The DuoScope allows you to mount a camera or a second telescope on the counterweight bar. This will save you the money for counterweights and significantly reduce the load on your mount. The DuoScope allows you to max out the load capacity of your mount, making it a significantly cheaper option than a larger mount!
This version of the DuoScope is suitable for cameras and small optics.
Suitable for counterweight bars of 18mm diameter.
