SkySafari 6 will (optionally) backup your data to our secure cloud storage, syncing it across all your iOS devices, and making it accessible on LiveSky.com.**
We’ve updated to use the UCAC5 star catalog with 29 million stars down to 15th magnitude. And with an in-app purchase you can get a total 109 million stars.*
The PGC catalog has 784,000 galaxies down to 18th magnitude. And with an in-app purchase you can get a total 3.4 million galaxies down to the 21st magnitude.*
We made it easier to record observations and now associate them with Sites and Observing Lists, and collect them into Sessions that span hours, or nights.
The completely new graph tool will give a quick visual representation of an object’s altitude above the horizon. Essential for planning your night’s observations.
Our new updated planner lets you create a list of targets for your observing session with filters like object types, time range, constellation, catalog and more.
Tilt-to-slew allows you to keep your eye in the eyepiece, and use your device's accelerometers to gently translate your hand movements into smooth scope motion.
With a free signup you can view & share your observing data from LiveSky.com.** Affordable premium memberships allow for web editing & data management.

*** Cosmos Collection is an in-app purchase for SkySafari 6 (basic only) that allows you to travel to other planets and stars, visualize the 3-D location of deepsky objects in our galaxy, listen to hours of audio guided tours of the heavens, and learn to pronounce hard to say objects (i.e. “Yoor-a- nus”, not “Your-anus” - right?)

Industry Leading Wireless Telescope Control System
SkyFi, our patent-pending WiFi-to-Serial adapter, is the only WiFi device on the market specifically designed for telescope control.
SkyFi is battery-powered for field use; your scope, SkyFi, and iPhone all run off batteries, or from a 12V source. It has a battery life of 8 - 12 hours under continuous use.
SkyFi requires no pairing, and no special drivers. It uses standard TCP/IP networking protocols and enables your telescope to be remotely controlled over the internet.
SkyFi can wirelessly enable almost any Go-To telescope with a standard USB or RS-232 serial interface. All you need is the rs232 cable supplied by the manufacturer.
SkyFi is very compact, barely larger than an iPhone. It can be easily attached to your telescope's mount or tripod; a strip of double-sided Velcro is included for that purpose.
SkySafari Plus and Pro apps, for iOS, Android and macOS, are specifically designed to communicate with SkyFi and your telescope over a wireless TCP/IP connection.

SkyFi® is our patent-pending WiFi-to-Serial adapter, designed for wireless telescope control. If you have a computer-controlled GoTo telescope, SkyFi can use the WiFi capabilities built into your Android device, Mac, PC, iPhone, iPad, or iPod Touch to point your telescope in the sky.
SkyWire® is the simplest way to turn your iOS device into a 21st-century telescope controller. This brand-new "Made for iOS" accessory adds an RS-232 port to your iPhone, iPad, or iPod Touch - and lets it connect directly to the serial port on your telescope.
