The new  GM 2000 HPS II COMBI mount from 10Micron combines the stability of the company’s GM2000 HPS II Monolith mount with the portability of the company’s GM 2000 HPS II Ultraport mount. These two mounts are no longer being produced and will be replaced by the GM 2000 HPS II COMBI successor model.

GM2000 HPS II COMBI MOUNTThis mount is basically a GM2000 HPS II Ultraport (“splittable” in two parts) with an additional locking system next to the quick locking system, which is useful to carry and assemble the mount in the field. A further locking system was added for customers who have the mount permanently installed in an observatory. This will ensure long-term stability, comparable to a GM2000 HPS II Monolith.

You can easily revert the mount into a portable (“splittable”) version simply by removing the locking screws. This way the new GM2000 HPS II COMBI combines both advantages of the previous models in one single mount.

HPS stands for H igh P recision and S peed. The GM 2000 HPS achieves a satellite tracking and positioning speed of 20 degrees / sec. with an average positioning accuracy of <20 “and a tracking accuracy of approx. 1” / 15min (peak to peak).

The GM 2000 HPS II COMBI also has high-precision absolute encoders on both axes, which opens up completely new possibilities. The mount never loses its orientation, even if the axes are adjusted manually. Even after a power failure, no new alignment is necessary. In mobile operation, the mount is quick and easy to set up and arrange.

The technical specifications, sizes and weight of the new GM2000 HPS II COMBI are exactly the same as of the retired GM2000 HPS II Ultraport which include:
