Hi, I've just stacked the following RGB composite of Saturn's ring shepherding moon
http://setisociety.org/PrometheusRGB.jpg
It shows different details than the one recently posted by others at
http://www.skyandtelescope.com/news/80364597.html
including the relationship of the ring angle to the mini-moon.
I grabbed the three individual grey scale RGB images from the Cassini raw-images site before they cycled off of it.
The red, green and blue dots are noise artifacts from their respective images; I still have to learn how to mask them out using GIMP (the program I stacked them with.)
