Reasonable seeing on Sunday evening despite the low altitude (18 degrees). Europa's shadow was easily seen in transit across Jupiter, Europa itself was more difficult to see.
2009 Sep 13, 2154 UT +/- 1 min. Celestron CPC1100, prime focus, Astronomik RGB colour seperation filters + Planet Pro 742 (for luminance), Imaging Source DMK41 camera, processed in Registax 5 and Astro Art.
North is up: Europa is the bright point on the equatorial zone near the west (right) limb. Its shadow is near the centre of the disk. Io is visible at the left edge of the frame.
CM (I) = 268 CM (II) = 172
