Losmandy GM811 GEM GoTo Mount W/ CW and LW Tripod

The GM811 GEM GoTo Mount from Losmandy is an excellent heavy duty German Equatorial mount with full Go-To capacity and includes both a counterweight and a tripod. This stainless-steel mount is a whole new model based on the earlier Losmandy GM8, and boasts all around superior features to hold over its predecessor. The GM811 utilizes a hybridized saddle that can fit both D and V style dovetails, allowing it to accept a very wide array of telescopes for use in conjunction with the mount. The included Light Weight (LW) mount is an excellent choice for supporting the GM811.

For transport purposes the GM811 can be split into two pieces, the RA and DEC Axes each forming a single hefty component of the mount before coming back together to form the GM811. All components of the mount are a black anodized combination of aluminum and stainless steel in both axes, each component having been ideally crafted and machined for their intended purpose. The 1.25" diameter counterweight shaft can be removed but has been designed with a safety stop to ensure it does not fall out unless you are intentionally removing it.

The mount as a whole utilizes the advanced Gemini Go-To system for maximum operating efficiency and power. This advanced software hosts a full color touch screen that displays almost all functions as well as the traditional four button pattern that enables guiding ,centering moving and slewing. With a database of over 40,000 objects inbuilt to the Gemini program and high level control made possible, you will find that the Gemini performs admirably well as a stand alone system without any need for a computer. Even with that said, you'll find the Gemini system is remarkably easy to integrate with your computer via both USB ports and a fully functional Ethernet port with full IP function. The Gemini is also compatible with a variety of auto-guider systems and is fully usable anywhere in the world, northern or southern hemisphere.

Wonderful mid-tier mount

My previous experience with a Go-to mount was a Celestron CGEM, and with upgrading to the GM811G w/ LW Tripod I am loving the jump in quality. There were some issues out of the box, the collar adjacent to the dec motor was scraping and causing a rub as the dec slewed. I had to adjust the placement of the housing a bit and loosen the collar's grub screw to eliminate this. Pros: - In general my PHD2 guiding performance has been in the .8" - 1.5" total RMS range, dependent upon seeing conditions. - Gemini 2 is an excellent go-to system, the ethernet port makes it really handy to network in and control remotely via PC. - You can tell that this is a well-machined mount, very impressed with the quality workmanship. The sound of the gear mesh is much more smooth & refined than the rough, ratchety noise of my CGEM. - LW Tripod has performed well, though I was a bit confused if there was intended to be an accessory tray with bolt threads in the tripod's brace. I was also unclear if the brace was intended to lock somehow (after calling Losmandy I confirmed it is not). - Combined weight of the GM811 mount + LW Tripod is an awesome option for folks with back issues who will be lugging their mount around assembled. Cons: - Balancing RA precisely is a bit tough other than using the back & forth push down method. - I realize they're busy, but sometimes email support hasn't been very responsive, I ended up calling - $ difference w/ CEM60, high cost All in all, it's an excellent package.
