Spaceflight has never been so easy! With SkySafari 3 Plus, you can follow events like eclipses and transits in Earth's sky - or from anywhere else in the galaxy!
Like our SkySafari iPhone apps, SkySafari for Mac OS X comes in three versions. This version - SkySafari Plus - is the intermediate one. It adds a hugely expanded database, wired or wireless telescope control - and the ability to fly into orbit around other Solar System objects and nearby stars - to our basic version.
SkySafari Plus shows you 2.5 million stars, and 31,000 deep sky objects - including the entire NGC/IC catalog. It shows the Solar System's major planets and moons using NASA spacecraft imagery, and includes over 4,000 asteroids, comets, and satellites with updateable orbits. It can point your GoTo or "Push-To" telescope anywhere in the sky, using your Mac's built-in WiFi, or a USB-to-serial adapter.
SkySafari Plus 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 1100 encyclopedic descriptions of the constellations, stars, and planets written by professional astronomers. And it contains over 800 images from NASA space missions, the Hubble Space Telescope, and the world's foremost astro-photographers.
SkySafari Plus 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 Plus 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 a celestial travel guide!
