  • Portable
    Extremely solid, rugged, high payload mount, yet comes apart in two reasonably light-weight components for hassle-free field setup. No tools needed to assemble the mount in the field.
  • Operate with 12V battery.
    You can take it to the darkest skies and power it with a commonly available 12V battery. In the observatory, we suggest a minimum 5 amp filtered, regulated power supply.
  • External computer not needed.
    The keypad is a handheld computer with all of the features, functions and databases you need to tour the universe night after night. The unique software allows you to precisely polar align your mount in the field, even in broad daylight! The vacuum-fluorescent display with a temperature range of -40 degrees F (and C, they are the same in this instance), allows hardy observers to use this mount on cold winter nights. You can't do that with a PC!
  • Separate computer control.
    All functions of the servo drive can be commanded from a laptop or desktop computer using popular planetarium software. Depending on the features of the program, you can position your telescope, center your image and control tracking rate, remote focusing, reticle brightness and park at the end of your observing session
  • Servo Motor Drive
    The drive system uses a high-quality Swiss DC servo motor controlled by a microprocessor to an accuracy of 0.05 arc seconds per step. Tracking is very smooth, noticeably smoother than any stepper motor drive or inexpensive servo drive. The system can be accurately controlled over a speed range of 4800:1 which allows 0.25x sidereal for guiding to 1200x sidereal for 5 degree per second. The circuit draws only 0.4 amps when tracking the stars, 2 amps with both motors slewing and requires only 12 volts to operate. This servo drive will satisfy the requirements of the sophisticated, advanced astrophotographer, yet is easy for the casual, visual observer to use. Please refer to GTO Control Box and Keypad for Servo Drive for additional information.

A God-sent
I doubt one can find the words to do justice when describing this wonderful mount. Aside from being rock solid, it is engineered in such a way that you will begin to appreciate its design and layout each and every night.

The periodic error before correction is less than 5 peak-to-peak and well under 1 (peak-to-peak) when correction is enabled using either the AP version of PEMPro which comes with the mount (for free) or user/CCD corrections.

Once polar aligned, startup during each session involves a trivial one-star synchronization that takes a few seconds (point to a well-known star up in the sky and use the keypad to inform the mount which star it is).

For the astrophotographers, there is a wonderful option where one can delay (or advance) a meridian flip so that the imaging session will not be compromised (as an aside, the mount can easily track and allow one to image when our object has passed the meridian without the slightest problem). Of course, the mount will get the object (any object) of interest right on the chip each and every time so that the only user intervention will be to fine-tune the centering so that a suitable guide star is on the guide chip.

The keypad is a mini-planetarium and a mini-control center, thus allowing the use of the AP1200GTO without the need of a computer.

I sincerely doubt one will look for a better mount after having acquired the AP1200GTO. There is no better mount!

I sincerely doubt I will ever have the impetus to sell my AP1200GTO. I have grown so attached and appreciative to it that it has become my most faithful assistant and partner when imaging.

Excellent, rock solid performer
I have owned an AP 1200GTO for nearly a year now and have used it both for visual and CCD work.  The mount tracks incredibly well (PEMPro measures under 2 total PE) and is rock solid under the 85 lbs it is carrying.  I did uncover a small bug in the mounts software but AP responded quickly and corrected it quickly.  My mount is housed in my observatory and while scopes may come and go, I cant imagine parting with the AP 1200GTO.

Your last mount...
Barring the need for something that carries more than the 140lbs rated load, this is going to be the last mount you own.  This mounts tracking is unbelievably smooth.  Goto is dead-on every time.  The attention to detail in the design and build quality of these mounts is first class.  AP is famously supportive of their products.  If youre reading this review and are considering one of these mounts you must have seen many superlative statements like these by others, theyre true.  I wish I had two of these mounts...
