First Solar Eclipse Photograph
Berkowski made the first solar eclipse photograph on July 28, 1851, also using the daguerrotype process, at the Royal Observatory in Königsberg, Prussia (now Kalinigrad in Russia). Berkowski, a local daguerrotypist whose first name was never published, observed at the Royal Observatory. A small 6-cm refracting telescope was attached to the 15.8-cm Fraunhofer heliometer and a 84-second exposure was taken shortly after the beginning of totality.

Composite of images taken with a William Optics Zenithstar II (545mm, f6.4) and Canon 5D MarkII camera (ISO100), with exposures from 1/90th sec to 2 seconds long. For the outer parts, I have also used some images captured with a Pentax 300mm f4 ED IF lens (1/4 and 1sec at ISO100) and another Canon 5D MarkII. Those two imaging trains were tracking on my trusty old Vixen GP-DX mount. — Phil Hart
