iOptron GEM45-EC Mount GoTo LiteRoc

iOptron GEM45-EC Mount GoTo LiteRoc: German precision mount with RA encoder

The iOptron GEM45 is a German equatorial GoTo mount with a payload capacity of 20 kg (45 lbs), excluding counterweight, at a head weight of less than 8 kg. The CNC-machined head combines the trusted GEM construction with the weight-saving technology from the CEM series.

The EC model measures the right ascension axis with a high-resolution encoder and corrects periodic error in real-time. With short and medium focal lengths, you can photograph without autoguiding.

The transport case is included in this set, so the precision head travels safely.

Real-time error correction on the RA axis

The encoder continuously corrects without PEC training or a guiding camera: sharp stars in long unattended exposures.

For long focal lengths, classic autoguiding via the ST-4 port remains possible.

GoTo, GPS, and heated handgrips

The Go2Nova 8407 hand controller contains over 200,000 objects and has a display heater for cold nights. The built-in GPS automatically sets the time and position.

Operation from the computer runs via USB; wireless operation with SkySafari or ASCOM is possible with the optional iStarFi WiFi module. Autoguiding via the ST-4 port.

Light, stiff, and tidy

Silent stepper motors, a periodic error under plus or minus 7 arcseconds with PPEC, and internal cable management that prevents snagging during rotation.

The 6-inch saddle accommodates Vixen and Losmandy rails; the large locking levers also work with gloves.
