SkySafari isn't just an award-winning iPhone astronomy app any more. SkySafari's interface has been redesigned from scratch for the Mac, using 100% native Cocoa OS X controls. SkySafari's iOS OpenGL astronomy engine soars on the Mac, and a full-sized monitor, mouse, and keyboard open up a universe of new possibilities.
Like the SkySafari iPhone apps, SkySafari for Mac OS X comes in three versions. This is the basic version. It shows you 46,000 stars, plus 220 of the best-known star clusters, nebulae, and galaxies in the sky. It displays the Solar System's major planets and moons using NASA spacecraft imagery, and includes the best-known asteroids and comets.
SkySafari accurately shows you the sky from any place on Earth, at any time up to one million years in the past or future. It includes encyclopedic descriptions of the constellations, stars, and planets written by professional astronomers. And it contains hundreds of images from NASA space missions, the Hubble Space Telescope, and the world's foremost astro-photographers.
SkySafari has a "Night" button to preserve your dark adaptation as you're exploring the night sky. The Time Flow feature lets you animate the night sky using simple VCR controls - follow the motion of the stars and planets as SkySafari compresses days, months, and years into a few seconds.
SkySafari takes advantage of Apple's latest Mac OS X features. It understands multitouch gestures on Macs with multitouch trackpads, and supports OS X 10.7 (Lion) full-screen mode. And its responsive, fluid interface borrows from the best aspects of SkySafari for iPhone. SkySafari for Mac OS X truly brings astronomy software into the 21st century. It's more than just a star chart - it's your celestial travel guide!
1) Fixed many small accuracy problems in importing orbit data from the Minor Planet Center. Orbital elements are now stored to 64 bits of precision.
2) Fixed failure to draw many bright stars when the magnitude limit was set below 3.
3) Object Info for satellites now shows satellite latitude, longitude, altitude, and velocity.
