Astro Physics Mach2 GTO
[AP Mach 2GTO]

Prijs: 10.650,00 EUR

Product Details

We are absolutely excited to introduce our new 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.
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
Dual-model pointing and tracking rate correction even with the telescope in the counterweight UP position. using Astro-Physics Command Center (APCC) Pro version, included
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
Fully supported enhanced ASCOM driver
Threaded for QHY Polemaster AP900 adapter (shown in photo)
Portable – 42 lbs
Operate with 12V battery or up to 24V power supply
Ideal for 6-7” refractors, 8-12” SCTs and Maks
GTOCP5 Control System
We have developed a new control system which combines the precision performance of the Renishaw Resolute Absolute Encoder with the whisper-quiet motion of brushless micro-step servo motors to produce a very accurate observatory-grade mount that can also be set up in just a few minutes in the field. The mount can be operated manually via the clutches or electronically with the encoder loop providing the pointing and tracking functions.
Use of Absolute Encoders means that the mount always knows where the axes are pointing and don't need to establish home on power-up.
The mount can be operated manually via the clutches or in full GoTo mode via keypad or external software.
Absolute Encoders are dead accurate in slewing, pointing, tracking, guiding. Periodic error and backlash, reversal delays in Dec are eliminated.
Rapid feed-forward servo loop stiffens the axes against outside disturbances such as cable drag and wind loading.
Both axes can be run at custom tracking rates from sub-arc second motions per hour to 1000x sidereal.
The GTOCP5 brushless servo system can be run from 12 volts to 24 volts with max slewing from 1200X (5 deg/sec) to 1800X (7.5 deg/sec).
The power to the motors is self-limiting and cannot cause any kind of damage to the windings or the electronics, even when in a stalled state.
GTO Keypad (optional purchase)
The Keypad is a self-contained computer that allows you to control all essential telescope functions and includes an extensive database of objects. Many people do not want to bother with a computer in the field and like the handiness of the Keypad and its ability to operate in very cold temperatures. The Keypad is an ideal choice for these users.
We have designed the interface and firmware to be as intuitive and easy to use as possible, while filling it with terrific features to make your observing session productive and pleasurable.
Optimized for Astronomy
Astro-Physics mounts and the Astro-Physics GTO Servo Control System are designed from the outset as tools for celestial observing and imaging.  These mounts do not have any military or defense applications. Applications like missile, airplane, or very low earth orbit satellite tracking require faster tracking rates and more rapid changes to those tracking rates than our mounts allow.   Note that the ISS is generally within the mount’s tracking rate capabilities.
