ASA DDM85XL Premium Direct Drive Mount

ASA DDM85XL Premium Direct Drive Mount

The ASA DDM85XL Premium Direct Drive Mount was specially developed by ASA with the goals of stability, having a high payload, while retaining good transportability! This product is the premium version of the DDM85 line of mounts! It has a loading capacity (telescope and instrument weight) of up to 220lbs (100kg). This Premium Direct Drive Mount incorporates 85mm thick hollow axles, massive tapered roller bearings, and motors providing even higher torque with excellent control. This model is also equipped with very accurate encoders. Not only that: Its outer case is manufactured from high-grade carbon fiber, which means its appearance stands out among the rest. This mount incorporates the mechanical parts, motors, encoders, and ancillary electronic components necessary to operate as a superb Direct Drive Go-To mount, with the appropriate external computer and software. This model also incorporates wiring internal to the hollow axles, so that the USB ports, the Power connector, and the Data Link sockets are located on the mount plate. This eliminates potential tangling of cables which might occur during tracking or slewing! Requires a nominal power source of 24VDC for operation, which can be derived from an optional power supply. This mount can slew up to 13 degrees per second.

The ASA DDM85XL Premium Direct Drive Mount was designed to function as an equatorial mount and to be attached to a tripod or a fixed pier. Because any pier measurements and angles are going to be specific to a particular client's location and requirements, the optional equatorial pier can be manufactured by ASA to be aligned exactly to suit its client's observatory's installation site. This version also includes the following hardware: an ASA 85DC1 Aluminum Dovetail Plate, and two (2) ASA Counterweights, 1 - 35.3lbs (16kg) steel weight and 1 - 75lbs (34kg) steel weight!

Customer Note: This product does not include a pier! One of the photos shows the DDM85XL attached to an optional pier, for illustration purposes only. Since this mount requires a power source of 24VDC at 1 to 3 Amperes during slewing operation, and a maximum peak current of 10A, the user should be aware that conventional 12V AC-to-DC power converter supplies are not adequate for this task! An optional power supply which is appropriate for this application is available for purchase from OPT.

In addition to its impressive loading capacity (instrument weight) of up to 220lbs (100kg), its higher torque motors and guiding accuracy is second to none, and it is truly the premium version of the ASA DDM85 line. Especially important to this design was the expertise of Phillip Keller, physicist and engineer, whose years of experience in the area of large telescope systems was invaluable for ASA's product development!

In common with ASA's other mounts, the ASA "Autoslew" software provides perfect pointing and tracking operation. ASA's Autoslew software package is included with this product, to support automated pointing, precision tracking, and remote control via the internet.
