The M-due Fast Reverse is a single arm fork mount devoted to deepsky imaging in the capacity range up to 25 kg in single telescope configuration and up to 32 kg in double telescope configuration.

The M-due design put together the M-uno and the M-zero mounts concepts, adding two very important features as the High Resolution ABSOLUTE ENCODER and the new StarGo2 Pro controller.

A robust mount base, an high payload capability and more then 6 positions available for the DEC arm on the RA axis. In this way it is possible to achieve the best balancing by using as less as counterweight possible.


With the M-due mount, the Avalon Instruments exclusive Belt Drive System has been now improved by adding High Resolution ABSOLUTE ENCODER.
