Testar Australia inspects and tests used instruments and guarantees its quality. This SkyWatcher AZ-EQ5 is in excellent cosmetic condition and works perfectly. The pier tripod comes with an upgraded ratcheting bolt system.

  • 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 used 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 25-30 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.

This model use an improved system to tighten the mount to the tripod (Supatool T handle)

The Sky-Watcher AZ-EQ5 Pro Go-To with pier tripod is designed for the astrophotographer who wants a portable and precise mount with a payload of up to 15kg. It combines the advantages of the equatorial mount with the simplicity of the alt-azimuth system. In fact, the AZ-EQ5 is a hybrid mount usable in both these configurations. 

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-EQ5 shows all its potential in astrophotography. The polar scope is optional but nowadays with software like SharpCap or accessories such as the PoleMaster it is possible to get a quick and very precise polar alignment.
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-EQ5 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-EQ5 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 of 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.
