Takahashi Tube ring 95S with balancing plate (TKA21420S)

Takahashi Tube ring 95S with balancing plate 

Cradles are the standard tube rings for fixing Takahashi optical tube assemblies to the mounts. Footprints of the cradles are adapted to the heads of the Takahashi mounts. They are systematically provided with two 8.8 mm diameter holes; they are fixed to the Takahashi mounts by means of 2 M8 screws, delivered with cradles. The top of the cradle has a small flat surface with a 1/4"-20tpi screw (Kodak). It is possible to attach a camera to it in parallel.

Takahashi cradles are made of cast aluminium. The finishing of each one is done manually. Felt parts ensure the protection of the optical tube.

As on the Takahashi FSQ-106ED and because of its Petzval type optical formula, the FSQ-85EDX has an oversized cell which receives the lenses of the triplet. The whole assembly is heavy and causes a significant weight shift towards the front of the refractor that conventional tube rings, combined with the short optical tube, make impossible to balance on a mount. To move the center of gravity towards the back, Takahashi thus conceived an offset plate specific to the cradle (ref. TKA21420) and the symmetrical cradle (ref. TKA21420G) of the FSQ-85EDX.

The balancing plate is compatible with Takahashi EM-200 mount.
