I had 2 of these custom made 3-D guidescope mounts -- sold the black anodized one on 6/23/04. The second one is original aluminum (same style as one shown in photo). This mount accepts scopes or camera lenses up to 4 3/4" diameter. Mount allows adjustments in X and Y axes without need to mess with ring bolts. Will mount only to 8" SCT tubes. Asking $200. Comes with extra nylon bolts for smaller OTAs and necessary hardware for mounting onto SCT. Will split cost of shipping within CONUS.
