SkySafari isn't just an award-winning iPhone astronomy app - now it's available for Mac OS X, too! SkySafari's interface has been redesigned from scratch for the Mac, using 100% native Cocoa OS X controls.
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 a star chart - it's a celestial travel guide!
Beautifully crafted application. It is possible to enjoy it from different angles: just as a visual feast or in a more deep manner. It has a lot of information about celestial bodies and it is very easy to spend many hours with it.
