The attached image is an observation made on October 29, 2002 at 06:20 U.T.
Much detail was noted over the globe and rings under good (7-8/10) seeing
conditions. The richness of detail was made possible by the high contrast
and sharpness provided by my new custom 9-inch F/13.5 Maksutov-Cassegrain. I
hope that you enjoy my observation. Any comments would be appreciated. The
following is the data for the observation;


Globe:
South Polar Region (SPR): Appeared dark (3/10) with a central spot (2.5/10),
but no other detail noted within.
South Temperate Zone (STZ): Appeared dusky to dull (4-5/10) with the
southern half greenish in hue and the northern yellowish cream. No detail
was noted within this region.
South Temperate Belt (STB): Appeared dusky (4/10) and thin, but no other
detail noted within this region.
South Tropical Zone (STrZ): Appeared shaded to bright (6-7/10) with a thin,
dull (5/10) band bisecting it.
South Equatorial Belt (SEB): Appeared dark (3/10) and broad (especially the
portion preceding the CM), but no detail noted within.
Equatorial Zone (EZ): Appeared bright (7/10) with a thin, interrupted dull
(5/10) band bisecting it. No other detail was noted within this region.

Rings:
Ring A: Appeared dusky (4/10) with Encke's Minima noted throughout,
especially over the ansae.
Cassini Division: Prominent throughout, but no detail noted within it.
Ring B: The outer half appearing bright (7/10) and the inner half dull
(5/10). No spoke activity noted at this time.
Ring C (Crepe): Appeared dull to shaded (5-6/10), especially notable across
the EZ.

The best of luck in your own observations and imaging. May you all have
clear and steady skies.
-----------------------------------------

I have taken my monochrome observation of Saturn made on October 27, 2002
(06:20 UT) and added color to it according to notes taken at the time and
color images of the planet obtained at the approximate period by Damian
Peach. The data for the observation is as previously sent. I hope that you
like it and any comments are welcome. I hope to make more color observations
in the future.
The best of luck to you all and may you have clear and steady skies.
