Hi all
Here are some observations from dec 20.

-one image taken with ToUcam raw mode with also moon Dione captured.

The Saturn globe is showing some nice colors again (SSTeZ with an ice-bluish color bordered
to the obvious yellow SPB)
Also 3 observations in the normal mode with at 10 fr/s.


Hi all
I was surprised to see that I've captured the globe through the A-ring, clearly visible on this image.
It needed to be printed dark to see the effect well,so the NPC,normally visible on the other side of
the ring,isn't visible anymore.

Hi all, here are some images taken under good seeing, although quite different following the wavelenght - very good in red, good but not more at the eyepiece, and fair in blue or UV light.
The mewlon has a little problem of astigmatism as the primary looks constrained a bit - the problem will be solved with the help of the dealer.
The color image is in RGB as the L image (not shown) was not really good.
Regards



I'm sending again the december 20th set of images as I have added a R image showing a dark spot (arrowed). 
They also provide a good comparison for the rings which really looked duller one month ago.
