0.7X Fast photography focal reducer for the AX103S apochromatic refractor
The AX103S is an amazing, true high performance, field flatness corrected apochromat refractor used by discerning astrophotographers and visual observers alike.
This Vixen AX103S focal reducer compliments the amazing AX103S apochromatic refractor by reducing the primary focal length from F/8 to f/5.6 for fast astrophotography.
The optimal distance of the reducer to the plane of a CCD camera is 63.5mm. Using a T-ring with the Vixen Wide Photo adapter, the distance from the flange of the T-ring to the focal plane is 55mm.
