Image 19/27: 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, William Optics Zenitstar d=105mm f=735mm, 2x Teleconverter, ISO 200, 1/13s, Falera observatory, 22 May 2007
