Comments | It took me one and a half month to achieve this relatively satisfactory result. Earthlit lunar silhouette was vaguely discernible to the naked eye visually, however, it eluded my photographs, probably due to the negative factor from a layer of faint high thin clouds. North approximately up. |

I contributed the raw images to Miloslav Druckmüller, who has created an marvelous wide angle image of the corona along with images from Robert Slobins and Constantinos Emmanouilidis. |
