- Fixed some new problems with Night Vision mode introduced by a recent Android update.
- Locations in Arizona, USA now never observe daylight savings time.
- In Plus and Pro, fixed failure to apply alignment offset to GoTo commands for ServoCAT telescopes.
Improvements and bug fixes in release 1.8.2
The latest release of SkySafari for Android is 1.8.2, released on 5 September 2013. The improvements and bug fixes in this release are common to all three versions of SkySafari (Basic, Plus, and Pro) unless otherwise noted:
- Avoids startup crash on some Android devices by change sscanf format specifier for parsing asteroid names.
- Prevents repeat showing of the same startup announcement caused by a bug introduced in Android 4.3 where an extra newline is appended to strings read from the Preferences system.
- All timers now stop when the app exits. Prevents two update timers from running when restarting the app.
- Fixed blank screen problem where the display wasn't getting drawn if a valid location wasn't obtained because location services were disabled.
- In Plus and Pro, enabled local alignment (Sync) for ServoCAT/SkyCommander telescopes.
Improvements and bug fixes in release 1.8.1
SkySafari Plus and Pro for Android version 1.8.1 was released on 30 July 2013. This release is Plus and Pro only; these items do not affect the basic version, which is still at 1.8.
- Fixed crash when connecting to many telescope types by bluetooth.
- For Celestron telescopes running NexStar firmware version 4.18 and higher, SkySafari now uses current-epoch RA/Dec coordinates internally, when communicating with the NexStar Hand controller. This should result in more accurate position readouts and GoTos. SkySafari still uses J2000 coordinates with NexStar hand controllers running firmware before 4.18.
- Added support for iOptron iEQ30, SmartEQ, and ZEQ25 mounts with 8407/8408 controllers.
Improvements and bug fixes in release 1.8
The latest release of SkySafari for Android is 1.8, released on 16 July 2013. The improvements and bug fixes in this release are common to all three versions of SkySafari (Basic, Plus, and Pro) unless otherwise noted:
- Big performance improvement by enabling hardware floating-point processing.
- In Plus and Pro, added 3D models, descriptions, and images of Cassini and Voyager spacecraft, the International Space Station, and Hubble Space Telescope.

- In Plus and Pro, added support for telescope axis encoders on SiTech controllers in Push-To mode.
- In Plus and Pro, added option in Scope Setup settings to save the communication log file to the SkySafari Plus/Pro directory on your SD card. You can transfer them to your computer and email them to Southern Stars for troubleshooting.
- In locales that use ',' as the decimal separator, the numeric keyboard does not enable the "," key. We let the user type a "." instead, but we change the period a comma before trying to parse it.
- Manifest now indicates that most of our hardware requirements (bluetooth, compass, etc) are optional.
Improvements and bug fixes in release 1.7.5
SkySafari for Android version 1.7.5 was released on 16 May 2013. The improvements and bug fixes in this release are common to all three versions of SkySafari (Basic, Plus, and Pro) unless otherwise noted:
- Switched from third-party (crystax) Native Development Kit for building C++ code to google's own NDK. Turned on compiler optimizations, resulting in general performance improvements throughout the app.

- Improved compass performance.
- Fixed bug where the star magnitude limits could get corrupted if you zoomed in or out while doing a live adjustment of the mag limits. SkySafari no longer allows pinch zoom in Live Adjust (this is what the iOS version does).
- Fixed bug preventing multiple comets with the same name (e.g. C/2011 L4 and C/2012 S3, both PANSTARRS) from appearing in the comets list under Search.
- Improved performance when drawing many faint solar system objects. Default solar system magnitude limit is now 20, as opposed to unlimited; settings files now restore unlimited (infinite) magnitudes correctly.
- Implemented better test to see if the app is running on a tablet, and format Object Info descriptions in landscape mode.
- Now displays orbit epoch for satellites and solar system objects in Object Info. In Plus and Pro, conjunction/opposition/eclipses in Object Info now show the first such event taking place any time in the next 2 years, and the math runs much faster now.
- Fixed bug where two or more automatic solar system data updates could happen simultaneously, which could result in missing objects in some categories. Discard partial solar system data updates; all files must now download successfully before SkySafari will accept the updated data.
- When connecting to local Wi-Fi networks that are not internet-connected (like SkyFi or Nexus), Google Play licensing check no longer fails.
- Fixed small error in position computation for some geosynchronous satellites.
- In Plus and Pro, fixed crash that could occur at the end of an Orbit animation, or when returning to Earth from Orbit mode.
- In Plus and Pro, fixed long-standing bug where the app will fail to start if quit with the scope control panel visible and in night vision mode.
