Fig. 16: Begin of the Saturn occultation of the Moon. Unfortunately the image is not sharp. The lens of that cheap china telescope was not properly collimiated. I collimated the telescope during the time while the Saturn was behind the Moon. — Nikon D200, William Optics Zenitstar d=105mm f=735mm, 2x Teleconverter, ISO 200, 1/13s, Falera observatory, 22 May 2007 Nikon D200; Δt=1/10 s; f=800 mm; f/7.1; ISO 100; 22 May 2007 20:23:06
