SkySafari 4 Pro

Now for Mac OS X! SkySafari 4 Pro has an absolutely huge database of astronomical objects. It contains everything in SkySafari 4 Plus, and adds over 1.2 GB of data, including 25 million stars from both Hubble Guide Star catalogs, over 740,000 galaxies down to 18th magnitude, and over 630,000 solar system objects – including every comet and asteroid ever discovered. It simulates the view from anywhere in the solar system – or beyond it – at up to a million years in the past or future.

SkySafari 4 Pro includes NASA’s latest Moon and Mars maps, with 8x the resolution of any other SkySafari version. It’s an astronomical encyclopedia, with over 1500 encyclopedic descriptions of the constellations, stars, and planets written by professionals. And it includes 800 images from NASA space missions, the Hubble Space Telescope, and the world’s foremost astro-photographers – now in breathtaking high definition on your Mac!

SkySafari 4 Pro 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.

All this is built into SkySafari 4 Pro – you don’t need an internet connection to use it. SkySafari 4 Pro will revolutionize your astronomical viewing experience. If you’re serious about astronomy, it’s a deal you can’t afford to miss.

If you’ve used SkySafari Pro before, here’s 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 under Search 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 hundreds of small moons, asteroids, comets, satellites; and many images.
* All full screen images in Object Info now include hi-res versions for the iPad.
* Database now contains Guide Star Catalog 2.x stars to magnitude 15 – total 25 million (up from 15 million in SkySafari 3 Pro).
* Database now includes the complete General Catalog of Variable Stars and Washington Double Star catalogs.
* Dozens more tweaks, bug fixes, and additions we don’t have room to list here!

1) Social sharing! Share screen shots on Facebook, Twitter, and your other favorite social media sites using a new share icon in the lower right corner of the sky chart window.
2) New option in Settings -> Constellations to show zodiac constellations only.
3) New option in Settings -> Solar System to show planet rotational axes.
4) New option in Settings -> Solar System to magnify moons and planets by up to 100x and 10,000x, respectively.
5) New option in Settings -> Solar System to show outlines of the Earth’s and Moon’s umbral and penumbral shadows. Useful for simulating solar and lunar eclipses.

6) New option in Settings -> Milky Way to show the sky background in other wavelengths: infra-red, radio, microwave, X-ray, and gamma ray.
7) New maps of Saturn’s moons Mimas, Enceladus, Tethys, Dione, Rhea, Iapetus; new map of Neptune’s moon Triton.
8) New 3D models and trajectory data for the Voyager, Pioneer, Galileo, Cassini, Dawn, and New Horizons spacecraft.
9) Slightly modified formula used to compute size of Earth’s shadow to be more consistent with NASA’s lunar eclipse predictions.
10) New "measurement mode" to measure distance between objects. Double-tap the screen to show a line from the selected object to any other object or point on screen, labelled with angular distance (in degrees) and physical distance (in AU or light years) between objects.
11) Improved formula for predicting position and timings of Jupiter’s Great Red Spot, based on 2013 – 2014 observations.
12) Now possible to turn off Sun glow by turning off planet atmospheres (in Settings -> Solar System).
13) Support for directional move command on ServoCAT telescopes (requires ServoCAT firmware version 62.P or later).
