  1. A small plane mirror (as found in women's makeup compacts) can be used to PROJECT an image of the sun on a distant wall.The size of the suns' image (in inches) is the distance to the wall in inches/110.Perfectly safe and lo-tech.
  2. At a pinch, you can use reflective mylar (as used in survival blankets).One to two thicknesses should be sufficient tho the image will will have a strong bluish tinge.wrap around the end of the lens and secure with tape.
