Here is a spectacular photograph of the Moon made last night by my good friend David Ada-Winter in light-polluted New Jersey:

David explains: “I took this picture of the Moon using the so-called Sunny 16 rule, the essence of which is the following: On a clear day, with an aperture of 16, the exposition time must be the reciprocal of the ISO value. In the case of this picture, the ISO was 200, so the exposition time was 1/200 with an aperture of 16. In front of my telescopic lens, I also used a doubler that extended the focal length to 800 mm. The picture itself was made with the Canon Rebel t2i camera, which has a crop factor of 1.6, allowing the Moon to appear even larger in the image.”

Apparently, David’s wife disapproves of his pricey hobby. I’m tempted to remind her that other men of David’s age often acquire even pricier hobbies, which usually involve brightly colored sports cars and lightly clad ladies…
