ASA DDM60 Pro Direct Drive EQ Mount 28kg Load

The ASA DDM60PRO is ASA's entry level mount series and is especially designed as a portable device for astrophotographers working in the field. The mount – like her two "bigger sisters" the DDM85 and DDM160, comes with all the features you would expect of a professional telescope mount.

Currently the smallest available member of ASA's mount series, the DDM60 was specially developed with the prime focus on transportability and stability (4 tapered roller bearings). This is mirrored in the light weight of the coordinate axes which only weigh 19kg without the counterweight shaft.

The built-in laser and supplied software allow for an exact positioning of the mount in only a couple of minutes. Setting up the mount in the dark is very simple due to a well thought out telescope mount adapter, which allows for a secure and fast attachment of the telescope to the mount. Since direct drive motors usually have a high power consumption rate, ASA developed its own low consumption motors together with a well established German company. The mount can easily be operated all night long on a single 12V battery. Even during fast slews, the mount will not use more than 1 to 2 amps.

The DDM60 is available as a standard or 'PRO' model version. This version of the DDM60 comes with a 3-Port USB Hub in the Dec axis, two extra galvanically separated power lines (to power up your camera, filter wheel etc.) as well as an extra data line that can be utilized for serial data connections. All cables are pulled through the hollow axis of the mount, so that tangling of cables can be prevented during operation.

We keep the DDM60PRO on demonstration.
