The image of the full moon above was taken at the minimum perigee for 2008 as well as for the period 1993-2016. The final step during processing involved the inversion of the monochrome image so that the mapping of white and black as well as the various intermediate shades of gray would be reversed. This technique is very useful and commonly employed for the identification of faint detail which would otherwise be more difficult to ascertain in a normal image. As indicated by the image above, features such as impact craters and ejecta as well as minute crater(let)s are now more visible with greater subtle detail and form. Technical Details: Date: Dec 12, 2008 23:33:18 UT+2 Location: Athens, Greece (38.2997° N, 23.7430° E) Equipment: AP 160 f/7.5 StarFire EDF, AP 1200GTO GEM, Canon EOS 350D Exposure: 1 x 1/250 sec, ISO 100, RAW image format, 3456x2304 image size, Manual Mode Further Details: http://www.perseus.gr/Astro-Lunar-Scenes-Perigee-2008-Inv.htm
