SkySafari Pro is for the obsessed kind of observer that wants it all. It contains over 15.3 million stars from the Hubble Guide Star catalog, plus 740,000 galaxies down to 18th magnitude, and over 550,000 solar system objects - including every comet and asteroid ever discovered. Yet it runs just as quickly and smoothly as the basic version.

What's New

Version 1.8:
  • Added 3D models, descriptions, and images of Cassini and Voyager spacecraft, the International Space Station, and Hubble Space Telescope.
  • When you are orbiting an object that itself is orbiting another primary object, SkySafari updates your position so that the primary stays at the same relative position.
  • Chart center longitude/latitude now remembered correctly when more...

An excellent astronomy package that competes with the high end (Voyager and Starry Night) at a budget price. It's one of the few apps that I've come across that works with Location Services on the Mac, the database (whist not as extensive as Voyager or Starry Night) is better than all other packages I've used, and the feature set is extensive. Has a somewhat quirky interface, and auto-reverts to the last screen you used rather than a default ... which I find a tad different from other packages ... but looks like becoming one of my top three in short order.

The latest release of SkySafari Pro for Mac OS X is 1.5, released 9 May 2012. Here are the new features and bug fixes included in this release:

You can now orbit other objects in the solar system! Select an object, then click the new Orbit button in the toolbar to fly into orbit around it. If you select the Sun or any other star, you will fly far above the Sun, where you can see the whole solar system. Once in orbit, swipe to move around. New buttons in the lower left and right corners let you fly toward or away from the planet. When you're ready to return to Earth, click the Home icon at the bottom of the sky chart.
A new super-hi-res Moon map based on imagery from NASA's Lunar Reconnaissance Orbiter has 8x the resolution of any other SkySafari version. When viewing from Earth, the Moon is always a disk with its correct phase. The Moon's dark side now shows faint earthshine, and appears sky-colored in daylight. The sky darkens when solar eclipses take place.
New maps of Earth and Mars have twice the resolution of the previous version. You now see the surfaces of Venus, Earth, and Titan without atmospheres or clouds. Mars's moons Phobos and Deimos are now shaped realistically. Saturn's moon Hyperion tumbles chaotically. Venus - or any other planet - now always shows as a black dot when transiting the Sun. Planet surface grids are drawn more accurately.
Planet and moon surface features are now labelled. So are the landing sites of every spacecraft that humankind has ever sent to any other moon or planet.
Object Info descriptions for the planets and constellations have been rewritten. Learn about the mythology of the planets, the transit of Venus, and total solar eclipses!
Object Info now shows angular separation between the currently selected object and the Sun, the previously-selected object, and the chart center. Object Info also shows opposition, conjunction, eclipse, and transit dates for solar system objects, as well as their apparent motion rates in the sky. Physical ephemeris data are shown for planets and moons.
Asteroid, comet, and satellite orbits have been updated with the latest 2012 data. A few new minor moons of Jupiter, Saturn, and Pluto discovered since 2008 have been added. You can now show orbits of asteroids, comets, and satellites if you select them. Numerous other small solar system computation and graphics bugs are fixed.
You can now search for objects by typing a number without any catalog prefix. Searching for "104" will now find Messier 104, NGC 104, star HR 104, and asteroid (104) Klymene.
You can now use the chart center as the telescope alignment/GoTo target by clicking the target label in the scope control panel. This lets you enter and GoTo to the exact set of coordinates of the chart center, or align on a point like the zenith (+90 altitude).
Improved app icon and splash screen.
