FL67 Takahashi flattener for TOA-150/130 (TKA32583S) REDUCED
A must for imaging. Bought in 2021. Excellent condition. Cost $1,408 plus taxes new. I include the 17 mm spacer for the TOA-150 (82 on the chart) and the visual adapter (83 on the chart). For a TOA-130NFB, you need to buy the 25 mm spacer (TKA31584) or put a 8 mm spacer somewhere after the flattener and the 17 mm spacer.

Often referred to as a "super-flattener 6x7", the Takahashi 67FL field corrector has superlative mechanical and optical characteristics, an exceptional 90mm diameter corrected image circle, covering medium format, and a weight of 700g. It is designed for use with TOA-130NFB and TOA-150B telescopes equipped with the giant focus system. Historically, Takahashi designed this corrector to enable silver photography with the Pentax 67 camera, whose film surface measured 6 x 7 cm.
The 67FL corrector is equipped with a female M92x1 thread at the telescope side. It is screwed directly onto the output of the Camera Angle Adjuster (CAA). The camera side is with a maleM92x1 thread. The output mounts of the corrector are different according to the model of refractor used, in order to obtain the optimal backfocus of 106.2 mm for each optical tube assembly. On the TOA-130NFB, the output ring #82 provides a 25 mm output (TKA31584), while on the TOA-150, the output ring #82 provides a 17 mm output (TKA26583). This field corrector is not compatible with the TOA-130NS refractor because the focusing system of this refractor does not accept accessories with M92x1 threads.
Price: $750
