipses, and other events with SkySafari's Time controls.

    • Explore the sky with Night Vision turned on, and preserve your eyesight after dark.

    • Learn the history, mythology, and science of the heavens from SkySafari's hundreds of object descriptions.

    • Browse hundreds of astronomical photographs and NASA spacecraft images. Stay up-to-date with SkyWeek, Sky & Telescope's mobile portal to all major sky events for every day of the week. Miss nothing!

    All this is built into SkySafari - you don't need an internet connection to use it. SkySafari Plus and Pro add even more - but the basic version is everything the casual stargazer will ever want. (Please note: there is no discount upgrade path to SkySafari Plus or Pro.)

    SkySafari Plus

    SkySafari Plus is everything in SkySafari, plus more. Plus adds a hugely expanded database, wired or wireless telescope control, observing tools, and spaceflight to SkySafari.

    The Plus version includes 2.5 million stars, 31,000 deep sky objects, the Solar System's major planets and moons, and over 4,000 updatable asteroids, comets, and satellites. Simulate the sky from any place in the Solar System, up to 10,000 years in the past or future. Expand your astronomical knowledge with over 1500 encyclopedic descriptions of the constellations, stars, and planets. Enjoy more than 800 images from NASA space missions, the Hubble Space Telescope, and the world's foremost astro-photographers.

    With SkySafari Plus, you can leave Earth's surface behind. Tap the Orbit button to fly into orbit around other objects in the Solar System, and beyond it. Follow eclipses, occultations, and transits in Earth's sky - and beyond! View the planets and their moons as only NASA space probes have - even label every crater on them.

    SkySafari Plus adds wired or wireless control for Celestron, Meade, Orion, SkyWatcher, and many other computerized telescopes. It can point your GoTo or "Push-To" telescope anywhere in the sky, using your iPhone/iPad/iPod's built-in WiFi, and our SkyFi or SkyWire serial accessories (sold separately). Plan observing sessions with Observing Lists, log your observations into them, and share them with friends. More astronomers use SkySafari for telescope control than any other app!

    SkySafari Pro

    SkySafari Pro has the largest database of any astronomy app, period. It contains everything in SkySafari Plus, and adds over 1.2 GB of data, including 25 million stars from both UCAC5 Star catalog, over 740,000 galaxies down to 18th magnitude, and over 630,000 solar system objects - including every comet and asteroid ever discovered. It simulates the view from anywhere in the solar system - or beyond it - at up to a million years in the past or future.

    SkySafari Pro includes NASA's latest Moon and Mars maps, with 8x the resolution of any other SkySafari version. It's an astronomical encyclopedia, with over 1500 encyclopedic descriptions of the constellations, stars, and planets written by professionals. And it includes 800 images from NASA space missions, the Hubble Space Telescope, and the world's foremost astro-photographers - now in breathtaking high definition on your iPad!

    SkySafari Pro will revolutionize your astronomical viewing experience, and replace desktop astronomy software costing ten times more. If you're serious about astronomy, it's a deal you can't afford to miss.
