Takahashi TOA-35 0.7X Reducer & Camera Ring - TOA-130
The ideal design for a reducer is its ability to reduce the f-stop while flattening the field and controlling chromatic aberration. The Takahashi TOA-35 0.07x reducer is configured with 4-elements in three groups and uses low dispersion, high refractive index glass for two of the elements, while reducing the focal length by a factor of 30%.
The Tak TOA-35 reducer produces 3-micron stars in the center of the field and 6-micron stars at the edge with a very flat field. There is also an improvement in the color correction. The 0.7X Reducer is supplied with a wide mount 55mm adapter to attach the reducer to the customer's camera.
