During the recent surge of the solar images, many of them were photographed with the 1/2″ CCD, or DMK 41 lines, astronomy cameras. French amateur astronomer Etienne Lecoq, for instance, equiped himself with a DMK 41AU02.AS astronomy camera and took the following pictures approximately two weeks ago.
His e-mail is translated as below:
