What's New in SkySafari 6

We're pushing the envelope to the edge of the universe!

Data Backup and Cloud Sync

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 Have The Best Stars

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.*

We Have The Best Galaxies

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.*

Observers First

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.

Graph It

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.

Plan It

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.

Say It

SkySafari 6 adds basic voice control for a wide range of operations. Say “Select Jupiter,” “Search for Titan,” “Center on Polaris” and SkySafari will do it for you.

Tilt It

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.

Share It

With a free signup you can view & share your observing data from LiveSky.com.** Affordable premium memberships allow for web editing & data management.


* Largest mobile database requires in-app purchase of UCAC5 & PGC database extensions - only available in SkySafari Pro.

** LiveSky viewing/exporting/sharing of user data is FREE. LiveSky web editing of user data requires affordable premium membership.

"If you have even the slightest interest in what you can see and learn in Earth's sky, this [SkySafari 5] is one of the very best iOS apps you'll ever use."

John Martellaro, The Mac Observer, December 16th, 2015

Telescope Control

Industry Leading Wireless Telescope Control System


Market Leading

SkyFi, our patent-pending WiFi-to-Serial adapter, is the only WiFi device on the market specifically designed for telescope control.

Battery Powered

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.

Easy Set Up

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.

Telescope Compatibility

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.

Compact Size

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 Integration

SkySafari Plus and Pro apps, for iOS, Android and Mac OSX, are specifically designed to communicate with SkyFi and your telescope over a wireless TCP/IP connection.

Wireless WiFi Telescope Control

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 Mac, PC, iPhone, iPad, or iPod Touch to point your telescope in the sky.

Wired Telescope Control

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.
