Product information

The GEM45 is the first of iOptron's next generation German equatorial mounts. 


Using experience gained during the development of their CEM series, iOptron have removed unnecessary weight resulting in a portable 7.2 kg / 15.8 lb mount with an impressive 2.8 payload-to-mount weight ratio. 
With its integrated electronic polar scope (iPolar) polar alignment is a breeze, even when the pole star is obscured.

IOptron's reliable ultra-quiet stepper motors provide precise pointing and tracking together with low power consumption. Large levers make it easy to engage the drive gears into place, even when wearing gloves. 

Integrated internal cable management means there is little chance of your cables becoming snagged and a new, patent pending, Universal Self-Centering Saddle (USCS) accommodates both Losmandy and Vixen style dovetail plates. 

A new 'LiteRoc' 1.75" tripod delivers high stability in a lighter, more compact package.

Other features include computerised GOTO with a 212,000+ object library (includes star identification) GPS and Wi-Fi (requires optional iStarFi adapter).
