Industry Leading Wireless Telescope Control System
SkyFi 3, our patent-pending WiFi-to-Serial adapter, is the only WiFi device on the market specifically designed for telescope control.
SkyFi 3 is battery-powered for field use; your scope, SkyFi, and phone all run off batteries, or from a 12V source. It has a battery life of 8 - 12 hours under continuous use.
SkyFi 3 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 3 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 3 is very compact, barely larger than an phone. It can be easily attached to your telescope's mount or tripod; a velcro loop is included for that purpose.
SkySafari Plus and Pro apps, for iOS, Android and macOS, are specifically designed to communicate with SkyFi 3 and your telescope over a wireless TCP/IP connection.

SkyFi 3® is our patent-pending WiFi-to-Serial adapter, designed for wireless telescope control. If you have a computer-controlled GoTo telescope, SkyFi 3 can use the WiFi capabilities built into your Android devices to point your telescope in the sky.
SkyBT® is our Plug & Play solution for wireless bluetooth telescope control for use with SkySafari on Android devices! Smaller than a business card, it easily attaches to RS232 serial ports via a DB9 male connector. SkyBT® is intended for Android only.
