SkySafari 4 Plus is everything in SkySafari 4, plus more. Now completely rebuilt for Mac OS X, Plus adds a hugely expanded database, wired or wireless telescope control, and spaceflight to SkySafari 4.
Like our SkySafari iPhone apps, SkySafari for Mac OS X comes in three versions. This version includes 2.5 million stars, 31,000 deep sky objects, the Solar System's major planets and moons, and over 4,000 updatable asteroids, comets, and satellites. Simulate the sky from any place in the Solar System, up to 10,000 years in the past or future. Expand your astronomical knowledge with over 1500 encyclopedic descriptions of the constellations, stars, and planets. Enjoy more than 800 images from NASA space missions, the Hubble Space Telescope, and the world's foremost astro-photographers.
With SkySafari 4 Plus, you can leave Earth's surface behind. Click the Orbit button to fly into orbit around other objects in the Solar System, and beyond it. Follow eclipses, occultations, and transits in Earth's sky - and beyond! View the planets and their moons as only NASA space probes have - even label every crater on them.
SkySafari 4 Plus adds wired or wireless control for Celestron, Meade, Orion, SkyWatcher, and many other computerized telescopes. It can point your GoTo or "Push-To" telescope anywhere in the sky, using your iPhone/iPad/iPod's built-in WiFi, and our SkyFi or SkyWire serial accessories (sold separately). Plan observing sessions with Observing Lists, log your observations into them, and share them with friends. More astronomers use SkySafari for telescope control than any other app!
SkySafari Plus takes advantage of Apple's latest Mac OS X features. It understands multitouch gestures and supports full-screen mode. Its responsive, fluid interface borrows from the best of SkySafari for iOS. SkySafari's streamlined interface puts the universe at your fingertips. It's hard to believe there's even more in SkySafari 4 Pro - but Plus will keep anyone with a small backyard telescope busy for years. (Please note: there is no discount upgrade path from SkySafari 4 Plus to Pro.)
SkySafari Plus and Pro can point your GoTo or "Push-To" telescope anywhere in the sky, using either:
Connected by either of these methods, SkySafari Plus and Pro can control the following GoTo telescopes:
