I have the GM2000HPS... Great mount - I'm about to write a review on it. The build quality is exceptional and I run it unguided for half and hour at FL around the meter mark.
Mine is the UP-version - Ultra Portable. Depending on your body build, that term may or may not have meaning
It splits into the base with Ra and Dec. I have the dedicated flight cases for them. The tripod, "Centaur", is really sturdy but very heavy. I would think it is steadier than a pier, actually.
The only down-side has been the ASCOM support. It relies on the LX200 or AP ASCOM drivers available previously and they simply do not work well. The solution for was to write my own ASCOM driver, which I gave to Baader Planetarium. 10Micron has a beta out for an ASCOM driver, but having written a good one myself I haven't bothered with it. Mine supports everything including pulse guiding, on-the-fly conversion between JNow( which the mount uses) and J2000 (which CCD Autopilot wants to use) and syncs that can be chosen as single point model adjusters or sync model refine points.
In contrast to other modern mounts, the 10Micron HPS series keeps the pointing and tracking model in-mount. This means that you get perfect two-axis tracking even when your controlling software bites the bullit and goes south.
The hand control sports the best functionality I have ever seen. Easy to use and full of good features. This mount you can definitely use without a computer.
Now, building a model (and the mount supports 25 points) can be a tideus task. I solved that by writing a model builder that I may release as donorware. Having Pinpoint and MaximDL as backend, this software builds a complete model from scratch in about 10 to 15 minutes with no user intervention.
As for robotic use, well, there is nothing like it! Having absolute encoders you can do what you want with it, power on or power off, and it will always know where it is.
In summary, a great mount and I love it! In fact, I am re-locating it to a remote site and getting a GM1000HPS as well to take its place on my balcony pier!
Stay tuned for a proper review.
All the best,
p.s. If a 10Micron mount user wants the ASCOM driver - let me know.
