An evolution milestone of high-end telescope systems with 1.75m aperture.
This complete solution represents a fully integrated alt-az observatory system. The AZ1750 1.75m is equipped with quartz optics from ASA. This guarantees diffraction-limited performance and best micro-roughness values even under the most perfect Earth-based astronomical seeing conditions. With fast focal ratio, the design results in less obstruction, higher contrast, and a more compact system. The size and cost of your dome infrastructure is reduced.
1750mm f2/f6 Ritchey-Chrétien Nasmyth Focus is equipped with absolute encoder secondary mirror focusing unit and configurable with up to 4 Nasmyth ports.
ASA Direct Drive Technology
No gears NO belts. Precise closed loop control.
In professional astronomy direct drive technology has been used for some years now. We developed our own direct drive controller and motor system. No gears or belts are needed, there is no transmission no periodic error or backlash.
On the picture on the right you can see a completely, in-house CAD- and CNC-manufactured rotor of a direct drive motor for a telescope.
Direct drive means
- Fast acceleration – necessary for satellite tracking
- very stable and stiff
- precise pointing and tracking
- longer life expectancies because there is no wear & tear (since no moving parts)
- low to no-sound operation
- low power consumption
Increased efficiency:
The power is not wasted in friction (from the belt, chain, etc., and especially, gearboxes).
Reduced noise:
Being a simpler device, a direct-drive mechanism has fewer parts which could vibrate, and the overall noise emission of the system is usually lower.
Longer lifetime:
Having fewer moving parts also means having fewer parts prone to failure
Drive stiffness:
Mechanical backlash, hysteresis and elasticity is removed by avoiding the use of gearboxes
High torque at low rpm:
All ASA mounts have high precision absolute encoders on all axes.
Technical Details
We believe that the most important part in producing optics is the testing. So ASA decided that we invest in the best test equipment available, remove any measuring error as good as possible and use real values in our specifications.

The remote package contains an IP Camera mounted inside the Dome to remotely view the Telescope and an Uninterruptible Power Supply (UPS). The IP Camera allows to always view the telescope orientation to give you situational awareness of the observatory status. The UPS allows the telescope to keep operating during shorter (<30sec) power interruptions and to safely park the telescope in the event of a longer power outage.
This package contains sensors for sky and ambient temperature, rain and humidity and wind speed plus all necessary mounting material.
This package guaranties operational safety of your observatory in case of unsuitable or hazardous weather conditions. It also provides the operator with a web interface to monitor and log weather events.
