For a first Saturn, it's really very good.
I hope you don't mind, I've played around a bit with the .bmp that you posted. I put it through Registax, resized it and did some work with the wavelets, RGB allign, then put it through Paint Shop and worked on the histogram, shadows and highlights. I've probably processed it a bit too much.
There's lots of detail on the planet's surface.
Again, it was a good capture for a first one.
