The Takahashi 156S one-piece mount, part number TKA31420, is designed for the TOA-130 telescope. Its inner diameter is 156 mm, and its listed weight is 2 kg. This part number refers to a one-piece clamp, not a pair of double clamps with an extension plate.
The base of the one-piece clamps is designed to fit Takahashi mount heads. The manufacturer specifies two 8.8 mm holes and mounting with two M8 screws. For a different mount or an intermediate plate, check the mounting pattern and center distances before assembly: the tube diameter alone is not sufficient to ensure a proper fit at the bottom interface.
The upper section features a small flat surface with a 1/4-inch-20 photographic-threaded screw. It allows a housing to be mounted parallel to the scope. This mounting option does not imply a specified load capacity, as no numerical limit has been established here.
The collar is made of cast aluminum with hand-finished details. Pieces of felt protect the surface of the optical tube. Before use, check that the assembly is securely fastened and properly balanced. The telescope and camera mentioned in the usage descriptions are not included with this mount.
