Avalon Instruments Dual Dec Adapter for M-Zero mount

Thanks to the new Dual-DEC system, it is possible to install a second telescope in the opposite side of the declination axis. Considering this capability it is possible to use a great range of optics starting from a small (4-5 kg/8.8-11 lb) refractor up to a double setup with a total weight of 12-13 kg/26.4-28.6 lb, obtaining performances so good to get it over the need of a bigger mount.
