ASA DDM200 Direct Drive EQ Mount 200kg Imaging Capacity

Price includes VAT, plus delivery



The DDM200 is the result of ASA’s 15 years of experience working with Direct Drive systems. It is the mount of choice for the most demanding pointing and tracking solutions with loads up to 200kg

To achieve the excellent tracking and pointing performance ASA are renowned for, ASA Direct Drive systems are equipped with encoders with up to 28bit (0.004 arcsec) high resolution encoders on each axis. After a pointing model is created using the ASA software package, the positioning error is typically better than 5 arcsec RMS, with tracking performance in the range of +/- 0.25 arcsec up to 10min (only guaranteed with ASA telescopes). The ASA DDM200 is the entry into all kinds of research work, including astronomical observation and satellite tracking. Astrophotography is usually conducted without external guiding thanks to ASA's proprietary MLPT (Multi Local Point Tracking) application.
