The Tele Vue 60 telescope can be attached to Schmidt- Cassegrain scopes 8" or larger for use as a "superfinder". The MBC-1001 Mounting Block Adapter is used to attach the AAM-0001 X-Y Adjustable Mount to the SAB-1001 SCT Accessory Bracket. This part is normally permanently attached to the X-Y adjustable mount U-channel with 2 #10-32 button head screws.
The AAM-0001 X-Y Adjustable Mount and the SAB-1001 SCT Accessory Bracket are sold separately. These two items and the MBC-1001 can be purchased together as Tele Vue part # AAC-0002.
