The iOptron GEM45 German equatorial mount melds fresh, innovative features with a classic design. Its sleek CNC-machined body isn't just for show—it's a testament to both the form and function of this high-quality mount.
Drawing from the know-how gained while developing our CEM series, we've optimized the GEM45 to eliminate extra bulk, resulting in an impressive payload-to-weight ratio of 2.5. This means the mount, weighing in at just 17.5 pounds, can handle up to 45 pounds of gear while executing precise GOTO and tracking functions. Polar alignment is hassle-free with the built-in iPolar electronic polar scope, even if the North Star is hidden from view. And you won't have to worry about fumbling with gear clutches; the GEM45 comes with large quick-lock levers that are a breeze to use, even when you're wearing gloves.
Cable entanglement? Not a problem. The GEM45 has an internal cable management system that keeps things tidy. It also features a 6-inch dual dovetail saddle compatible with both Losmandy and Vixen plates. The mount employs dependable stepper motors that are energy-efficient. And it stands on our newly designed LiteRoc 1.75" tripod, offering enhanced stability without the extra weight. Out-of-the-box, you'll get a mount with GPS, a 212,000+ object library, and even optional Wi-Fi capabilities via the iStarFi adapter.
