Mount up to 130 lbs of Payload!
Astroimagers who specialize in advanced astrophotography will find several perks and strengths in the latest version of the 10 Micron GM2000HPS mount, the Version M2. This particular model is specifically tailored for amateur astronomers who intend to work with exceptionally large optical tubes weighing up to 130 lbs (excluding counterweights). These optical tubes have mighty light gathering power and depending on the camera resolution and sensor format size being used, can render fabulous detail and analysis of deep sky objects with the invincible tracking accuracy of the GM2000HPS II Combi with the absolute encoders!
Tracking Accuracy is Spot On!
Long exposure astrophotography typically entails more advanced tracking equipment due to even slight blunders and errors compounding in appearance into the final frame. Having razor sharp tracking and and a resilient design prevents this from happening since all frames are aligned making post processing relatively easy.
Using two AC servo motors to facilitate tracking and slewing, the mount uses a timing belt reduction reduction system to keep backlash at bay. The effects of backlash while initially can sound negligible, can have a major negative impact on final frames since even slight flexure and movement can misalign consecutive exposures. This is a crucial feature to have to remedy this issue.
There are bronze (B14) 172mm diameter 215 teeth wormwheel configurations placed on the DEC and RA axis with 24mm alloy steel worms installed within. The dual axes are machined from high quality alloy steel for superb strength and shelf life.
With a 100 star blueprint, the mechanics of the mount can remedy many errors caused by typical alignment methods up to 20 arcseconds of RMS.
A meridian flip is a typical scenario in many equatorial designs that requires a reslewing of the mount when an object crosses the meridian, thus its highest altitude at a given point in the sky when it is in clearest view free from atmospheric interference. In the case of the 10 Micron GM2000 HPS II, it can track up to 30° beyond meridian both ways, essentially removing a barrier to long exposure frames for objects near their highest point.
Mount Electronics and Control
The GM2000 HPS II electronic components are housed in a separate detachable box that is often locked to ensure safety.
Included with the mount is a 10 Micron hand control unit (10M5030) with a red illuminated backlight that can be operated safely in nighttime condition. There is also a heater to keep display warm.
The included RS-232 serial port or ethernet connection serves to facilitate control of the GM2000 HPS II using the ASCOM driver or the Meade compatible command protocol with a standard PC. The software also can serve as a virtual keypad, a digital replica of the physical included version. An external dome can also be controlled via the RS-232, further making the mount an ideal choice for amateurs in remote observing locations. The database inside the mount controller and software goes down to 16th magnitude, including many faint stars and deep sky objects in the NGC catalog and beyond.
Autoguiding only needed in rare circumstances!
Due to its renowned and cutting edge tracking, autoguiding is typically unnecessary, particularly credited to the absolute dual axis encoders which can track errrors of less than 1 arcsecond. There is still an included ST-4 port if the user chooses to autoguide otherwise with adjustable rates ranging from 0.1x to 1x. It can be automatically corrected based upon the declination, thus no need for recalibration when obsering different declinations throughout the celestial sphere.
