iOptron GEM45G Mount GoTo LiteRoc

iOptron GEM45G Mount GoTo LiteRoc: German equatorial mount with built-in autoguider

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 G-version has the iGuider autoguider built-in: its own optics and camera inside the mount itself, so no more separate guide scope on the tube. Your imaging setup stays lighter, sleeker, and better balanced.

Together with the built-in iPolar and the included transport case, this is the complete photo set in the GEM45 series.

Guiding without off-axis guider

The iGuider makes continuous corrections via guiding software such as PHD2. Fewer parts and cables mean less that can go wrong during a long night.

The ST-4 port remains available for those who still want to use external guiding.

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.
