The evolution of mounts

The DDM100 ASA´s smallest telescope mount

ASA Direct Drive technology with absolute encoders for high end applications


New design based on 15 years of experience with Direct Drive systems.
Ready for the most demanding situations in pointing and tracking performance Load capacity of 100kg/220lbs on a polar wedge.

Characteristic features

To achieve the excellent tracking and pointing performance ASA Direct Drive systems are equipped with high resolution up to 28bit (0.004 arcsec) encoders on each axis.

After modelling the pointing with the ASA software package, the positioning error is usually better than 5 arcsec RMS, the tracking performance is in the range of +/- 0.25 arcsec up to 10min (only guaranteed with ASA telescopes).

The ASA DDM100 is the entry into all kinds of research work, including astronomical observation and satellite tracking.
