Image 27/27: Saturn occultation

The end of the Saturn occultation by the Moon. The pictures from the beginning were too bad because the objective lens was decollimated. I had to collimate it during the eclipse. If the rear lens pair is just 1mm out of center then the picture is very unsharp and has color seams. — Nikon D200, 1/13 s, F/7.1, 800 mm, ISO 200, Tuesday, May 22, 2007 21:34:48