- In Plus and Pro, fixed problem preventing some stars from being drawn when very far from interstellar space
- In Plus and Pro, added a Bluetooth Picker to the Bluetooth option in Telescope Setup, so if you have multiple serial bluetooth adapters paired with your Android, you can choose which one SkySafari will use for telescope communication.
- In Plus and Pro, fixed problems drawing orbits with eccentricity very close to (but not exactly) 1, like that of comet PANSTARRS.
- In Pro, super-hi-res Earth/Moon/Mars maps now appear when panning or zooming is finished; no more jerky performance while panning/zooming in progress.

Improvements and bug fixes in release 1.5
SkySafari for Android version 1.5 was released on 17 May 2012. The improvements and bug fixes in this release are common to all three versions of SkySafari (Basic, Plus, and Pro) unless otherwise noted:
- In SkySafari Plus and Pro, you can now orbit other objects in the solar system! Select an object, then tap the new Orbit button in the toolbar to fly into orbit around it. If you select the Sun or any other star, you will fly far above the Sun, where you can see the whole solar system. Once in orbit, swipe to move around. New buttons in the lower left and right corners let you fly toward or away from the planet. When you're ready to return to Earth, tap the Home icon at the bottom of the sky chart.
- A new Moon map is based on imagery from NASA's 2009 Lunar Reconnaissance Orbiter. SkySafari Pro includes a super-hi-res version, with 8x the resolution of any other SkySafari version. When viewing from Earth, the Moon is always shown as a disk with its correct phase. The Moon's dark side now shows faint earthshine, and appears sky-colored in daylight. The sky darkens when solar eclipses take place.
- In Plus and Pro, you can now see the surfaces of Venus, Earth, and Titan without atmospheres or clouds. Mars's moons Phobos and Deimos are now shaped realistically. Saturn's moon Hyperion tumbles chaotically. Venus - or any other planet - now always shows as a black dot when transiting the Sun. Planet surface grids are drawn more accurately.
- In SkySafari Plus and Pro, planet and moon surface features are now labelled. So are the landing sites of every spacecraft that humankind has ever sent to any other moon or planet.
- Object Info descriptions for the planets and constellations have been rewritten. Learn about the mythology of the planets, the transit of Venus, and total solar eclipses!
- In Plus and Pro, Object Info data now shows angular separation between the currently selected object and the Sun, the previously-selected object, and the chart center. Object Info also shows opposition, conjunction, eclipse, and transit dates for solar system objects, as well as their apparent motion rates in the sky. Physical ephemeris data are shown for planets and moons.
- Asteroid, comet, and satellite orbits have been updated with the latest 2012 data. Numerous other small solar system computation and graphics bugs are fixed. In Plus and Pro, you can now show orbits of asteroids, comets, and satellites if you select them.
- You can now search for objects by typing a number without any catalog prefix. Searching for "104" will now find Messier 104, NGC 104, star HR 104, and asteroid (104) Klymene. You can now retrieve up to 10,000 objects in a search.
- If you turned on the compass by tilting the phone up toward the sky, it now stays on until you lower it more than 30 degrees below the horizon. In Plus and Pro, when connected to a telescope, tilting the phone will never activate the compass. A three-finger vertical swipe now zooms the display in and out.
- In Plus and Pro, you can now use the chart center as the telescope alignment/GoTo target by tapping the target label in the scope control panel. This lets you enter and GoTo to the exact set of coordinates of the chart center, or align on a point like the zenith (+90 altitude).
- Improved app icon and splash screen. If you don't like the new icon, please email your own design as a 512x512-pixel PNG image to email@example.com - we'd love to see your suggestions!

Fixed small inaccuracy in sunrise/set and moonrise/set times in the Date & Time settings. Fixed crash in Plus and Pro versions due to having more than 64 observing lists and miscellaneous other crashes.
- Increased font size slightly on the chart and in the status bar. In night vision mode, object lists now show objects below the horizon as slightly darker red font.
- In Plus and Pro, added format settings for Ecliptic and Galactic coordinates. Implemented Ecliptic coordinates on Plus.
Improvements and bug fixes in release 1.2
The latest release of SkySafari for Android is 1.2, released on 3 April 2012. Here are the improvements and bug fixes in this release:
- SkySafari now downloads its additional data from Google Play instead of Amazon. Data download for the basic version is smaller due to the removal of extraneous faint stars; and now contains all 46,179 stars brigher than magnitude 8.
