This paragraph describes the Saturn occultation by the Moon of November 3, 2001. The entrance phase was visible between 20:56:57 and 20:58:22 (UT) and the emerging phase between 22:00:50 and 22:02:28 (UT). The occurrence of such a phenomena is unfortunately not frequent, but it happened several time on the period 2001-2002.

Images of the MoonThese images have been taken between the entrance and the emerging phases of the occultation. The experimental setup is identical and the exposure time is still 40 ms for all pictures.
Zoom on SaturnThe two following zooms on Saturn are obtained from the image displayed on the top of this page. The image processing (Fourier analysis/correction) has been performed by Raoul Behrend. The division of Cassini becomes clearly visible. For further enhancement of the resolution, multiple shots images with statistical averaging are required. The example presented here is close to the limit achievable with a single shot image obtained with a 200 mm aperture telescope.
The next images are obtained from the combination of 13 single shots with exactly the same setup as described above. The image processing (unsharp masking and image addition) has been performed with the freeware Iris 3.5.4. The resolution can be further increased by compositing a larger number of images.
