The Takahashi FSQ-106ED has an oversized cell which receives the lenses of the triplet. The whole assembly is heavy and causes an important weight shift towards the front of the refractor that conventional tube rings, associated 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. TKA23420) and the symmetrical cradle (ref. TKA36420G) of the FSQ-106ED.
The balancing plate is compatible with Takahashi EM-200 mount.
