Thanks Holly!
Pick only the best frames
rubbish stacked is still rubbish. The faster the capture the better, but at the same time you have to balance signal/noise with your camera to find a sweet spot. I've been using unity gain with my 224 for most of my captures recently. F-ratio is also important in image brightness. You want good (but not oversaturated) bright images in your capture. That can be more tricky with Saturn as it's not as bright as Jupiter and Mars.
I used a couple of points on the rings as a white point reference for colour balancing. Some guys with mono cameras get a lot more blue in the rings, and the 224 is a bit weak at the blue end. I really like the blue-white ring renditions I see by the great imagers here, but I'm not game for drawing weak signal out of my data. I'm also - not yet - game to jump in with a mono sensor
