Losmandy GM-8G Equatorial GoTo Mount with Tripod

Losmandy s GM-8G Equatorial GoTo Mount is an upgrade from the basic version of this mount with the addition of dual-axis high-torque DC servo motors and the Gemini 2 computer-controlled GoTo system. All hardware is made of stainless steel to 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. DC servo motors are reversible for use in the Northern and Southern Hemispheres and are powered by the included 12 VDC car/vehicle power adapter. Supporting the head and optical tube assembly (OTA) is an aluminum tripod with an adjustable height to accommodate a wide variety of users.

The brain of the GM8 mount is Losmandy s Gemini 2 computer hand controller. Equipped with a 40,000+ object database and updatable 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 (PEC) and declination-axis backlash correction to provide accurate, precise, and smooth tracking over long periods of time. Multiple guide, slew, and tracking rates allow it to be easily aligned and manually controlled and to accurately track near- and deep-sky objects. A non-volatile memory and real-time clock preserve settings, including backlash correction and PEC, when the system is turned off and power is disconnected.
