iOptron GEM45 Innovative ideas applied to a time tested design, the iOptron® GEM45 next generation German equatorial mounts. A sharp looking CNC body is the first indicator the GEM45 is a top quality mount in both form and function.Utilizing experiences gained during development of our CEM series, we were able to remove unnecessary bulk giving the GEM45 an incredible 2.5 payload to mount weight ratio. This compact 17.5lbs mount can precisely GOTO an object and track with up to 45lbs of gear onboard. With its integrated electronic polar scope (iPolarTM), polar alignment is a snap, even when the pole star is obscured. Large levers on the quick-lock drive engagement system make it easy to snap its drive gears into place even when wearing gloves. There is little chance of your cables getting snagged with the GEM45's internal advanced cable management system. A 6" dual dovetail saddle accommodates Losmandy and Vixen style dovetail plates. GEM45 mounts utilize reliable stepper motor drive systems with our low power consumption technology. Our new LiteRoc 1.75" tripod delivers rock solid stability in a lighter, more compact package. A 212,000+ object library with star identification, GPS, Wi-Fi (requires optional iStarFi adapter) are a few of the desirable features standard on a GEM45 mount.
