About this product

Model:  iop_gem45ec_7603eca_1.75
Part Number:  7603ECA

Next generation design!  Includes a high resolution encoder on the RA axis for real-time periodic error correction.

The GEM45-EC 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. 

An integrated electronic polar scope (iPolar) makes polar alignment a breeze, even when the pole star is obscured.

Ultra-quiet stepper motors and a high resolution encoder on the RA axis provide precise pointing and low periodic error (<0.25 arc seconds rms). 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).
