SkyVoyager is our "Pro" iPhone astronomy app - if you are a beginner, or looking for something simpler, you might want to check out SkyGazer, our "Lite" version.
SkyVoyager is a powerful astronomy program, with a database of 300,000 stars and 30,000 deep sky objects. It renders the planets and moons in detail, using NASA mission imagery.
SkyVoyager includes an Expansion Pack with 2.5 million stars, and more than 300 color deep sky object images, dramatically increasing the realism and usefulness of your sky charts. This is an optional $5 in-app purchase, available in the Settings.
SkyVoyager is a planetarium that precisely shows the sky from any location on Earth, at any time in the past or future. It contains informative descriptions of the planets, stars, and constellations; and includes hundreds of images from both NASA and leading astro-photographers.
If you have an iPhone 3G S with a compass, SkyVoyager can show you the sky in same the direction that you're holding your phone. Shake the phone to activate its compass and/or accelerometer - now you can identify stars and planets by holding your phone next to them! You can find any object in the sky by following an arrow that points in its direction. (Go to Settings -> Coordinates to enable Compass support.)
SkyVoyager contains interface themes that let you change the look-and-feel of the app, including a much-improved "Night Vision" theme that preserves your dark adaption 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 SkyVoyager compresses days, months, and years into a few seconds.
If you have a computer-controlled telescope, SkyVoyager can use your iPhone or iPod's WiFi to point it in the sky. SkyVoyager's simple user interface, and its ability to wirelessly control your scope, make it an invaluable tool for exploring the heavens.
1. In the main Search view, for both object lists and search results, objects below the horizon are displayed in a darker color, so that you can quickly tell "what's up" versus what's below the horizon.
2. Asterisms (like the Big Dipper) and their names can now be displayed in gold, to distinguish them from constellation lines, which are shown in purple. Galaxy ovals are now flipped correctly when the chart is displayed with the Flip Horizontal option turned on, in the Settings -> Coordinates view.
3. If you tap the "Purchase Expansion Pack" button, but have already purchased the expansion pack, you'll get a message saying so immediately, rather than at the end of another in-app purchase. Star data is now stored more efficiently, reducing the total app size by about 10%.
4. The most current asteroid orbits are now imported from the Minor Planet Center. Iridium, GPS, and geosynchronous satellites are also now imported from Celestrak.com. Asteroid, comet, and satellite updates are now done in a background thread, so the app doesn't appear to freeze up while data is being imported.
5. After centering an object, then turning on the compass/altimeter (either by shaking the iPhone/iPod Touch, or from Settings) the chart now follows the compass/altimeter, instead of remaining locked on the centered object.
6. In the Object Info view for the Moon, SkyVoyager now displays the date and time of the next moon phase event after the current date. in the Object Info view for stars, radial velocities are now displayed correctly - previously they were too small by factor of 3.26.
7. Connecting to a telescope now happens in a background thread, so the app doesn't appear to freeze while the connection attempt is in progress. When re-connecting to a telescope after waking up from sleep, the app attempts to reconnect for up to 15 seconds after it wakes up. Telescope position queries are now re-tried if they fail, for added reliability.
8. The problematic Keep Alive option in the Scope Communication Settings view has been removed, and is now permanently OFF. It has been replaced with an option to send the current time & location to the telescope when connecting; previously, this always happened by default.
9. A problem with setting the date and time on older Meade LX-200 telescopes, which prevented the app from connecting to them, has now been fixed. When connecting to Takahashi telescopes, the app now asks which side of the meridian the mount is on, if the scope has not yet been aligned.
