Testar Australia inspects and tests used/demo instruments and guarantees its quality. This SkyWatcher NEQ6 Pro is in good cosmetic condition and works perfectly. This specific mount has a particularly low periodic error of about 2.5" (!). You can analyse the guiding log using PHD2 log viewer.

  • 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 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 SkyWatcher NEQ6 Pro Go-To is a heavy duty mount with the highest payload for its price. For visual observations it can hold f/5 Newtonians up to 25cm in diameter or f/8 refractors up to 15cm. For astrophotography the NEQ6 represents an affordable option for large instruments such as Newtonians up to 20cm in diameter or refractors up to 12cm. 

It includes a polar scope with the southern hemisphere reference, an integrated bubble level and an adjustable tripod for a quick set up. 

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). 

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