Reviews

"This app does everything a person who is a visual observer, binocular user, or owner of a small telescope could want. It's easy to customize, the various menus and options are clearly laid out, and the look of the app is terrific. It also includes a list of interesting objects that can be seen on any night the user chooses -- stars, messier objects, planets, etc. The develper and his staff also are prompt to answer e-mail so there is actually support after purchase!"

"I like this app for its simplicity of use. It hides the advanced options for a fun clean view of the night sky. It is very similar to the iOS version of SkySafari, so I didn't have to waste lots of time re-understanding and re-learning this app. Good work!"

SkySafari for Mac OS X

This is the basic version of SkySafari. It shows you 46,000 stars, plus 220 of the best-known star clusters, nebulae, and galaxies in the sky. It displays the Solar System's major planets and moons using NASA spacecraft imager. It includes the best-known asteroids and comets, and the 150 (or so) satellites bright enough to see with your unaided eyes.

SkySafari accurately shows you the sky from any place on Earth, at any time up to one hundred years in the past or future. It includes encyclopedic descriptions of the constellations, stars, and planets written by professional astronomers. And it contains hundreds of images from NASA space missions, the Hubble Space Telescope, and the world's foremost astro-photographers.

SkySafari introduces you to the night sky -
from anywhere on Earth, at any time.

The constellations Sagittarius and Scorpius (highlited)

and experience the science behind them.

SkySafari has a "Night Vision" mode to preserve your dark adaptation as you're exploring the night sky. The Time Flow feature lets you animate the night sky using simple VCR controls - follow the motion of the stars and planets as SkySafari compresses days, months, and years into a few seconds.
