Sunflower View of the Moon
Originally published August 1, 2012

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.
24/09/2010. Exposure time: 1/50 s; diameter of the image of the moon: 2.2mm; length of the lens of oil: 25mm
