Testar Australia inspects and tests used/demo instruments and guarantees its quality. This SkyWatcher HEQ5 Pro is in good cosmetic with minor pain scuffs but 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 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 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 HEQ Pro Mount is a portable mount for visual observers and professional astrophotographers who want a solid and reliable solution with a payload of up to 14kg. 

With a mount head weight of 10kg this professional mount is ideal to be carried anywhere in search of dark skies and solar eclipses. The integrated bubble level and the adjustable tripod legs make the levelling easy. The azimuth and altitude axis can be adjusted for a precise polar alignment (polar scope included).

The HEQ5
 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 Vixen dovetail saddle can hold Vixen bars.
