This mount is based on the mechanics of the GM4000 HPS II and offers a very stable altazimuthal configuration: the AZ4000 HPS is a very versatile research mount, perfect for scientific activities such as satellite tracking, photometric and astrometric measurements, LiDaR laser applications and so on. Due to its altazimuthal design, this special mount isn’t suitable for astrophotography and for most of the amateur activities.
The standard version allows to assembly the optics to only a side of the mount and is supplied with a counterweight bar.

As option, is available the double telescope version which allows the use of two two or more optics in a side by side setup, optimizing the load of the Mount and taking advantage of the altazimuth configuration.

The Double telescope option i s compatible with all the plates used on the GM4000 series, including the dual plates Loduel and Maxidual; in this way is possible to use directly 4 optics, 2 per side.

Designed to offer a great sturdiness with no flexures, is all made from machined aluminized alloy. You can order the AZ4000 HPS Mount already configured with the Double Telescope option, or buy it after as an accessory.

The AZ4000 Mount is available in a special version for very low temperature operations.

This option allows the Mount to operate until -35°C (-31 F) and features the following special modifications:

  • Special low temperature lubricants certified until -60°C or lower
  • Special copper wiring, silicone sheathed
  • Electronic components certified for temperature until -40°C
  • Endurance test at -35°C in our laboratory

Our mounts feature special systems in their mechanics in order to compensate thermal variations.
This option is intended for brand new mounts to be ordered; contact us for already delivered mounts

10M400DAZ – This option allows a double telescope configuration as shown on the pictures above

The Standard version allows a single telescope assembly and  is supplied with a counterweight bar.
