Subject: Mediocre Saturn

Hi Folks;

I had mediocre seeing on the 16th and shot a few images of Saturn.

http://groups.yahoo.com/group/Astro_IIDC/files/Planetary/Saturn_20080216_MJA.jpg

The images were taken with the C8 at prime focus (2,000 mm focal

length), seeing wasn't good enough to go any longer. With the Flea's

bigger pixels (7.5 microns) I could shoot at 30 fps with low gains,

whereas with the Flea 2 (4.56 micron pixels), I had to use 15 fps and

moderately high gains to get the same brightness.

With Saturn's north pole tilted more towards us, I was surprised to

see how  much more bluish / greenish / darker it is in the north

hemisphere than to the south hemisphere. That's why I did several

saturation versions of the same images.

TTYL..
