Designed for the G-11 mount, Losmandy's Side-by-Side Dual Dovetail Saddle provides the ability mount two OTA rigs onto your mount head for autoguiding/imaging, or sharing during community events. This side-by-side saddle attaches easily by simply rotating the G-11 saddle 90° without any permanent modifications required. Each saddle accepts large Losmandy-series and smaller Vixen-series plates and is outfitted with dual thumbscrews that are used to tighten the saddle clamps and hold the OTAs firmly in place. The two plates run parallel to each other with 10" (25.4 cm) of separation center-to-center, accommodating OTAs of various sizes. Be sure to check the mount and tripod's payload capacities to ensure the two OTAs and their respective accessories do not exceed the weight limits.
