Losmandy Gemini 2 GoTo System Retro-Fit Kit

  • Add computerized "Go-To" capability to your Losmandy GM-8, G-11, HGM200, or G9 equatorial mount with the Gemini 2 Retro-Fit Kit!
  • The Gemini 2 is a DC servo based GOTO computerized positioning system, and includes a touch screen hand controller that is a joy to use.
  • The Losmandy Gemini II Retro-Fit Kit includes the main control unit, hand controller, two servo motors, two control boxes, and all the required cables and mounting hardware.

The Losmandy Gemini 2 Go-To 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 Go-To System Retrofit Kit can be installed on the Losmandy, GM8, G11 and HGM200 & G9 Mounts. This system is incredibly precise and the choice of astro photographers world wide. 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. 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 HGM 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 40,000 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.

The CPU on the Gemini 2 System uses a mounted PC board as its base. This is a proven set up and is one of the most reliable in the field today. The main board has auto-guider and accessory ports, for full remote control (via the web) of the system from a computer from anywhere in the world. The Gemini 2 uses a Meade LX200 inspired command set. Clock and location information can be updated through a Losmandy GPS accessory that is sold separately.
