The Fifth Imaging Session

A night of very good seeing (about 8 on a scale of 0 to 10) produced this decent image of Jupiter. The image of Ganymede at left has been artificially brightened. Unseen in this image was a nice view of dark Callisto passing across the southern extremity of Jupiter. Io and Europa were behind the disc at the time this picture was taken, in a double eclipse. North is up, east is left.

Saturn was glorious through the eyepiece, and this shot is marginally better than the one from the Second Session. The ringed planet was perfectly steady, and the Cassini division, though not visible here, was evident almost everywhere except at the very center of the planet. Clearly visible here is the white equatorial zone and the darker temperate zone (both areas being in the southern hemisphere). As before, north is up, east is left.
