The WD-20 is a harmonic mount based on servo direct drive. It offers a standard payload of up to 22kg without counterweight. With an optional counterweight, the load capacity can be increased to up to 30kg! Most heavy equipment like a 150 APO or a C11 can be easily handled with it. The newly designed mount head with a high power density servo motor significantly increases the load capacity, while the actual mount weight remains at only 5.4kg. Both axes are equipped with a home sensor, making remote control/observatory astrophotography even more convenient.
