Voyager for MacOverview
Voyager for Mac is the advanced version of our software, designed for the serious astronomy enthusiast. View the heavens on your computer from any place on Earth, in the Solar System, or beyond. Witness celestial events thousands of years in the past or future. See millions of stars, clusters, nebulae, and galaxies visible only through powerful telescopes. Drive your computer-controlled telescope to the objects displayed on your computer screen.
New Calendar Systems
Voyager 4.5 includes support for the Hebrew, Islamic, Persian, Indian, and Mayan calendars. Find the dates and times of new moons that mark the start of Islamic months, or determine the date that the Mayan calendar predicts the "end of the world".
A Million-Year Timespan
Voyager 4.5 accurately models the precession of the Earth's axis and the motions of the stars back to the Dawn of humanity. Voyager 4.5 extrapolates lunar and planetary positions forward and backward realistically over 500,000 years from the present - and for times within 10,000 years of the present, Voyager 4.5's lunar and planetary positions will match JPL's precisely.

New Object Descriptions
In addition to their numerical data, Voyager 4.5 now includes textual, plain-English descriptions for hundreds of planets, moons, stars, clusters, nebulae, and galaxies, developed in conjunction with professor Jim Kaler of the University of Illinois. Learn the history and mythology of the Constellations. Discover "fun facts" about the objects you can see in the night sky!
