Hi Troy,

A top effort at imaging Saturn.
Troy a few tips, not that I am an expert.

1) Don't be afraid of using very high gain, probably max gain for the blue channel.

2) Pay very close attention to the histogram, try for the same histogram for each channel. Not sure what capture software your using. I use IC Capture and aim to maintain the histogram for each channel at 190 / 200.

3) Obviously you want to capture the highest number of frames in the shortest possible time. If I am trying to identify storm structure I limit my capture time for each channel to about 1 minute at 30 fps and 1/30th second exposure. The aperture of your scope plays a major role in the gain, histogram and exposure you can get away with.

4) Be absolutely fastidious with collimation and focus.

From the images you have posted you are doing a good job, try experimenting with your settings to see what works best with your system.

Regards
Trevor
