Product Description

The industry-standard Losmandy G-11 is a rock solid visual and photographic tracking equatorial mount that can hold an instrument payload of up to 60 pounds. While not the most portable mount in the world, weighing in at 102 pounds with its 21 lb counterweight, it can generally be taken down and set up rather easily by one person, as the heaviest single component (the folding tripod) weighs only 45 lbs. This mount has excellent drive smoothness and accuracy, plus programmable periodic error correction, and is well-suited for astrophotography.

The inclusion of the new Losmandy Gemini II go-to hand-held high torque servo-based computer system turns the G11 into a full go-to computerized mount. The factory-installed Gemini II system includes an upgrade of the drive motors to higher torque versions that can support the high speed slewing of the go-to system.

The Losmandy Gemini II allows both stand-alone and PC-based control of the G-11 mount. The control electronics have the typical Losmandy hallmarks of being fully machined, anodized and brushed, with beautifully radiused edges that look like part of a Losmandy system, rather than a third party bolt-on. The new full-color graphic touch screen on the hand control clearly displays all functions. It has the classic four-button Gemini pattern for guiding, centering, moving, and slewing on both the touch screen and on a tactile four-button membrane on the rear of the hand control.

The new Gemini II feature set is comprehensive, making the system ideal for both casual observing and serious research. The system has been thoroughly tested in both Northern and Southern Hemispheres, and has been designed for precise and dependable use.

The heavy duty folding tripod allows the tripod head and legs to be stored and carried as a single unit, rather than the tripod head and three separate legs of the standard G-11 tripod, which must be assembled each time the mount is set up. This folding tripod version of the G-11 makes regular transport of the mount to a dark sky site and set-up easier than the standard non-folding tripod version, which may be more suited to a permanent observatory location.

DC Servo Motor Details

  • The upgraded DC servo motors on this go-to mount have higher torque through their entire range of tracking and slewing speeds than the standard G11 mount. The drive system has a dual 12~18V DC input/output and draws 3.0A maximum.
  • A full-color graphic touch screen on the hand control of the stand-alone Gemini II system clearly displays all functions. There is a classic four-button diamond pattern for guiding, centering, moving, and slewing on both the touch screen and on a tactile four-button membrane on the rear. There is also support for the original Gemini four-button controller.
  • The Gemini II has 0.5 arc second positioning accuracy during go-to operation. It is GPS-compatible with an optional receiver. It has Ethernet 10/100 with full IP function to permit operation from anywhere using a browser, ASCOM, or an application over the web or serial port.
  • The more than 40,000 object memory of the Gemini II is non-volatile and the system contains a real-time clock. You can select from English, French, and German language displays. There are two USB ports; one for virtual COM to PC, and one for an ASCOM or planetarium program. There is PEC correction built in and an auto-guider port. The firmware can be upgraded via the internet.

The G11 is the best High-End mount. The Gemini II has a modern touch screen that makes gotos easy. The new tucked motors and new spring loaded worm makes using the G11 so much easier to use than most other mounts. The spring loaded worm has very little if any backlash and you can set the balance even instead of having to worry about setting it East or West heavy like on other mounts. It's also has very low PE/periodic error making it easier when doing Astrophotography. The tripod is Machined aluminum that's anodized black and very solid. The mount head is also machined Aluminum that's anodized black and it looks great. And Losmandy has great service too. I am very happy with my Losmandy G11 with Gemini II and folding tripod.

Lightyears beyond my first equatorial mount (Super Polaris with SkySensor). All aluminum and SS construction, not a piece of plastic to be found. The Gemini 2 is a great system, straight forward and easy to use. You will not be disappointed! (Posted on 11/18/2018)

I just love this mount! It is easy to setup and align. It holds tracking very well, even when loaded with all my photography equipment. It connects easily to ASCOM software and there is all kinds of choices of software to go with it. Just a pleasure to use this mount. (Posted on 10/7/2018)
