Stalking the Wily Analemma

avi33 writes "Wired has an article on the short list of photographers seeking to capture a shot of the analemma - the sun's figure-eight-shaped declination in the sky over the course of a year. Only a handful of people are known to have done this, and of course the obstacles are many: maintaining the equipment and its positioning, the finicky nature of film, the weather, and the photographer's persistence. Is it just me, or is this crying out for digital automation? Mount a cam to a hardpoint, have it snap a shot every x hours, and overlay them? Why I bet some of you could do this with a perl script in an afternoon. There's a shortage of photos from outside the northern hemisphere, so get busy."
