Sunflower View of the Moon

Originally published August 1, 2012 LPOD-Aug1-12.jpg
image by Ivan Gonçalves, Nice, France

This image of the moon was formed by a single drop of sunflower oil floating on water. The image quality is comparable to the human eye (1 arcmin). This little experiment shows how the laws of mechanics and optics can meet to produce an image naturally. To minimize the chromatic dispersion only the red filter of the image was used.
