Testar Australia inspects and tests demo instruments and guarantees its quality. This SkyWatcher AZ-EQ6 is in excellent cosmetic condition and works perfectly.

  • All photos reflect the real condition of the item and are not taken from catalogues. What you see is what you get.
  • Every second hand/demo item is guaranteed with a 12 months warranty against defects.

This demo mount has been tested in real conditions under the sky. We guided a real star using a 600mm telescope and a guiding camera obtaining a pixel scale of 1" in order to verify the quality of the mount and the tracking accuracy. The minimum guiding time is 30 minutes that is sufficient to highlight and collect the periodic error and average the RMS. Then, we compare the tracking accuracy with the data obtain from other mounts to verify if the performance is in the norm.

The Sky-Watcher AZ-EQ6 GT is designed for the professional astrophotographer who wants a solid and reliable mount with a payload of up to 20kg. It combines the advantages of the equatorial mount with the simplicity of the alt-azimuth system. In fact, the AZ-EQ6 is a hybrid mount usable in both these configurations. The equatorial mode is ideal for astrophotography while the alt-azimuth configuration is more practical for observation as polar alignment is not required. 

When the mount is configured in Alt-Azimuth mode, it can carry a second instrument by attaching the dual saddle (Vixen and Losmandy style) to the counterweight bar. The detachable saddle has two adjustment screws that allow to rotate the saddle and align the secondary telescope with the main one. When the mount is set in alt-azimuth mode, the optical tube has to be mounted on the right hand side when pointing forward. 

In equatorial mode the AZ-EQ6 shows all its potential in astrophotography. It has a build-in polar scope with southern hemisphere reference and the polar alignment is easy and precise due to the azimuth and elevation screws.
It is compatible with the Ascom drivers but also allows to guide with the ST4 protocol. The periodic error can be reduced through the PPEC (Permanent Periodic Error Correction). Differently to the HEQ5 and the NEQ6, the AZ-EQ6 uses one belt for the transmission between the stepper motor and the worm drive rather than two gears. This belt reduces the overall backlash, the noise and the long period periodic error. Both axes are equipped with the belt transmission system.

The SynScan computerised go-to system has a database with 42,900 objects to quickly locate and slew to target. It has 9 slewing speeds up to 800 times the sidereal speed (3.3°/sec).

The AZ-EQ6 is equipped with a SNAP port for controlling the camera shutter release. Working with the SynScan hand control’s “Camera Control” function, you can take batch exposures in up to 8 groups of “Exposure-time & Frames”.

The dual dovetail bar can accept both Losmandy and Vixen style bars and the two tightening knobs do not touch the dovetail bar directly, avoiding marks on your telescope.
