Hi Sam, ;)
Hi all,
That's a real challenge to produce decent images of Saturn from my imaging spot
in France, Saturne is less than 21° over the horizon ! :
Moreover, I choose the classical RGB way for this picture.
As I ever do, I use manual sort out of all raw images. It takes weeks
but in my opinion it's worth to do it especially in these difficult imaging
conditions !
I'm a little bit disappointed as the great storm is not visible. It's on the
hiden side of the planet...
In the field, Rhea, Thetys and Dione moons are visible. Encelade and Mimas
should be here but haze and atmospheric absorption cuts too much light and
they are lost in sensor noise.
