Analemma photographed over the Temple of Zeus in Athens, Greece

Anthony Ayiomamitis

One of the most difficult photographs in astronomy is capturing the image of the sun's analemma over the course of a full year. Photographer Anthony Ayiomamitis is one of half a dozen or so photographers who has captured the analemma on film and the only photographer to capture multiple analemmas. Indeed, he has photographed 10 of them! Please see the editorial about Anthony in this issue of The Citizen Scientist, Editor.

Photographing the analemma is a lot of hard work but the end always justifies the means and the intervening pain and frustrations.

I know Dennis di Cicco personally, and it was his article in the March 2000 issue of Sky and Telescope where he described the five analemmas in existence at the time which inspired my six-year marathon to pursue this wild but rewarding project.

Here are the technical details:
