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.
