Introduction

SkySafari is a celestial travel guide, designed to help you explore the night sky. It is a powerful planetarium program that fits in your pocket, with thousands of stars, planets, and other objects at your fingertips. And SkySafari's Plus and Pro versions can turn your iPhone, iPad, or iPod Touch into a 21st-century telescope controller.

SkySafari contains a database with hundreds of thousands - or millions - of stars. It displays the planets and moons of the Solar System using NASA spacecraft imagery, and includes hundreds - or thousands - of asteroids, comets, and artificial satellites.

SkySafari is able to accurately depict these objects in the sky from any location on Earth, and at any time in the past, present, or future. In addition, SkySafari includes informative, plain-English descriptions of the constellations, planets, moons, stars, and deep sky objects. It contains hundreds of images from NASA space missions, the Hubble Space Telescope, and the world's foremost amateur and professional astro-photographers.

SkySafari now includes push notifications. With these, you can automatically receive notifications of celestial events, like eclipses and transits, discoveries of new comets, supernovae, or other product-related announcements.

SkySafari supports Apple's iPad VGA adapter. With this adapter connected, your iPad can mirror SkySafari's displays on an external monitor - or a big-screen TV!

SkySafari's simple user interface, combined with its ability to control your GoTo telescope, makes it an invaluable tool for exploring the night sky. We hope you enjoy using SkySafari.

SkySafari Plus and Pro

SkySafari comes in three versions:

SkySafari's basic version contains 120,000 stars to 8th magnitude, and the 220 best-known star clusters, nebulae, and galaxies in the sky (the Messier and Caldwell catalogs). It includes images of most Messier objects, and nearly 500 object descriptions.

SkySafari Plus includes 2.5 million stars to 12th magnitude, and 30,000 deep sky objects, including the entire NGC and IC catalogs. SkySafari Plus also contains more than 300 color images of the best known nebulae and galaxies from the Digitized Sky Survey, and more than 1000 object descriptions.

SkySafari Plus can also point your computer-controlled GoTo telescope anywhere in the sky. To do this, you'll need either our SkyWire serial cable accessory, or a Wi-Fi-to-serial adapter like our SkyFi or Orion's StarSeek Wi-Fi adapter. See the Southern Stars website for more details.

SkySafari Plus also offers higher precision, more sky charting options, the ability to update asteroid/comet/spacecraft data from the internet, observation planning and logging capabilites, and other features of interest to serious observers.

SkySafari Pro contains the same features and functions as SkySafari Plus. But it adds a vastly-expanded database of 15 million stars to 15th magnitude from the Hubble Guide Star Catalog; a deep sky database of 740,000 objects to 18th magnitude from the Principal Galaxy Catalog; and a solar system database of over 550,000 objects - including every known planet, moon, asteroid, and comet.
