Mounting System - Duoscope
The main advantage of the DuoScope system is the weight reduction compared to a conventional assembly, where the secondary telescope or camera is mounted on the main telescope and its weight must be compensated with the addition of counterweights on the bar.
With DuoScope the secondary telescope and/or camera is/are fixed to the bar, replacing the counterweights, so that it may even reduce the original weight of your mount.
