Takahashi Super Reducer for Takahashi TOA130 with 4" focuser, TOA130R

The Takahashi TOA-130 RD Reducer is ready to make your Takahashi TOA-130 turn into the fast focal ratio you want for your most demanding astrophotography needs. Just put this focal reducer into place on either the 2.7" or 4" focuser and instantly transform your system into an f/5.76

This super focal reducer is designed specifically for medium format (6x7) photography with the 4" focuser Takahashi TOA-130F refractor, but can also be used with DSLR, 35mm film, and 35mm and larger CCD imaging chips. It has female threads that attach to the male threads of the 4" focuser drawtube. The back end of the reducer has male threads that duplicate the focuser drawtube threads for attaching accessories.

The fully multicoated optics of the reducer cuts the focal length and focal ratio of the TOA-130F to 780mm and f/6. This produces a 65mm diameter 4.78ıı flat field image circle. This image circle is larger than the 44mm diagonal of a 35mm film negative or a 35mm-size CCD chip. This yields fully unvignetted photographic images with pinpoint stars to the very edges of the frame with these cameras. There will be some vignetting at the top and bottom of a medium format 6x7 film negative.

The finely machined black-finished metal cell of the reducer is supplied with thread-on/thread-in metal covers to protect its attachment threads.