- Fixed many missing or incorrect star/deep sky catalog numbers in the database. Updated star distances from new 2007 Hipparcos reduction. Updated default asteroid and comet data with the latest 2012 orbits from Lowell Observatory, JPL, and the Minor Planet Center. In Plus and Pro, added the brightest quasar (3C 273) and the brightest globular cluster in the Andromeda Galaxy (Mayall II).
- All three versions of SkySafari now show satellites! For example, you can now see the International Space Station by searching for "ISS". Object Info for any satellite shows when it will pass overhead; Plus and Pro show visible and non-visible (e.g. daytime) passes. The basic version of SkySafari automatically downloads new satellite, asteroid, and comet orbit data every week. In Plus and Pro, make sure to update your orbit data at least weekly to generate accurate predictions.
- All lists in the Search panel remember their scroll locations. User interface bug fixes: short swipes no longer select an object as well as moving the chart. Multiple copies of the app no longer get started when importing settings files and observing lists from email. Extraneous duplicate copies of user-defined locations eliminated. Hardware buttons no longer illuminated in night vision mode when leaving the main chart.
- SkySafari Plus and Pro can now auto-detect SkyFi's IP address from a user-defined name (requires SkyFi firmware 2.3 or later).
- In Plus and Pro, fixed problems connecting to Celestron NexStar controllers running firmware version 3, and to SiTech controllers on Alt-Az mounts. Implemented "Local Sync" function for iOptron controllers.
- Added support for periodic announcements from our web server. SkySafari checks for these when it starts up, and only shows them once.
Improvements and bug fixes in release 1.1.2
SkySafari for Android version 1.1.2 was released on 8 March 2012. Here are the improvements and bug fixes in this release:
- The chart now has "momentum" when you swipe it. The chart now performs animated panning to the selected object when you center it (instead of jumping there). This smoother and cooler experience can be disabled in the Appearance settings.
- When you select an object, SkySafari now shows its brief description in the status bar. You can show this again, later, by tapping the middle of the status bar.
- The backlit hardware buttons are now totally turned off when SkySafari is in night vision mode. Previously they were reduced to 25% intensity.
- Added request to "Rate SkySafari" on Google Play after the app has been run five times.
- In Plus and Pro, implemented Popup control panels to let you quickly change the coordinates and field of view. Access these panels by tapping the coordinates and field of view displayed in the upper left and right corners of the chart.
- In Plus and Pro, you can now select whether you want to use Bluetooth or Wi-Fi to connect to a telescope.
- In Plus and Pro, in the Telescope Display settings, added missing option to show cardinal directions on the telescope field of view indicator.
- In Plus and Pro, when connecting to a telescope, the app automatically switches to using current time, and ignores the "Tilt to Use Compass" feature. Fixed bug where the telescope's position was not being updated to correctly account for sidereal rotation of the sky.
- In Plus and Pro, prevents crash caused by leaving the Solar System Settings while a minor body orbit update is in progress.
- SkySafari now asks if you want to use or delete a user-defined location when you select one.

- Enabled use of custom horizon panoramas, and remove ability to set horizon altitude from the basic version.
- Fixed problem where screen wouldn't update after tapping the compass button when not using current time.
- Fixed the sorting order in searches. When searching for "Messier" the returned list was not sorted correctly.
- Fixed crash when tapping on an image link in the Object Info.
- In Plus and Pro, fixed crash when trying to import an "old style" observing list created on iOS. SkySafari now displays a message saying the list couldn't be imported, and creates an empty list instead.
Improvements and bug fixes in release 1.1
SkySafari for Android 1.1 was released on 11 February 2012. Here are the improvements and bug fixes in this release:
- Panning using the compass is now much faster and smoother.
- All screens now have an "x" in the top right corner so you can dismiss them and quickly return to the main sky chart activity (instead of having to hit the "back" button several times in a row.
- You can now import and display your own custom horizon panoramas by dragging them onto your SD card! You can also now turn the horizon glow on or off. In Plus and Pro, a new "Horizon Altitude" setting lets you show when objects rise/set above a specific altitude.You can add and delete Settings Files from your SD card.
- Multiple constellation display options can now be turned on at the same time. For example, you can now display traditional constellation lines overlaid with mythical figure images, or modern constellation lines and boundaries at the same time.
- A new searchable location database now includes every city worldwide with more than 100,000 people - 4092 cities in all. In Plus and Pro, the new searchable location database now includes every city worldwide with more than 10,000 people, plus more than 500 "astronomical" locations - a total of 30,470 in all (vs. < 1500 previously).
- You can now search for all objects in a star or deep sky catalog by typing just the catalog name or its standard abbreviation. For example, you can find all the Caldwell objects by searching for just "Caldwell" (or "C") without a specific object number. In Pro, Guide Star Catalog stars are now searchable by GSC number (like "GSC 8988-2501").
