This diagonal prism comes with my LX90 and is seldom used.
It has some set screw marks and slight scratches on the housing. Other then these, the optics is excellent. The prism is very clean with no scratch.
Quality of Meade's prism diagonal may not be very stable, but this one is an outstanding one optically. I compared it with my Televue standard mirror diagonal but can hardly see any difference.
