  2. 10Micron: German "go to" equatorial mount, professional grade, exclusive 10Micron HPS technology with absolute encoders and high performances motor drives; high payload capacity of 100 Kg (220 lbs).

    Evolving perfection.

    The GM3000 HPS mount is built for observatories with an instrumentation up to a weight of 100 kg – 220 lbs (excluding counterweights). It is ideal for remotized observation sites, and its loading capacity allows for mounting instruments like 200 mm diameter refractors, 300 mm diameter Newton reflectors, 450 mm diameter Cassegrains and so on. Movements are driven by two  servo brushless motors, with timing belt reduction having zerobacklash. Both axes feature a classic worm – wormwheel pairing. The wormwheels are made of bronze (B14), with a diameter of 244 mm and 315 teeth in right ascension, and a diameter of 192 mm and 250 teeth in declination. The worms are made of alloy tempered steel with a diameter of 32 mm and 24 mm respectively. The axes themselves are made of alloy steel, with a diameter of 80 mm (right ascension) and 60 mm (declination), for the maximum rigidity.

    The electronics is housed in an independent control box, easily removable. The connections of the mount and keypad secutiry lock screws. Only one cable runs from the control box to the mount. The axes feature an hole allowing for the passage of instrumentation cables. This effectively solves the problem of entangling cables and damaging instruments, especially for remote observatories. The mount is powered with low voltage, requiring a maximum power of about 100W. This makes possible using the mount even in locations with limited power available. The GM3000HPS can be controlled completely using the included keypad, without requiring any external PC.

    The keypad is built in order to maintain the maximum readability in all lighting conditions. Both the display and the ergonomic keys, allowing for the use of gloves, feature a red backlight. An heater keeps the display warm for usage below freezing temperatures. The mount can be controlled using the most common software packages by connecting it to a PC with the RS-232 serial port or the Ethernet connection, via the 10micron ASCOM driver or the Meade compatible command protocol. Furthermore, a dedicated software (also included with the mount) can be used to create a “virtual keypad” replicating exactly the functions of the physical keypad. The RS-232 port can also be used to control an external dome. This flexibility makes the GM3000HPS an ideal mount for observatories and remotized observing sites. The object database contains many star catalogs and deep-sky objects up to the 16th magnitude. Solar system objects can be tracked so that their motion is compensated with respect to the stars. You may load orbital elements of comets, asteroids and artificial satellites into the mount, so that these objects can be tracked directly.

    Pointing is made accurate through the usage of a model containing up to 100 stars, which allows for the correction of the classical polar alignment and conic errors, and also of the most important flexure terms of the optical tube. In this way it is possible to obtain pointing accuracies of the order of 15 arcseconds RMS. The same model can be used in order to obtain the maximum tracking accuracy, compensating also for the atmospheric refraction (depending on the local atmospheric pressure and temperature).

    A series of auxiliary functions is provided to help the user for quick aligning the mount to the celestial pole. You may also save and recover the alignment data of different observing sessions. This function is very useful if you have many instruments in different setups, each one requiring different flexure corrections. Tracking through the meridian, a typical problem with german mounts, is solved allowing for tracking for up to 30° past the meridian (configurable), in both directions. In this way any object can be tracked for at least four hours.

    The tracking accuracy makes autoguiding not necessary for many uses.


    The absolute encoders on both axes allows to obtain a typical tracking error below 1 arcsecond. It is possible to autoguide anyway, using the ST4-compatible port or through the serial/Ethernet connection, with a guide rate configurable from 0.1x to 1x. The guide rate can be automatically corrected for the declination of the target, so that there is no need of recalibrating the autoguide when observing at different declinations. The mount has also dedicated function for easy use in the observatory. A dedicated connector on the control box panel is used for remotized switching on and off. The instrument can be electronically balanced, without disengaging the worm from the wormwheel. The mount can be parked in different user-defined positions. The serial RS-232 port can be used to control directly an external dome, avoiding the need of using a dedicated external PC. Once configured with your instrument parameters, the firmware is able to make all the calculations required for positioning the dome slit in front of your optical tube, for almost all instrument configurations.

  3. 10Micron: Flange adapter to accommodate different clamping plates (3” and 4”) on the GM3000 mount

    This flange adapter allows the use of 3 different dovetail clamping plates on the GM3000 mount:

    10M-2135 – Maxi 4” Clamping Plate
    10M-2085 – 3” Losmandy Clamping Plate
    10M-2185 – 3” Losmandy Clamping Plate XL

    Note: Although it should be possible to accommodate the plates directly on the top of the GM3000 mount, due to the low profile of the clamping plates we strongly recommend to use this Flange Adapter in order to operate the plate’s knobs with enough clearance.

  5. 10Micron: This kit is composed by a Shipping wooden pallet-box (#10M-3100) and a Pier adapter (#10M-3090); it’s mandatory for all the GM3000 orders to be shipped

    GM 3000 mandatory shipping KIT is composed of GM 3000 shipping wooden pallet-box (#10M-3100) and Pier adapter (#10M-3090), both are necessary items when the mount will be shipped by a forwarder. Shipping charges will be calculated individually for each destination and will be billed separately. The included Pier adapter #10M-3090 will be needed later when mounting the GM 3000 onto a 10Micron pier, a Baader pier or a custom made pier. This strong plate of solid steel is mandatory not only to secure the mount on the pallet during transport but also later to translate the full loading capacity of the Mount onto the pillar-