- Constellations are now searchable by common name (like "Southern Cross"). Searches for variable stars are now no longer case-sensitive.
- Fixed positions and magnitudes of certain nebulae. Secondary components of double stars are no longer labelled until you're zoomed in enough to see them.
- When zoomed in a very small field of view using local horizon coordinates, the chart should now follow the diurnal rotation of the sky, so stars and planets no longer drift off the screen.
- In Plus and Pro, optimized grid drawing. Grid lines become progressively finer as you zoom in, with no slowdown at all.
- In Plus and Pro, you can now set a custom time step with time flow animation, like 10 minutes, 7 days, 80164 seconds (one sidereal day), or 24.659784 hours (one Martian day).
- In Plus and Pro, If you were scrolling through on observing list when you last exited Search, SkySafari brings you back to exactly the same object in your observing list when you return to Search.
- In Plus and Pro, search results lists and other object lists can now be made into observing lists. You can add and delete observing lists and settings files by dragging them onto your SD card.
- In Plus and Pro, satellite visual magnitudes are now computed correctly, using Mike McCant's data whenever possible. Fixed slowdown caused by computing satellite positions with very out-of-date orbits. Dramatically faster planet/moon ephemeris computation for years before 2000/after 2020.
- In Plus and Pro, the telescope field of view indicator bullseye can now show cardinal direction (N/E/S/W) markers. The motion rate slider in the telescope control panel is now "hooked up" and works correctly.
- In Plus and Pro, added support for iOptron SmartStar, MiniTower, iEQ45, and Meade LS/LT mounts via SkyFi-USB. Added communication with Software Bisque Paramount via TheSkyX Server. Added ability to park SiTech mounts when disconnecting. Added separate telescope types for Orion SkyQuest XTg and Vixen Sphinx mounts.

- Fixed bug where app would crash due to stack corruption when tapping on a star inside an open cluster or in a crowded star field.
- Added Retry option in dialog that is displayed if license verification fails.
- Make sure the SD card's files directory is created create when the app first starts up. If a manually placed data zip file is found, we check its size against why we expect. Before downloading or installing the extra data files we now check if there is enough free space on the SD card.
- Fixed compass problems on Android 2.2. Better handling of compass near North. When turning on compass from Equatorial mode, horizon texture is now displayed correctly.
- Keyboard for Search interface now has a "Find" button.
- Separator lines in time flow and on top of tool bar are now colorized correctly. Improved appearance of main Settings screen. When returning to main sky chart from another screen (like Settings or Object Info), time flow animation re-starts correctly.
- Removed solar system limiting magnitude slider (not needed in the Basic version). In the Plus and Pro versions, fixed bug where Solar System magnitude limit wasn't getting set correctly via the slider.
- Plus and Pro versions now correctly read double star designations in observing list (.skylist) files.
- Plus and Pro have reordered scope types list to match iOS version. Added scope types for Vixen Sphinx and Orion SkyQuest XTg to make sure these are stored correctly in saved settings.
Improvements and bug fixes in release 1.0
SkySafari for Android 1.0 was released on 21 December 2011. Here are the improvements and bug fixes in this release:
- Added Android Market licensing code.
- Made improvements to code which imports settings files and observing lists in SkySafari Plus and Pro.
- Implemented ability to save user-defined locations.
- Temporarily disables telescope communcation while panning/zooming the sky chart, for smoother performance.
- Added time to date/time display in status bar.
- Fixed crash in displaying Object Info after installing downloaded data. Miscellanoues fixes in C code to improve overall stability.
- When launching for the first ime in landscape mode, sets default chart center altitude to 15 degrees to make horizon visible. Star nagnitude limits are now the same as on the iPhone/iPad versions.
- Added one-time startup tip about swiping toolbar to access additional icons.
- Chart center coordinates displayed at the top of the main sky chart should now be updated when you center the chart on an object, and when the chart is locked on a moving object.
- Miscellanous user interface tweaks.
Known Issues and Remaining Work
- Sky & Telescope's SkyWeek functionality is not yet integrated into the Android version of SkySafari (as it is for the iOS version.) We're still working on it. In the meantime, you can download the free standalone SkyWeek app from Sky & Telescope's account on the Android Market!
- In night vision mode, the on-screen keyboard does not appear with any "red filter" over it. We suggest you download Alex Pruss's free Gingerbread keyboard with Night Vision from the Android Market.
- We've done no work to support video out. If your Android phone supports video-out hardware mirroring, then this may automatically work for you, but no guarantees.
- Ditto for Push notifications.
