German "precision go to" equatorial mount, compact size, exclusive 10Micron HPS technology with absolute encoders and high performance motor drives; payload 25 Kg (55 lbs).
10 Micron brings high level Italian craftsmanship to the world of astronomy with their GM1000 HPS Equatorial Mount. This splendid Go-To mount provides top notch quality all around, and is sure to easily prove its worth once you integrate it into your newest imaging system setup. Behold- the step of evolution that comes past perfection for German Equatorial mounts in the shape of 10 Micron's GM 1000. Built for the most demanding astronomers, the GM 1000 refines the design principles of German Equatorial mounts to provide the utmost possible quality for your usage.
The movements of the mount are driven by two servo-brushless motors, with timing belt reduction for zero backlash. Both axes utilize worm-wheel and worm gear driven systems in conjunction with the included absolute encoders to provide smooth, stable movement of the mount head when tracking or slewing. The worm wheels are constructed from Bronze, have 250 teeth, and are of a 125 mm diameter. The worms with which they link are constructed from an alloyed steel, ground and lapped, and rendered 20mm in diameter. The Axes themselves are crafted from a 30mm diameter steel alloy for maximum rigidity and stability. The double dovetail mounting plate guarantees the maximum compatibility with a broad array of telescope manufacturers.
Another part of this mounts most excellent composition is the control box in which the majority of the systems electronics are stored. This independent control box is easily removable, convenient for portability. The connections between the motors, encoders, and hand-pad all feature security lock screws for your safety and peace of mind. This mount can be controlled through the included extrnal keypad without any need for a PC to be connected to the mount itself. That keypad was built to maintain the maximum possible readability in a wide variety of light conditions, and to provide a convenient, portable interface for the scopes electronic Go-To system.
