1100GTO German Equatorial Mount

Mach2GTO German Equatorial Mount


Mach2GTO Universal Robotic mount that sets a new standard for portable telescope mounts. It is so easy to use that you will be up and running in no time at all and the mount will simply disappear into the background. No fuss, no bother.

Universal Robotic means that Mach2 fulfills all of the requirements of a robotic mount for automated operation for imaging, satellite tracking, comet tracking, star survey work and others. In addition, the clutches allow it to be used manually for star sweeping. It is so easy to use that it can be set up quickly in the field with minimal effort and no complicated startup routines. The encoders keep track of the axis positions at all times whether parked, unparked, power on or power off.

AP will begin shipping new production run in July and throughout the summer and early Fall. Once you place your order, we will charge your card 50% of the total as a deposit and invoice you later for the remaining balance once your mount is ready to ship.

Price Range: $11,190 to $13,590


  • Polar Align, Power Up and Go!
  • Renishaw Absolute Encoder for the ultimate in precise tracking - no SDE or random errors above 1/4 arc sec
  • Absolute encoder provides near zero tracking error and resists outside influences such as wind and cable drag
  • Precision balancing via the clutches without taking the worm gears out of mesh
  • Brushless Micro-step Servo System for precise and whisper-quiet slewing and tracking

  • Custom tracking rates in both axes (for asteroids, comets, satellites)
  • Auto-Adjusting gear mesh
  • Image all night without meridian flip, as long as your scope clears
  • Daytime polar alignment is now simplified since we have encoders to set the positions
  • Precision azimuth adjuster with rotating base

  • Built-in bubble level & compass
  • Right-angle polar alignment scope (optional) 
  • Through-mount cabling (optional)
  • Modeling in Keypad & GTOCP5
  • Fully supported enhanced ASCOM driver 

  • Portable – under 40 lbs
  • Operate with 12V battery or up to 24V power supply
  • Ideal for 6-7” refractors, 8-12” SCTs and Maks
