2001/11/19 Saturn images
I found a dark pattern which moves it to EZs with rotation.
It stopped seeing the white small annular belt which
matched in the vicinity the South Pole.
Best wishes,

The seeing was excellent with very little to no degradation due to the
atmosphere on most sub-exposures. This image probably represents close to
the limit of what the C14 can do as far as resolution is concerned as the
atmosphere was not really distructive during these exposures. Later the
seeing decayed to about 7/10 when I was shooting Jupiter that same mourning.
This image was processed with non linear filters to enhance the visibility
of the C ring.
Eyepiece Projection @ f/68 w/10mm plossel, projected 70mm, aprox..23 arc seconds per
pixel
Integration Times:
6 BLUE + IR rejection, .6 seconds, Edmunds filters
5 GREEN + IR rejection, .6 seconds, Edmunds filters
4 RED + IR rejection, .6 seconds, Edmunds filters
12 no filter .3 seconds for Luminance
Seeing was excellent 9.5/10. Transparency below average 3-4/10, wind calm,
heavy dew, ground fog present.
