| Heliostat (4 m2) in a distance of 200 m from light target point. This picture was taken directly from light target point (4 pictures following): |

| Across several premises the sunlight is directed into the living rooms window of a dark shaded house. |

Light beam target. This photo was taken in the evening right before sun goes down. The heliostat is still in sunlight and reflects the light onto the lighted point to be seen clearly. This is an original genuine photo showing the existing relations of light. |

| The light, unfortunately, hits this window in a very flat angle. You can see that in the downpipes shadow of the rain gutter and the light reflexes on the window pane (left). By this you may realize the high yield of light too. The light beams boundaries are clearly remarkable. Please respect the extreme long distance of 200 m. After every 20 seconds the shifting target reflex caused by the progress of the sun is set back to the target. This corresponds roughly to a correction angle of 0.1 degrees. The mentioned accuracy of 0.3 degrees represents a shift of only ca. 55 mm in a distance of 10 m, 0.5 m in 100 m distance and ca. 1 m in a distance of 200 m. The blurring effects at the borders of the sun reflex occur due to the dimensions of the sun disc with an aperture of about 0,5 degrees, therefor only minor parts are caused by the reflectors roughness. At lower distances the results are accordingly better. |
