The Losmandy Gemini GoTo System is a servo motor based computerized positioning system for the Losmandy Mounts. Losmandy has updated the Gemini GoTo System to include a newly enhanced CPU and increased memory. Perhaps most impressive is the interactive color touch screen that comes with the Losmandy Gemini 2 Go-To System.

The Gemini 2 GoTo System is incredibly precise and the choice of astrophotographers worldwide. Precise object tracking is achieved as a result of the servo motor system Losmandy utilizes. The servo motor system runs with a continuous and smooth rotation, for better tracking. A spring-loaded worm has been added to the RA and DEC axis. Further, the Losmandy system has an elevated level of torque which allows it to produce slewing rates of up to 8° per second with the GM-8 mount, 6° per second with the G-11 and 5° per second with the Titan Mount. The Losmandy Gemini system is a great instrument for use in the field because it can be run as a stand-alone system. With a 42,000+ object database and an illuminated Color LCD touch screen, this mount is a pleasure to use. Powering the unit is simple; all you need is a 3A, 12-18 Volt DC power supply.
