***SkySafari Plus for Mac OS X has been upgraded! This is the old version. To get the latest SkySafari Plus for Mac OS X, search for SkySafari 5 Plus in the Mac App Store!***

SkySafari 4 Plus has all the features in SkySafari 4, and more! Now optimized for Mac OS X, SkySafari Plus adds a hugely expanded database, wired or wireless telescope control, and spaceflight to SkySafari 4.

Like our SkySafari iOS apps, SkySafari for Mac OS X comes in three versions, Basic, Plus and Pro. This version, Plus, 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 lift off into space and leave Earth's surface behind. Click the Orbit button to fly into orbit around other objects in the Solar System, and beyond. Follow eclipses, occultations, and transits in Earth's sky. View the planets and their moons as only NASA space probes have - even indentify every crater on them.

SkySafari 4 Plus adds wired or wireless control for Celestron, Meade, Orion, SkyWatcher, and most other computerized telescopes. It can point your GoTo or "Push-To" telescope anywhere in the sky, using your Mac's built-in WiFi, and our SkyFi or SkyWire serial accessories (sold separately). Plan observing sessions with Observing Lists, log your observations, and share your data 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 builds on the award winning 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: due to Apple policy, there is no discount upgrade path from SkySafari 4 Plus to Pro.)

What's New in Version 4:

*Apple Maps integration: choose your location from a built-in Maps view
*Animated meteor showers, with complete viewing information and spectacular graphics
*New horizon panoramas: Yerba Buena Gardens in downtown San Francisco, Uluru (Ayers Rock) Australia, and the top of Mauna Kea on Hawaii's Big Island or add your own
*New and updated descriptions for hundreds of objects.
*Objects lists are now sortable by name, number, magnitude, RA, Dec, and many other properties
*New Advanced Search options let you find objects using properties other than their name. For example, you can find all objects of a certain type, within a certain constellation, brighter than a certain magnitude, etc.
*New Telescope Equipment settings let you enter a list of all your telescope equipment. Select different combinations of eyepieces and telescopes to display field-of-view automatically. Set up a separate camera and auto-guider FOV. All FOV indicators can be labelled in the sky chart
*Now log observations of objects directly from the Object Info view, or show all your observations of any object at once
*New Variable Stars list, containing the brightest and best-known variables in the sky
*Added descriptions for dozens of asteroids, comets, and satellites; and many images
*Dozens more tweaks, bug fixes, and additions we don't have room to list here!

What's New in Version 4.4.1

1) Fixes incompatibility with Mac OS X 10.6.8 thru 10.8.x.
2) Fixes problem with configuring Celestron Wi-Fi Telescope Access Point mode.

A planetarium program for everyone

In my opinion this is the best planetarium program available. I am running SkySafari 4 Plus on an iMac, a Macbook Air, and a Moto Droid Turbo. It performs beautifully on all three platforms, and it’s operation is very similar on all three platforms (what differences there are is due to the Moto Droid Turbo not having a keyboard). Operation on any platform is very intuitive and should present no problems. SkySafari 4 Plus also puts little demand on resources on either platform, it has low memory usage, uses little processor time, and uses little storage space.

I have run SkySafari 4 Plus on all three platforms, connected via WiFi to my iOptron MiniTower Pro mount (using the SkyFi USB module) and all platforms are able to control the mount, slew to objects, and center the object in the camera or eyepiece. Each platform was able to do all that was asked of it, and performed admirably, even over a considerable distance.

I would not hesitate to recommend SkySafari 4 Plus to anyone, it is a real bargain.


THough I like the database and the ability to set up lists, it definitely still has issues. I was thrilled that they fixed the bugs for use on Celestron wifi but….NOT. Once it finally connected, it wouldnt align properly. Once I finally got it to align manually, when using ‘go to’ it would send the telescope it a completely opposite and random direction. Even while trying too simply manually move it over to an adjoing star, it would spin anywhere from 90 to 180 degrees and point at nothing. Very frustrating. Tried to center in on Jupiter at one point and it directed itself to the zenith high despite Jupiter being in a completely different spot. Still has bugs to work out guys. Dont waste your time if you are trying to hook into and control your Celestron. Great for database only and getting your Messier numbers or NGC.

No Celestron SkyQ support

Had high hopes that this version would control Celestron via SkyQ Link 2 WiFi adapter since the description say “Celestron WiFi support.” Not the case. That feature only works with the Windows version. To control via WiFi you need SkySafari’s own branded “SkyFi” module. Despite there being options in the telescope settings for Celestron WiFi that function does not work with SkyQ. (I have no intentions of ever buying SkyFi, it’s too big to be hanging off my mount and requires external power and is too expensive). Developer said there’s no Celestron SkyQ support planned because Celestron hasn’t requested or paid for the OS X version of SkyQ to work. Guess there’s not enough Mac astronomers out there, such a pitty and waste of money. Just use Stellarium instead, it’s free and does everything SkySafari does.
