From the developer:
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.
