This piggy back rail firmly holds my filter wheel so that I can attach a camera at one side and an SLR Photolens at the other side.
The whole rail fits on the piggy back base I have made for my LX200.
The bolts holding the metal angles to the rail pass through slightly elongated holes, enabling small left/right adjustments to line up with the OTA.

Not recommended for heavy weight SLR Photolenses !
