Losmandy's G11 GFT Motorized EQ Mount with Gemini 2 GoTo System provides users with a powerful platform built to support and move larger optical tube assemblies. With a total payload capacity of 100 pounds, the head will comfortably carry 40 pounds of counterweights leaving a hefty 60-pound capacity for OTAs and accessories. All hardware is made of stainless steel to handle the weight as well as resist wear over years of use, while a dual dovetail saddle will accept the common Vixen-style plates and the larger Losmandy D-style plates. A dual axis DC servo motor is reversible for use in the Northern and Southern hemispheres and is powered by the included 12-18 VDC car/vehicle power adapter. Supporting the head and OTA is an aluminum tripod with an adjustable height to accommodate a wide variety of users.

The brains of the G11 GFT system is Losmandy's Gemini 2 computer hand controller. Equipped with a 40,000+ object database and updateable via the Internet, it sports a full-color display, an intuitive user interface, and an Ethernet 10/100 port for remote PC control. It features Periodic Error Correction and Declination-axis backlash correction to provide accurate, precise, and smooth tracking over long periods of time. Multiple guide, slew, and tracking rates allows it to be easily aligned, manually controlled, and to accurately track near and deep-sky objects. A non-volatile memory and real-time clock preserves settings, including the backlash correction and PEC, when the system is turned off and power disconnected.
