Takahashi TOA-35 0.7X Reducer & Camera Ring – TOA-150, TSA-102/120
The TOA-150 0.7X Reducer and Wide Camera Mount Set by Takahashi:

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-percent.

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 when used with the TOA-150. Images sizes for the TSA-102 and 120 are 8 microns at center and 12 microns at the edge. There is also an improvement in the color correction on all models. The 0.7X Reducer is supplied with a wide mount, 55 mm adapter to attach the reducer to the customer’s camera.
