Fig. 70: The corona of the sun. You can see the field lines of the solar magnetic field with the poles at the bottom left and top right. The drop in brightness of the corona from the edge of the sun to the outer regions is so strong that it cannot be captured by a single exposure on slides. — William Optics Zenithstar 105 ED Triplet APO f/7, 2x Nikon teleconverter, Nikon F100, Fujichrome Velvia 100F, 1/2s, Side, Turkey, March 29, 2006
