The iOptron GEM45G is built for astrophotographers who want to combine precision, portability and convenience. This compact German equatorial mount delivers professional performance in a lightweight design - ideal for those who are often on the road with their telescope.
Powerful, light and precise
With a carrying capacity of 20 kg and an own weight of only 7.2 kg the GEM45G offers an impressive power-to-weight ratio. So you can easily take it with you to dark observing sites without compromising on stability.
The mount is designed to move smoothly and accurately. Thanks to the stepper motors and the worm gear mechanism follow your sky objects perfectly, even at long exposure times.
Smart design for easy use
The built-in iPolar electronic polar finder makes alignment child's play - even when the Pole Star is not visible. With the large clamping levers adjust the mount effortlessly, even with gloves on.
The internal cable management system keeps cables neatly inside the mount, so you don't suffer from tangle or breakage while shooting.
All-in-one with iGuider
The GEM45G has something unique: an integrated iGuider autoguider. That means you no longer need a separate guiding camera or setup. The system automatically corrects small tracking errors so that your photos stay sharp - even during long exposures.
Advanced technology at your fingertips
With the GoTo control and Go2Nova 8407 hand controller navigate effortlessly through a database of 212,000 sky objects. The built-in GPS automatically determines your location and time so you can start observing faster.
Want wireless control? Simply connect the optional iStarFi WiFi adapter on and use your smartphone or tablet for control.
Light but stable tripod
The LiteRoc tripod combines sturdiness with comfort. The legs of 45 mm steel give stability, while the clever design makes the whole thing lighter. This keeps your setup stable, even with heavy telescopes or cameras.
